As Lampic says, We wanted to bring what we feel is required for improving future OEM EV/HEV models. 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. 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. This Slovenian outfit has a licensing agreement with Lordstown. There is no tightening or straining of them, as might happen with copper strands, or any post-deformation as with hairpin stator conductors. As these overhangs lie outside the stator slots, they do not contribute to motor torque. Available and refined since 2017, the latest upgrade of this rear hub motor launched in late 2020. 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. Their most powerful models ( Dualtron X2, Rion2 RE90) use proprietary motors that have power levels in the thousands of Watts. 2) Motor Version: V4. Electric motors are much more efficient at driving wheels than internal-combustion engines, and in the case of Top Fuel dragsters, the cars running over 5,000 hp are slipping the clutch for half their runs, according to Fragomeni, meaning they're not using the full power they're making. The Lohner-Porsche electric car of 1901 used in-wheel electric motors The Lordstown factory is building pre-production versions of its first model, the Endurance ute. 750W Utility eBike. An OEM in collaboration with Elaphe can select their preferred bearing that fits within these parameters and most existing OEMs and suppliers produce bearings that are suitable.. Fazua has been engineering mid-drive motors since 2013 and it understands the issues around frame integration. At that power level, this bike is designed for private land or OHV areas. As with most things in cycling, the issue is differing standards. The J+ Booster 2 can be used as both a home charging station and a mobile charging cord, making it a . From here you can record trips, analyse a multitude of real-time data, view maintenance requirements, and make use of the antitheft protection. Accurate torque and speed data enables an e-bikes control algorithm to deliver a natural feel, when matching your cadence with some additional watts. 6) Wheel Size: 17 x 6.0 inch (Aluminum Wheel) 7) Recommendation Tyre: 180/55-17 to 220/70-17. With the SL 1.1 motor, Specialized has shown how light a high-performance road e-bike can be. While normal bearing deformations arent a major problem, excessive deformations in an in-wheel motor can cause deflections between the rotor and stator. 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. Sign up to the E-Mobility Engineering newsletter and stay up-to-date with the fascinating and ever-changing hotbed of innovation.

READ MORE: Full electric car advice and FAQREAD MORE: EV tech explained. 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. FSA is renowned for its lightweight composite components but the company has invested meaningfully in e-bike motors, too. It might be considered too powerful for road use, but that logic discounts the abundance of traction that road and commuter bikes have, on a high-friction surface, compared to mountain bikes, riding up loose climbs. Elaphe L1500D motor features unique compact packaging around standard knuckles and friction braking systems. As a result, all wheel integrations using the motor will also incorporate standard, off-the-shelf automotive bearings and braking systems (of which a range exists), including standardised brake rotors, calipers and electronic parking brakes. Privacy Policy. 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. It might weigh less and be more compact, enabling better frame integration, but the Shimano EP8 is 10Nm more potent than its EP8000 predecessor, delivering 85Nm of output. Future Publishing Limited Quay House, The Ambury, Sign up to get the latest performance and luxury automotive news, delivered to your inbox daily! A traditional friction brake, with a disc rotor and caliper, fits inside the stator ring and attaches to the hub, as in all cars these days. But some companies are working on a radical redesign, placing motors . The only limitation is me, the rider. The all-new Storm 300+ is a big, brawny outboard motor with over 300 horsepower of continuous power, making it the world's most powerful electric outboard motor. The technology also integrates seamlessly with autonomous driving applications, providing feedback data, unprecedented responsiveness and enhanced vehicle controllability.. The KingSong 18XL is a limited edition version of the KingSong 18L. There was a problem. The Lohner-Porsche petrol-electric hybrid of 1900, for example, was powered by electric motors built into the hubs of its big, balloon-tyred wheels. The heat transfer coefficient of copper is better than any of the other materials in the motor, so the more copper, the better the thermal efficiency and the lower the heat losses. About Elaphe Propulsion Technologies Home > Features > Elaphe L1500 in-wheel motor. The performance of an overclocked motor doesnt feel that much better than this stock version of the X1-Pro. As with our magnets, the stator pole count is kept higher than 40 [more than 20 pole pairs]. But with so many options on the market, it can take time to figure out where to start. With a well-made electric motor from the likes of Bosch or Yamaha, even a 250W motor can deliver. 12 Photos. The bearing is selected as a function of the wheel loads stemming from the vehicles weight, its CoG, wheelbase, track width and maximal lateral acceleration achieved during cornering. Starter motors are still typically the most powerful electric motors other than traction motors. 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). Stock photography by. Cars on the road expect motorcycles to be fast and loud, and they have bigger lights and safety features. The electric motor, code-named the QFM-360-X, measures about 17 inches in diameter and is designed to be scalable. You also have the option to opt-out of these cookies. And Im also adding a throttle into this review. This inescapable relationship means in-wheel motors need big rotors to make enough power to deliver customer-satisfying performance. The newer second-generation e-bike motors are smaller, which would require custom adaptor plates to fit them to an older frame. Having been filtered through the industrial designers guidelines, the stator and rotor designs are then evaluated (together with connected structural interfaces for a holistic motor simulation) using multiphysics finite element analysis (FEA) testing. It would be challenging to swap between Bosch and Yamaha, for instance, due to different proportions. The installation of the motor was not nearly as hard as I expected. Likes the BMW i3, but it's just too damned wide An excellent analysis of in-wheel motor pros and cons, John. This motor is the culmination of my careers effort and a notable milestone for our team to now have the (motor) in production, with volume assembly running in parallel, he said. I capped it out at 72V, but I also used a 52V battery to get to my racing destination at an empty track nearby. It is a very responsive system and also includes a power cut off brake system which is a good feature . It also comes with an integration of EPB. 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. Add it all up, and its not hard to understand why EVs dont have in-wheel motors. 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. #2 Addmotor Motan Electric Trike #3 DWMEIGI Adult Electric Trike #4 Liberty Electric Trike #5 Emojo Caddy Pro Electric Trike #6 MotoTec Electric Trike #7 Toxozers Electric Trike #8 Fat. It is the strongest hub motor available, and can convert any bike into an electric bike. Visit our corporate site (opens in new tab). TAX ID: 68995792. The technology can be easily integrated into existing production vehicle platforms and can help electrify or improve acceleration to the range of todays supercars. The Cargo Line is one of the newer Bosch mid-drive motors and has some tidy upgrades. The company has software scenarios (and dedicated test tracks, which would be used for road-proving the motor later on) for driving over potholes, brick roads, speed bumps, embedded rock paths and other surfaces to examine how the motor handles the repeated impacts and harmonic stresses of such use. LEITNER and Elaphe on Connx: intensive testing and development phase as a major step towards market readiness, Elaphe on DREEM e-motor design and prototype tests, Aptera and Elaphe ink deal for scale production, Elaphe and Lightyear develop the most efficient production powertrain in the world, The fat ballerina on winter testing grounds, ASTRABAT applies certifications to all-solid-state battery prototype. The motors aluminium rotor case contains the yoke and permanent magnets, the case wraps around the stator, and is connected to the vehicle knuckle by a conventional automotive wheel hub bearing. 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. 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. 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.
