Thank you for signing up to The Pick. 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. This has two critical benefits. An Australian company by the name of HyperPower Technologies has developed an electric motor that generates a mammoth 1,340 horsepower. Subscribe to Electrek on YouTube for exclusive videos and subscribe to the podcast. Add to this the fact that the entire operation is on 2-inch-wide tires, and available roads for this kind of testing arent freeway smooth. These are some of the fastest e-bikes . While theres still some way to go in terms of common, smart standards for inwheel motor development, over the past 20 years weve created a set of internal standards based on our tools, methodologies and various industry best practices.. While we can use MOSFETs, IGBTs, SiCs and GaNs, weve found that the L1500 is most popularly paired with a COTS silicon IGBT inverter with a 200 kVA maximum output, installed on board the vehicle, Gotovac says.

An additional feature is the Automatic Support Mode, designed to respond to changing conditions and automatically choosing the most appropriate mode for your ride. In relative terms, far fewer wire connections need to be made, which improves consistency of quality, reliability and production costs. As Lampic says, We wanted to bring what we feel is required for improving future OEM EV/HEV models. The installation of the motor was not nearly as hard as I expected. We cant know for certain whether silicon IGBTs, SiC or some other transistor will become the standard. 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. Frames are also specifically designed with the cooling properties and packaging of a specific source mid-drive motor. 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. In a package that weighs just 63 pounds, the Quark develops 335 hp and 443 lb-ft of torque. For instance, even in a 200 kW test system it is unlikely that a 60 kW in-wheel motor could be tested at its rated or peak torque, because of how a suppliers test benches are built and their corresponding torque-sensing limitations. Elaphes 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. As a result, the active part of the motor the electric machine with windings and magnets takes up just 30% of the overall weight, giving it a torque density of 460 Nm/litre, compared with what the company cites as its nearest competitor at 390 Nm/ litre. Has written about cars and the car business for more than 35 years, working full-time and freelance for leading mags, major newspapers and websites in Australia and (sometimes) overseas. Founded in 2018, the start-ups plant in Lordstown, Ohio, was bought from General Motors. This gets a bit complicated, so pay attention. 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. Protean CEO Andrew Whitehead and Chief Commercial Officer Ben Boycott sit down with Auto Futures to speak about the development of the world leader of in-whe. The latest race content, interviews, features, reviews and expert buying guides, direct to your inbox! There are three e-bike classes (Class 4 is for mopeds, scooters, or an electric bike motor with 1000w+). If youre curious, were using 21,700 cells, which are more adept at handling a high-amp load. Rad Power Bikes' RadRunner Plus is a 20-inch fat tire mini folding electric bike packed full of features and power, enough to take on any job you need. 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. Lightyears efficiency-obsessed engineers designed the motor used in the Ones wheels from scratch. KingSong 18XL Buy now on E-Wheels Weight: 53 lbs Speed: 31 MPH Wheel Size: 18" Carrying Capacity: 325 lbs KingSong is a pioneer in making some of the best electric unicycles in the business. Also, it is generally similar, but not the same, as the battery electrical "horsepower" output. Did I mention you can customize and tune the X1-Pro? Thats also helped refi ne our proprietary processes for how to make the windings as short as possible.. At the beginning of the 20th century, Ferdinand Porsche's first hybrid vehicle used hub-mounted electric motors in each wheel. the car achieved 3.5 sec 0-100 km/h acceleration time. From golf cars to ocean liners with electric drives you will see both of the basic options - synchronous and asynchronous (induction). In recently performed track testing of the L1500 in-wheel powertrain in a modified electric prototype vehicle, Images related to this article can be found at. bafang-e.com. While normal bearing deformations arent a major problem, excessive deformations in an in-wheel motor can cause deflections between the rotor and stator. Additional simulations of external loads on the L1500, such as those coming from hitting potholes, curbs or other issues related with rough roads, were performed according to SAE standards including SAE J175 and J1981 on impact tests for wheels and tyres in road vehicles. Add it all up, and its not hard to understand why EVs dont have in-wheel motors. Class 3 - Max assisted speed of 28mph, with or without a throttle. With a differential, the motor can power two wheels. In addition to being able to customise the in-wheel electric motor for carmakers preferred brake and bearing suppliers, the L1500s performance and components can also be tailored to meet manufacturers application-specific requirements. The ideal candidate will be a $400 mountain bike with 26 inch wheels and cable pull disc brakes. The stator ring is made from magnetic steel laminations. 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. Once these tests confirm that the motor components undergo no damage, and experience no stator-rotor contact in the air gap (and that the bearing never overheats or reaches temperatures indicative of damage), the customer-preferred bearing can be integrated into the L1500. Thoughtful article John. You also have the option to opt-out of these cookies. Future Publishing Limited Quay House, The Ambury, The RadRunner Plus is a Class 3 bike because of the 750W/80Nm motor with throttle operation and 28mph max speed on pedal assist mode. That maximises the surface area under which our cooling channels can run, as close as possible to as much of the copper as possible, Gotovac says. . Since rotors are made mainly from magnetic steel, theyre heavy. Even with these added components, a chassis-mounted electric motor assembly is a remarkably compact thing. Most electric bikes I ride feature a motor in the range of 250W to 1,000W. 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. 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. 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.. The M700 was the first motor Elaphe fully validated according to existing automotive standards, and both motors have some architectural similarities. 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). Cable length/diameter: 18.7 ft/0.6 in. Volvo Construction Equipment. 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. Yamahas engineers applied themselves to improving some of the CEs sound insulation features, lowering its acoustic signature. Off road, this is a billy goat. Those standards have also informed our requirements for e-motor and inverter-specifi c performance parameters, EMC, electrical safety, durability and cable routing. 17inch 12KW Hub Motor 1) Motor Type: DC Brushless Motor. 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. Opting for the hub-drive motor option, FSAs complete e-bike system weighs 3.98kg. And in-wheel motors tend to be heavy things. They can have one, on iPhone maker Foxconns Android open-source EV platform, on Why burning hydrogen in an ICE is an awful idea, on VIDEO: Why the 4S is all the Porsche Taycan you need, on FCEV: Fuel cell hydrogen electric vehicle, on EV or BEV: Electric vehicle or battery electric vehicle, New Tesla Model Y coming in 2024: reports, RAM 1500 electric pick-up goes from wild to mild, Chinas Geely enlists star power for new electric brand. Our method means maybe only 24 welds or so are needed for each L1500 stator.. Media and interview requests can be directed to:Elaphe media contact, Luka Ambrozicpress@elaphe-ev.comWebsite:www.in-wheel.comMedia gallery:https://in-wheel.com/media-gallery/all/, Teslova 30 The Cargo Line is one of the newer Bosch mid-drive motors and has some tidy upgrades. I understand that I can unsubscribe at any time. 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. To that end, Elaphe has used heat treatments to minimise these loads and their effects on structural components. Which flux type are our motors radial or axial flux? 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. . In addition to having produced various motor mechanical layouts, Elaphe has also developed, tested and integrated its own motor inverters. Wayne Ward reports. 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.. In other EV news, British company Equipmake has developed what it claims is the worlds most power-dense permanent magnet electric motor. The company's Ampere motor weighs just 22 pounds but develops close to 300 hp. As a result, Elaphes development models encompass an extensive number of studies, simulations and tests, to iterate a motor that will withstand a broad spectrum of loads over its lifetime. 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. Rider research showed that Boschs engineers had to improve the low-speed cadence matching of their Cargo Line motors. Maybe Lordstown, Lightyear and others will change the situation, but it seems unlikely theyll change the minds of manufacturers using chassis-mounted motors with reduction gears and differentials. But shoot, aint no one using a 36V battery with this! The company, based in Europe, provides customized and OEM-ready in-wheel powertrain solutions for a wide range of vehicles. Their compact and scalable design allows for the use of standard brakes and bearings with the in-wheel propulsion system. Youre an adult, you can figure this out for yourself. The L1500 motor is compatible with all drive layouts rear wheel drive, front wheel drive and four- or more wheel drive vehicles. For example, thermo-mechanical simulations are carried out to examine how the air gap between the rotor and stator might deform as a result of severe heat and shock. The advantage, compared with hairpin stators, is that our overhangs are much shorter, meaning less losses, Gotovac says. It also comes with an integration of EPB. If you're buying them new, you find these through local EV parts suppliers - there's a list of US NetGain dealers here. Tests on the L1500 include those for mechanical shocks. A Bafang Ultra mid-drive motor on a QuietKat JEEP all-terrain electric fat bike. It also has a torque-to-weight ratio of 100 Nm/kg; its competitors go up to 65 Nm/kg, Elaphe says. 37" x 18" x 28". I agree to receive emails from Motor Authority. Check latest price on E-Wheels 2. Its capacity surpassed the Navy's previous test record, doubling the rating. The exact grade of neodymium in each L1500 depends on parameters related to cost optimisation and application-specific development, among others, adds Gotovac. Ive got it equipped on a Specialized hardtail. For one, the company has observed that the market for in-wheel motors has very diverse requirements, with many different vehicles and value propositions. The top-end speed of most Tesla models might not be as high as gas-powered vehicles, but they'll get you there much faster thanks to the instant torque provided by the electric motor (s) and simple transmissions. High cadence and torque outputs can increase the risk of overheating a mid-drive motor. For all the benefits of e-bikes, they can also create confusion and ownership anxiety, triggered by the steep technology curve powering these bikes along. Elaphe L1500 in-wheel motor Applications for the L1500 in-wheel motor include Sportscars (above), pick-up trucks, SUVs and urban vehicles (right), among others (Images courtesy of Elaphe Propulsion Technologies) Fit for duty The L1500 has been designed to enable it to be used in a wide range of OEM EVs and HEVs. 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). This limits the bikes that can be converted with it. It might be a touch too powerful for some road and gravel riding applications, but its size and shape could become a reference standard. 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. The L1500 motors are therefore simply inserted between the electric [or hybrid] vehicles hubs and rims, which makes use of the existing space within the wheel without needing to alter any suspension or steering packaging on the platform, explains Elaphes CTO Gorazd Gotovac. British company Equipmake has used 3D printing to radically boost power-to-weight figures for its electric motors. Keen to control the convergence of batteries, drive motor efficiency and pedal-assistance sensitivity, FSA has developed its own 250Wh lithium-ion energy source and control units. Bath 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.. In our standard, publicly known solutions, we construct the rotor with surface-mounted permanent magnets, although we are familiar with other ways of designing and installing the magnets if the application or customer requires their use, Gotovac says. In terms of ride feel, the PW CE delivers a natural-feeling ride. The motors are lightweight, easy to install, and provide smooth gear shifting. Something of the new kid on the block in the world of . The KingSong 18XL is a limited edition version of the KingSong 18L. Bosch released a new software update for 2021 to address this, giving more support at low cadences making it easier to set off or ride slowly when carrying heavy loads. 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 Elaphe in-wheel powertrain platform includes motors, power electronics and intelligent multiple-motor propulsion control. At a nominal voltage input of 370 V, its maximum power output is 113.6 kW (at a speed of 1480 rpm), as well as a maximum tested torque of 1500 Nm. In comparison, the two electric motors used in Jaguar's I-Pace weigh 88 pounds each and deliver just 200 hp. Lamborghini Urus - 641 Horsepower. 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. That's right - even more power than the V10 R8.. Several suppliers, including Elaphe, Protean and Nidec, have developed in-wheel motors. This is vital, as the development of robust in-wheel electric motors encompasses a far broader set of targets than simply achieving the optimum magnetic fluxes, inductances and other typical electric motor parameters. Then there are practical problems. 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. Sign up to the E-Mobility Engineering newsletter and stay up-to-date with the fascinating and ever-changing hotbed of innovation. The Most Powerful Electric Motor in the World A high temperature superconductor (HTS) developed by Northrop Grumman Corporation and tested by the U.S. Navy holds this title. Cost is one of them. The L1500 has been designed to enable it to be used in a wide range of OEM EVs and HEVs. A key challenge with in-wheel motors is how to deal with temperature gradients, Gotovac explains. It will match the 3.2 second 0 to 60 mph time of the McLaren F1, one of the fastest cars ever made. The best e-bike motors will balance the scales between power and weight, to offer maximum pedal assistance without weighing the bike down and holding it back. And two boatbuilders have already . Subscribe to our weekly newsletter! It also comes with an integration of EPB. Riding this fast is indeed scary and thrilling, but oddly enough, I somehow feel safer using the X1-Pro motor, because I know its made for high speeds.
