The M700 was the first motor Elaphe fully validated according to existing automotive standards, and both motors have some architectural similarities. US-based Lordstown appears to be the manufacturer closest to production. 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 L1500s permanent magnets, a material selection which has also been motivated by the need for high torque density. An electric motor is an electrical machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. Like the EVs passengers, chassis-mounted motors are protected from lumps and bumps by the suspension, with extra isolation provided by mounting bushings. Perhaps an innovative boutique frame brand will be daring and integrate it into a road-going e-bike application soon. Even with these added components, a chassis-mounted electric motor assembly is a remarkably compact thing. For commuter and touring e-bike riders, often lugging a load or perhaps travelling with a trailer, the TQPs HPR 120S could be ideal. The L1500 D-version in-wheel motor has been optimized for low-volume series production and its earlier versions have been tested on several vehicles including passenger cars and off-road-vehicles. 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. In-wheel motors aren't new. The company is developing their system as the ultimate platform for the future of electric vehicles. The X35+ features ANT+ integration and Bluetooth to connect to Mahle's app. Specialized has invested heavily in a vertical integration of its e-bike sourcing and supply chain. I think Lotus did some research on the unsprung weight issue and concluded it was a matter for good suspension design and not a no-no, but certainly the environment to which an in-wheel is subjected is not great.

At the top of Elaphes in-wheel propulsion product range is the L1500, a radial flux, three-phase AC synchronous motor weighing 33.3 kg, with a radius of 23.2 cm (and therefore fitting a standard 19 in rim) and an axial length of 14.22 cm. The KingSong 18XL is a limited edition version of the KingSong 18L. 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. And two boatbuilders have already . (adsbygoogle = window.adsbygoogle || []).push({}); Surprisingly, the motor is easy enough to install, has a clean form factor, and encourages customization by design. Did I mention you can customize and tune the X1-Pro? The potting material is a custom epoxy resin formula developed to meet requirements such as heat transfer, crack resistance, electrical resistivity, production cycle times and other process-related aspects.. Also, ground-induced or roadinduced loads consisting mainly of vibrations and bending moments can act on the e-motor via the tyre. You also have the option to opt-out of these cookies. If you're buying them new, you find these through local EV parts suppliers - there's a list of US NetGain dealers here. These begin with a vague CAD approximation of each component with a target level of structural stiffness, then repeatedly exposes them to different load simulations, (including differing combinations and quantities of them), over several dozen iterations. Sign up to the E-Mobility Engineering newsletter and stay up-to-date with the fascinating and ever-changing hotbed of innovation. Shimano managed to trim 300g of weight from the EP8000 system, whilst making it 10 per cent smaller, too.

It will match the 3.2 second 0 to 60 mph time of the McLaren F1, one of the fastest cars ever made. The decision to create a set of internal standards for design concepts has also resulted in Elaphe building its own testing centre, which houses machinery to evaluate the endurance and durability of new prototype and customised motors. In-wheel motors are subject to far more impacts and stresses over their lifetime than any e-axle motor, as they are constantly in almost direct contact with the road. Put simply, power is torque multiplied by motor revs and in-wheel motors dont spin very fast. Perhaps the better compromise between one or two chassis mounted motors driving differentials is to use four chassis mounted higher RPM motors with (as you say) 2-cog gears driving each wheel (via CV joints to allow for both steering (at front obviously) and wheel suspension bounce (all four). See Elaphe Christmas video and Happy holidays! the car achieved 3.5 sec 0-100 km/h acceleration time.

But shoot, aint no one using a 36V battery with this! 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. Also, NVH (noise, vibration and harshness) simulations provide insight into a critical part of inertial load testing. It can carry heavy loads and power better than any motor Ive tried off-road. The Elaphe L1500 in-wheel motor achieves the highest torque densities of electric motors on the market, generating 1500 Nm of torque without using any gears. The companies that make the most powerful motors for electric scooters today are Minimotors USA and Rion. Full-scale production should begin in September 2021, and the company says it's holding 100,000 (non-binding) pre-orders for the big double-cab pick-up truck. Lamborghini Urus - 641 Horsepower. It has designed and built prototypes of such systems internally and as part of transnational research programmes such as the EUs FP7 and Horizon 2020 platforms, to build a clear basis for future custom developments. TAX ID: 68995792. In-wheel motors also present the problem of where to put the brakes, which are whats normally found inside a wheel. 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. Power: 50 kW. In recently performed track testing of the L1500 in-wheel powertrain in a modified electric prototype vehicle, the car achieved 3.5 sec 0-100 km/h acceleration time. As a result, there are three high-flex phase cables and two signal cables in the wiring harness for connecting inverters to the L1500. With a dedicated e-bike engineering resource in Switzerland, the strategy is clearly to control its own destiny and pace of development with e-bikes. Elaphe previously showcased prototype mules based on the Smart ForTwo, BMW X6 SUV and Audi R8 platforms, among others, demonstrating proven applications for direct drive, in-wheel propulsion motors. In the end, the supercar's four electric motors deliver a combined 1,470 kW (1,971 horsepower) and 1,254 pound-feet of torque, but the Evija is still recognized as the most powerful EVs in the . All fine in the US but European garages and villages were never designed for these vehicles. The Greyborg frame used a rear hub-motor, so they could leave as much frame space as possible for the battery, and the most powerful rear hub available was the Crystalyte 5-series. As of this writingand likely because we've yet to strap our test gear to an R1T the Ram 1500 TRX is the quickest pickup we've ever tested. The manufacturer has videos and tutorials online, and in print, but honestly, with a bit of bike know-how, the installation isnt hard. On the other end of the scale, some 1,000W bikes have lackluster performance, simply because the batteries or controller were skimped on. Like hairpin stator windings, these can be bent into shapes that forcibly pack the copper back into the ferromagnetic core and minimise the degree of overhang outside of it. Motor size and cost. 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. 8) Speed: 60 - 160km/h The hydraulic disc brakes are a must for high speeds, and the hardtail is a very familiar platform. 7 million for Elaphe Propulsion Technologies as support from the Slovenian government, Prof. Dr Herbert Kohler, Ex-Tesla Board Member & Daimler VP, Joins Advisory Board of Elaphe. With an integrated standard disc brake, a standard outer caliper and a standard hub bearing, it is designed to fit the original vehicle knuckle due to an innovative packaging concept. This isn't the most powerful electric unicycle out there, but if you wish the V8 offered just a little more, the V8F is the better choice. You will receive a verification email shortly. Yamahas engineers applied themselves to improving some of the CEs sound insulation features, lowering its acoustic signature. 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.

Motor and drive electronics are mounted in a single housing, with the battery. If youre curious, were using 21,700 cells, which are more adept at handling a high-amp load. A disadvantage is that instead of sophisticated cadence sensors, the Mahle system requires a torque conversion sensor between the rear hubs rotational speed and cassette motion, to calculate and initiate assistance. With a differential, the motor can power two wheels. There is an alternative, and its the one currently preferred by all mainstream EV manufacturers. Most electric bikes I ride feature a motor in the range of 250W to 1,000W. Excess preloading from manufacturing, introduced mostly during machining and casting, can also cause residual internal stresses to build up in motor designs before they are tested. Our insights and models for e-motor optimisation are part of our proprietary knowhow, Lampic adds. To demonstrate the performance, HyperPower teamed up with electric drag racers Top EV Racing and built a Top Fuel-style dragster powered by four of the motors for a combined output of 5,360 hp. The system is configured as a directdrive outrunner (meaning it has an external rotor and an internal stator). Likes the BMW i3, but it's just too damned wide An excellent analysis of in-wheel motor pros and cons, John. The big advantage of Evations system is that you can remove most of it, reducing weight and rendering your e-bike close to the configuration of a conventional bike.

Listed by Car and Driver magazine as one of the ten most promising technologies for 2013, the Protean Drive is a 75-pound electric motor that generates 100 horsepower and 735 lb-ft of peak torque. The L1500 motor is compatible with all drive layouts rear wheel drive, front wheel drive and four- or more wheel drive vehicles. That would probably have reduced the rate of adoption, owing to the higher initial price point. Max power: 9.6 kW. Scalability of the companys design processes has been critical for conceiving the structural architecture of each new L1500. Founded in 2003, Elaphe Propulsion Technologies Ltd. is a leading EU-based developer and manufacturer of in-wheel electric propulsion systems for electric and hybrid vehicles. Bosch-made in-wheel motors are popular in small electric motor scooters, like those produced by the Chinese brand Niu. 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.. Peak power is an average 55Nm, which isn't a lot, but it is marketed at riders with adequate fitness who want to ride further, in less time, instead of those cyclists who require a lot of pedal-assistance all of the time. Thermal sensors are added to the bearing hub during these tests to measure any overheating. If you can use an uninterrupted, continuous wire instead of so many separate pieces, you dont need so much insulation, and its more cost effective to manufacture. A unique packaging philosophy without displacing existing packaging and brake architecture. Having electric motors instead of gasoline-powered engines makes Teslas able to accelerate far quicker than most standard cars. Weve analysed most of the leading electric power units available in most contemporary road, gravel and commuter e-bikes. 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. One of the most powerful mid-drive motors on the market, the Ultra can produce 1,000W of nominal power, which is over the street legal limit. Their most powerful models ( Dualtron X2, Rion2 RE90) use proprietary motors that have power levels in the thousands of Watts. And, its dual motors gives it more power than most electric scooters its size. Until today, the world's most powerful production car was the all-electric Rimac C_Two, which makes a puny 1,914 horsepower. The Endurance has The Worlds First All-Electric In-Wheel Drive System Built For Work, according to the capital-letter enthusiasts in the Lordstown marketing department. At 637 horsepower in launch control mode, Audi says that the RS e-tron GT is the most powerful vehicle they've ever produced, gas or electric. Its 35Nm power output might not be enough for unfit riders who wish to power up the steepest road climbs and retain range, but for fit riders, it is ideal. ANT+ and Bluetooth connectivity with Mahle app for smart features, Used by some of the biggest names in cycling, Adds weight to the rear of the bike and not just the middle, Claimed to be the quietest motor on the market, Incredibly quiet compared to the competition, Not as powerful as other mid-drive motors, A lightweight low-power motor that's ideal for fit riders, A tiny motor to give your ride a little extra oomph, The long-awaited e-bike system from the lightweight composite specialist, Updated motor from Shimano is full of features and full of power, We check over 250 million products every day for the best prices, E-bike motors can either be in the rear hub or mostly, the bottom bracket. The result is a compact mid-drive motor that delivers 50Nm of torque output, which is entirely adequate for any inner-city gradient you might have to ride up. There should be heaps of bonnet space after chucking out the ICE and all its 20th century stuff, but OK perhaps the boot/trunk space might suffer a bit. In parallel with the high-torque requirement, weve constructed them in a way that avoids resonant frequencies when testing motors at very high speeds. So while its a little harder for some of the wire to transfer heat to the liquid circuit, the net effect is that you end up with a cooler stator during operations. Where FSA deserves credit, is equipping the motor with a diversity of output sensors: including one for torque and two for speed. 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. TOP 10 MOST POWERFUL ELECTRIC BIKES IN THE WORLDAre you looking for the most powerful electric mountain bikes of 2021? This is because most electric bicycles are trying to mimic the feeling of a bicycle, which makes total sense. Fazua has been engineering mid-drive motors since 2013 and it understands the issues around frame integration. Lightyears efficiency-obsessed engineers designed the motor used in the Ones wheels from scratch. Rory Jackson reports on how it was developed. For the utmost effortless journey, you need to install a powerful e-bike conversion kit. The larger vehicle is less prone to small variations that affect balance. 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). Engineers have managed to do what all riders desire from their mid-drive motors, be lighter and more powerful. But some companies are working on a radical redesign, placing motors . Yamaha has five support mode options with the PW-X offering 320% support in the EXPW mode. As well as being useful for testing tyres and rims, they are also designed for studying bearings in a fast, repeatable and controlled manner, which is ideal for the L1500. Hydrogen electric vehicles, often called hydrogen fuel cells vehicles (FCEV), drive the same as regular EVs. This makes upgrading your mid-drive motor, even within the same brand, rather difficult. GM also invested a reported US$75 million in the company.

It also has to adhere to tilting stiffness conditions, Gotovac says. READ MORE: Full electric car advice and FAQREAD MORE: EV tech explained. With a mid-drive motor, you are stuck with what you have. Other proprietary innovations have been developed to help balance the voltages between parallel branches in each phase, to accelerate automated production of large volumes of copper (while packing them more densely), and to make the winding more robust against high temperature gradients not just extremes of temperature, but rapid changes in short periods of time. Specifically the 5404, 5405, and 5406, which have large 40mm wide stators and magnets. The Elaphe M700 motor is an extremely compact high-torque in- wheel motor, designed to fit inside a standard 15- or 16-inch rim. It is a very responsive system and also includes a power cut off brake system which is a good feature . Basically, they add to the weight that has to be controlled by the suspension systems shock absorbers. Thoughtful article John. The equipment enables rapid iterations and confirmations of product designs, although the company also cooperates with various institutions around the world for impartial third-party validations and to complement its own efforts. At the same time in-wheel motors reduce vehicle part count, complexity and cost. Rising trend. Elaphe L1500D motor features unique compact packaging around standard knuckles and friction braking systems. To that end, Elaphe has used heat treatments to minimise these loads and their effects on structural components. The FSA System HM 1.0 is an integrated approach. All rights reserved. All three are immediately recognisable cycling frame brands and they share a common specification thread: the use of Mahle e-bike technology. As with our magnets, the stator pole count is kept higher than 40 [more than 20 pole pairs]. 4) Voltage Range: 72V, 84V, 96V, 108V, 120V. Subscribe to our weekly newsletter! Full-scale production should begin in September 2021, and the company says its holding 100,000 (non-binding) pre-orders for the big double-cab pick-up truck. It's a great mid-range wheel with a price to match. Its what we call our multiphysics approach, says Lampic. In-wheel motor technology offers a fresh solution by providing power that can meet and exceed internal combustion engine alternatives in a package that does not invade chassis, passenger or cargo space. I understand that I can unsubscribe at any time. With the advent of start-stop technology and mild hybrid vehicles, the starter motor is morphing into the starter-generator, and taking on more functions. Installation: 14-50 plug. These motors power the wheel directly. MSRP: $750. The controller is integrated inside, as well as a torque sensor that is enclosed in the bottom bracket. The conductor bands can have a round or square cross-section, as well as a tangential shape to u-bend around each stator tooth to the next, with at least one continuous band per phase of the motor (unlike the many separate bands used in hairpin stators). And, with a powerful rear-wheel drive 350-Watt motor and large 10-inch inflatable tires, the . Which flux type are our motors radial or axial flux? Elaphes in-house winding machines are optimised to apply each subsequent phase of copper with the appropriate force to insert and compact the bands into the stator slots as deep as necessary for the desired packing density and uniformity, without scratching or breaking them. 17inch 12KW Hub Motor 1) Motor Type: DC Brushless Motor. Second, the cooling system is positioned in such a way that it also intrinsically shields the electromagnetic part from heat transfer from the brakes.. 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. Protean's PD18 has a crucial advantage over other in-wheel motors - it can be retrofitted to existing vehicles. The Swedish hypercar outfit has unveiled the mighty mite as locomotion that will help drive its plug-in hybrid Gemera sedan. The 5-series motors are very large, and they are also very heavy.

Ive easily hit 40 mph using this motor, and it scared me to death. 12 Photos. Yamaha also claims that its CE is the quietest running mid-drive motor it has ever produced, and that means you can use all the pedal-assistance power available, without ever feeling guilty about producing too much electromechanical noise. Not having a locked-in inverter also opens up the possibility for reducing costs on a powertrain-wide level. Both Lightyear and Lordstown stress the benefits of in-wheel motors. Control Electronics Design and Validation, The L1500 motor is compatible with all drive layouts. The technology can be easily integrated into existing production vehicle platforms and can help electrify or improve acceleration to the range of todays supercars. One, by maximising the cooling surface, we achieve the highest potential torque densities possible. To minimise the effects on the air gap, the bearing must be able to sustain sufficient external loads to prevent them passing through to the rotor and stator. He's now established HyperPower in order to commercialize some of those developments. 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. Tesla's most powerful electric Cybertruck comes with triple motor all-wheel drive. Then there are practical problems. You get a larger wheel without losing portability.
