“Those standards have also informed our requirements for e-motor and inverter-specifi c performance parameters, EMC, electrical safety, durability and cable routing. They therefore mainly just increase electrical resistance and heat, causing losses in energy efficiency. The company’s motor control software has therefore been developed with a modular and common architecture to enable compatibility with varying inverter hardware, as it expects future advances in inverters to rapidly enable higher switching speeds and therefore further improvements in motor control and efficiencies. Four Elaphe L1500 gearless electric motors were mounted on each wheel, giving this first-generation BMW X6 a completely different setup that allowed it to spin just like a tank would, by controlling the way each wheel moves, independently. Elaphe uses an SUV test vehicle to simulate severe braking and cornering scenarios, “At each stage of this approach, we have worked on the basis of analytical equations that have afforded us an insight into holistically optimising our motors’ designs and dimensions, to meet a broad envelope of performance and environmental requirements as well as other evaluation criteria.”. The L1500 has been designed to enable it to be used in a wide range of OEM EVs and HEVs. Techmalak - 197 Followers, 166 Following, 1333 pins | Modernize your man cave in style with vibrant high-res posters printed on metallic photo paper. “The combination of the maximum Hertzian contact stress and the strain corresponding to the maximum allowed air gap deviation yields a specific bearing requirement, called the ‘tilting stiffness’, which is typically between 7 and 10 kN/° and which also encompasses extreme cases,” Gotovac says. Elaphe, a Tier One supplier to the auto industry, will begin production of its L1500 in-wheel electric motor with up to 1,500 Newton-meters of torque in the 4th quarter of 2019. The M700 was the first motor Elaphe fully validated according to existing automotive standards, and both motors have some architectural similarities. 370 VDC nominal voltage. A single in-wheel motor can achieve a power output of more than 110 kW (147 HP) and fits inside a 19-inch or larger wheel rim. Automotive manufacturer Hyundai has a new incentive to lure buyers to its offerings with the 2016 Hyundai Elantra and the new Value Edition. This premium large-venue projector features native WUXGA performance with Epson® 4K Enhancement Technology1. For broader and closer accuracy of how the bearing will behave over its lifetime, Elaphe then conducts experiments using the Wheel Accelerated Life Test machine (WALT) at the Fraunhofer LBF Institute for Structural Durability and System Reliability in Darmstadt, Germany, with additional similar tests locally on dedicated deflection measurement benches. We have focuses on fuel cells, measuring equipment and ECUs. Most of these segments have high growth potential, and they also benefit from a real four-wheel-drive capability with torque vectoring and brake blending in a compact package.”, Permanent magnet, three-phase synchronous AC motor, External rotor with surface-mounted magnets, Internal stator with pseudo-helical multiphase wave winding, Maximum power output: 113.6 kW at 370 V DC, Continuous power output: 65.3 kW at 370 V DC, Continuous power output with field weakening: 83 kW at 370 V DC, Diameter: 464 mm (fits standard 19 in rims), Axial length: 142.2 mm (hub-to-rim attachment is less). For one, the company has observed that the market for in-wheel motors has very diverse requirements, with many different vehicles and value propositions. In the first year, the PRODRIVE team has delivered the first vehicle, a converted BMW X6, powered by 4× Elaphe L1500 motors, controlled by Elaphe PCU (Propulsion Control Unit) with a total output of 6000 Nm, 440 kW and an overall impressive acceleration and cornering performance. “Combining those two aspects makes our measuring stations uniquely ‘universal’ in their ability to test motors of widely different types and characteristics, while complying with automotive standards.”. (Earlier post. These consist of 18 shocks, each measuring 100 g (in force) as well as 60 more shocks of 50 g each. All this being said, the company has for more than 10 years now been developing its competencies in integral inverter topologies for in-wheel motors. “This has two critical benefits. >110 kW peak, 77 kW rated. Direct-drive synchronous AC motor: Liquid cooled, compact, high-torque (1500 Nm) for electric vehicles. Lordstown Motors licensed the L1500 in-wheel hub motor from Slovenian tech company Elaphe Propulsion Technologies. Four Elaphe L1500 gearless electric motors were mounted on each wheel, giving this first-generation BMW X6 a completely different setup that allowed it to spin just like a tank would, by controlling the way each wheel moves, independently. Scalability of the company’s design processes has been critical for conceiving the structural architecture of each new L1500. That’s also helped refi ne our proprietary processes for how to make the windings as short as possible.”. “The exact length of each band is customised for the application to achieve the correct voltage balancing in each wire, and by extension the right speed and the torque for the motor, without any detrimental effects on current losses,” Gotovac adds. Moreover, in November 2018, Savic Motorcycles announced a new electric motorcycle model Cafe Racer and will launch it by 2020. As Lampic notes, every component in each L1500 must be designed for ‘multiphysics efficacy’, capable of handling many different kinds of thermal, structural and electrical loads. Elaphe therefore anticipates considerable customisation and differing production cycles for each motor. Elaphe, a Tier One supplier to the auto industry, will begin production of its L1500 in-wheel electric motor with up to 1,500 Newton-meters of torque in the 4th quarter of 2019. Examples of these are thermomechanical stress due to excess heat from electromagnetic losses in the copper windings, steel laminations and permanent magnets, and frictional losses in the bearings and seals. Which also means that they can make that pack for a VERY decreased price. Contact a supplier or the parent company directly to get a quote or to find out a price or your closest point of sale. LM will build those motors in its Ohio plant, alongside the trucks that will use them. Power Transmission - Mechanical components, direct-drive, with brake, traction, for electric vehicles, external rotor, permanent magnet, liquid-cooled, compact, high-torque, high-power. However, wire strands can suffer significant damage as a result. This rests on putting the bearing and the motor through cornering, endurance and durability tests (in accordance with SAE standards J328/2016-03 and J328/2005-2) to see how it sustains loads (reducing their transmission to the rest of the motor), and whether contact in the air gap occurs at any point. A Better Way To Travel. As the CEO notes, Elaphe’s proprietary holistic motor optimisation algorithm takes into account (among other information) a wide range of magnet parameters as it evaluates an overall motor design. Its development originated in the early 2000s, with intended (and achieved) benefi ts including improvements in specifi c torque, energy effi ciency, ease of assembly and ease of cooling relative to traditional coil-winding approaches. In addition to its in-house testing facilities, Elaphe also sometimes uses third-party testing facilities for more conventional or specialised tests, such as for vibration, shock, environmental IP rating and EMC. 1500 Nm peak, 650 Nm rated. “OEM and international standards in particular have been adapted to cover location-specific environmental and structural load requirements, which differ greatly for in-wheel motors compared with centrally mounted e-axles, as they are usually derived from structural and electrical components that reside in the wheel in ICE-powered cars. That’s especially impressive considering how gas prices have remained low, ... Small Package, Enormous Power : The Elaphe L1500 In-Wheel Motor. For example, e-motors on heavy commercial and off-roading vehicles will endure higher external loads owing to harsher interactions between tyre and the road. It is a … The described assembly of rotor, stator, brakes and bearing transfers loads from the road (which will vary depending on vehicle weight, braking dynamics, cornering and ground roughness) directly to the vehicle knuckle via the bearing, protecting the electric motor components from such impact loads. For example, in lap winding, each continuous strand of conductor wire can be damaged as it is inserted into and twisted around the stator teeth. Although such studies and simulations might seem premature, identifying the many loads that act on in-wheel motors (and the resultant effects) were critical to defi ning the design targets for the L1500’s component architecture and optimisation. The selection of an adhesive for bonding the permanent magnets in their slots is tested and validated in a similar way to the structure of the rotor and stator. “In parallel with the high-torque requirement, we’ve constructed them in a way that avoids resonant frequencies when testing motors at very high speeds. Before iterating the key aspects of a new L1500’s design through CAD simulations, Elaphe fi rst selects the key peripheral components (including the rim, brakes and bearings) in order to defi ne how much space is left for the stator and rotor. “In general, our testing strategy is based on three factors – testing based on OEM and international standards, then legislation, and lastly, internally identified tests based on design failure mode and effect analysis exercises, vehicle tests and simulations,” Lampic says. The designs yielded from topological optimisation are then run by an industrial designer, so that they can advise on precise guidelines and limitations regarding how the CAD drawings can be feasibly and accurately reproduced in the real world. Ease of integration and component logistics have also been strongly prioritised by Elaphe during its design of the L1500. LM will build those motors in its Ohio plant, alongside the trucks that will use them. Find out all of the information about the Elaphe Propulsion Technologies Ltd. product: direct-drive wheel hub motor L1500. Within 5 minutes the L1500 can be integrated into or removed from a car wheel for routine maintenance, such as brake inspections and replacements. Lordstown Motors licensed the L1500 in-wheel hub motor from Slovenian tech company Elaphe Propulsion Technologies. Convertible upflow or horizontal design, the Elite® Series 6-20 Ton large split system air handlers combine MSAV (Multi-Stage Air Volume) and up to two stages of cooling to provide temperature control and enhanced humidity control. (www.prodrive-electric.com).SOURCE Elaphe Propulsion Technologies Ltd. The FEA includes static simulations (that is, one-off impacts) of how stresses and deformations would be distributed across the motor under varying load speeds, the levels of and ways in which friction occurred between components and connections, and other properties of the design’s structural integrity. Being Elaphe’s largest and most powerful in-wheel motor yet, the project represented new territory for everyone involved. See the Epson Pro L1500 series lenses here! While normal bearing deformations aren’t a major problem, excessive deformations in an in-wheel motor can cause defl ections between the rotor and stator. ELA150S4D-1Y. “As we see it, the expected trajectory of transistor advances is too fast to commit to one specific technology that we can confidently wrap our motors around,” Lampic says. Elaphe integrates (from left to right) standard-issue tyres with 19 in rims, the L1500 housing (and rotor), its stator, standard automotive brakes and a standard bearing, to mount to the vehicle knuckle. There is no tightening or straining of them, as might happen with copper strands, or any post-deformation as with hairpin stator conductors. A thermal camera also records complementary data, and laser sensors measure axial and radial deformations of the rotor. “What we did – in our capacities as physicists – was to analyse the electromagnetic, thermal, mechanical and control aspects of the motor simultaneously, from the outset of the L1500’s development. Elaphe L1500 high-performance direct-drive in-wheel electric motor with standard disc brake and bearing (1500 Nm peak torque). Elaphe is investing heavily in R&D and scaling up production, and was recently awarded a grant of over 1 million EURO by the European Union to co-fund the industrialization and commercialization of the innovative Elaphe™ L1500 in-wheel motor, bringing it into mass production . )Clean Energy’s Zero Now program makes the cost of leasing or purchasing a new natural gas heavy-duty truck equal to the price or even lower than that of the same truck equipped with a diesel … best rc boat kits ideas and get free shipping. “With more experience and our model accuracies optimised, we replaced the N40UH with N40SH, the latter being in the 150 C temperature class.”. ... Small Package, Enormous Power : The Elaphe L1500 In … Some of those loads acting on the L1500 are internally generated. Highlights in this issue include a dossier on the Elaphe L1500 in-wheel motor, a conversation with Henrik Fisker the founder of Fisker Inc and a digest on the vRbikes vR3 tricycle. LA 150-P – Current Sensor 150A 1 Channel Hall Effect, Closed Loop Bidirectional Module, Single Pass Through from LEM USA Inc.. Pricing and Availability on millions of electronic components from Digi-Key Electronics. However, most of its systems are designed to operate with the inverter on the vehicle chassis rather than inside the wheel housing. In the first year, the PRODRIVE team has delivered the first vehicle, a converted BMW X6, powered by 4× Elaphe L1500 motors, controlled by Elaphe PCU (Propulsion Control Unit) with a total output of 6000 Nm, 440 kW and an overall impressive acceleration and cornering performance. Elaprase Prices, Coupons and Patient Assistance Programs. These simulations must show that the degree of deformation never exceeds a certain (undisclosed) value, thus ensuring no impact between the windings or permanent magnets can occur. The Italian design company Icona announces its debut at the 88th Geneva International Motor show, unveiling a worldwide premiere: the autonomous driving concept vehicle Icona Nucleus. It also comes with an integration of electronic parking brake caliper in addition to the main friction caliper. “In relative terms, far fewer wire connections need to be made, which improves consistency of quality, reliability and production costs. Moreover, in November 2018, Savic Motorcycles announced a new electric motorcycle model Cafe Racer and will launch it by 2020. For instance, Elaphe provides L1500 in-wheel motor that has a peak power of 110 KW, with a speed of 1,250 rpm and can be cooled by using the liquid cooling method. Clean Energy Fuels Corp. has reached agreement with trucking firms to lease or purchase more than 250 new heavy-duty trucks, fueled by its Redeem RNG (renewable natural gas). Elaphe's high-performance in-wheel motors are designed for integration in vehicles … As Lampic says, “We wanted to bring what we feel is required for improving future OEM EV/HEV models. Also, the bands’ overhangs are pre-formed in a ‘pseudo-helical’ way, bending perpendicularly and radially relative to the stator slots, to minimise the volume of space they take up and how far they protrude beyond the stator teeth. The heat transfer coeffi cient of copper is better than any of the other materials in the motor, so the more copper, the better the thermal effi ciency and the lower the heat losses. As packaging and cooling requirements change with different inverter technologies and topologies, having the inverter on the vehicle chassis means it can be swapped out relatively easily, compared with trying to force an entirely new inverter into the old one’s space. Elaphe's high torque motors are based on a new electromagnetic topology, which enables all of the desired properties of an in-wheel electric motor. As with hairpin stators, compact multiphase wave winding uses thick, pre-deformed ‘bands’ (essentially long, thin rods) of copper, rather than strands or thin sheet-cut tapers, for its conductors. After ascertaining the stiffness of the bearing, deformation analysis of the air gap follows. “Our insights and models for e-motor optimisation are part of our proprietary knowhow,” Lampic adds. To ensure each motor provides precise and reliable performance over its lifetime, regardless of differences between vehicle chassis and complementary parts, Elaphe has a rigorous set of design requirements, simulations and testing processes. As with the previous fatigue simulations, both tests are performed in accordance with ISO 16750-3:2007. First, the stiffness of the customer’s preferred bearing is characterised using Elaphe’s in-house numerical analysis software. Elaphe, headquartered in Europe, is a world leader in-wheel motor technology company and supplied the motors for the Nucleus. Some testing is repeated for each new set of customer requirements to revalidate a customized version that meets the requested bearing, brake, vehicle and performance targets. Its endurance and durability are examined across temperature cycles, load cycles, humidity, shock and vibration to ensure the magnets will remain secured in all modes of use in a modern passenger car. Elaphe has therefore developed a regime for validating the stiffness and durability of bearings before it will integrate them into the L1500 (or its other in-wheel motors). To help the electric BMW X6 perform the tank turns, Elaphe Propulsion mounted four Elaphe L1500 gearless electric motors to each wheel. As a result, there are three high-flex phase cables and two signal cables in the wiring harness for connecting inverters to the L1500. Our innovative in-wheel motor technology generates power directly in a vehicle’s wheels. AISIN Group Launching a $50 Million Automotive Fund Focused on Silicon Valley Technology. Elaphe’s method is called ‘compact multiphase wave winding’. The Elaphe L1500 in-wheel motor is currently the brand's highest-performance product, producing 1500 Nm peak torque which available to each wheel throughout the speed range, delivering 110kW of maximum power to each wheel. THE concept N… To minimise the effects on the air gap, the bearing must be able to sustain suffi cient external loads to prevent them passing through to the rotor and stator. Second, the cooling system is positioned in such a way that it also intrinsically shields the electromagnetic part from heat transfer from the brakes.”. For instance, in May 2018, Elaphe Propulsion Technologies Ltd. launched the Elaphe L1500 two-wheeler hub motor. These are issues that cannot be isolated to singular components or sections thereof. I love the amp, and am glad I purchased it. The battery pack – … “The advantage, compared with hairpin stators, is that our overhangs are much shorter, meaning less losses,” Gotovac says. Lawrence Butcher investigates the technology and engineering behind this compact but powerful motor design Axial flux motors have seen increasing adoption across the e-mobility industry Something of the new kid on the block in the world of electric machines is the axial flux motor. Want To Be A Human Guinea Pig ? Given this need to stay flexible for typical in-wheel motor customers, designing the motors around integrated inverters would have meant driving up design and component costs for each customer. For example, an EV designer could choose to have a dual-inverter integration in a single housing, which could use a singleloop cooling system, share a single logic board, faster comms for full axle control, and so on,” Gotovac says. “So, we must use 20" tires. best price holders plastic list and get free shipping. Elaphe's wave-winding technique installs continuous lengths of copper into the stator teeth to minimise the 'overhangs' that lower energy efficiency. It’s what we call our ‘multiphysics’ approach,” says Lampic. To reduce the price for the mass market, the battery module, motor and inverter selection would most likely be driven by more economically viable, higher volume solutions, he added. The most powerful (110 kW peak) and compact (fits inside a 19" or larger vehicle rim) direct-drive in-wheel electric motor ever produced, capable of delivering up to 1500Nm of wheel torque instantly. “The bearing is selected as a function of the wheel loads stemming from the vehicle’s weight, its CoG, wheelbase, track width and maximal lateral acceleration achieved during cornering. Order today, ships today. More specifically, we saw a gap in the market for high-performance distributed drives for electric CUVs and SUVs, sedans, pick-up trucks, people-movers and extremely low energy demand vehicles. “That is why our measuring stations have been developed internally from scratch, using a combination of industry-standard hardware and software along with our own improvements, to fulfil in-wheel propulsion system requirements while staying compatible with most other systems. The early results, which can be seen in the short video below, demonstrate that Elaphe’s L1500 in-wheel motor configuration can propel the electrified Audi R8 from 0 … The core innovation in the electromagnetic part was developed in cooperation with the accomplished Slovene physicist, innovator and philosopher Mr. Andrej Detela and is part of a 20 year old vision that has been brought to life by the Elaphe team. With tube prices going out of sight, and availability becoming scarce, this amp is a no brainer. In addition to being able to customise the in-wheel electric motor for carmakers’ preferred brake and bearing suppliers, the L1500’s performance and components can also be tailored to meet manufacturers’ application-specific requirements. Castings and stampings: MWS and other, undisclosed suppliers, Braking components: APG and other, undisclosed suppliers, High Power Media Ltd, Whitfield House, Cheddar Road, Wedmore, BS28 4EJ UK /. This choice is driven by a range of reasons. That keeps them small in size and has some very positive effects in terms of reducing eddy-current losses and their overall mass relative to the magnetic flux.”, Neodymium is used for the L1500’s permanent magnets, a material selection which has also been motivated by the need for high torque density. Lordstown Motors licensed the L1500 in-wheel hub motor from Slovenian tech company Elaphe Propulsion Technologies. WALT machines were originally developed to rapidly test and analyse how wheel components would resist damage over their lifetimes. Elaphe’s approach to such testing is based on the ISO 16750-3:2007 standard for environmental conditions and testing for mechanical loads on electrical and electronic equipment. By running these load simulations in a generative design process (with a constant stiffness target and through a set of proprietary criteria functions), the numerical software can identify all the geometric qualities necessary for minimising structural stress across the metals of the stator and rotor (while also keeping it lightweight and taking manufacturing constraints into account where possible). “In the early years of developing our in-wheel motor technologies, we used mainly N40UH magnets [which have a maximum working temperature of 180 C] in our prototypes in order to ensure good thermal performance,” Gotovac recalls. Loads consisting mainly of vibrations and bending moments can act on the L1500 include those mechanical. Audi, audi cars fit inside a standard 15- or 16-inch rim to what.
