Aptera, a startup that's building an ultra-efficient EV, says Elaphe's in-wheel motors offer advantages including enhanced aerodynamics, lower vehicle weight and low energy usage. Its just that none of them are mass-production cars or SUVs. Perhaps an innovative boutique frame brand will be daring and integrate it into a road-going e-bike application soon. He and his team have been working on the dragster and its technologies for the past eight years, and developed many of the parts they used in-house since there was simply nothing on the market. also, it can cover a range of up to 804+ KM ( 500+ miles) on a single full charge. 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. These cookies do not store any personal information. The technology can be easily integrated into existing production vehicle platforms and can help electrify or improve acceleration to the range of todays supercars. BA1 1UA. 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). The larger vehicle is less prone to small variations that affect balance. 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 Merida hub motor is the most powerful electric bike hub motor, and has the best torque and performance. It also comes with an integration of EPB. Ease of integration and component logistics have also been strongly prioritised by Elaphe during its design of the L1500. 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.. With a well-made electric motor from the likes of Bosch or Yamaha, even a 250W motor can deliver. For the utmost effortless journey, you need to install a powerful e-bike conversion kit. Nissan X-Trail e-Power review: Is it better than a Toyota RAV4 Hybrid? 2023 MH Sub I, LLC. The L1500 motor is compatible with all drive layouts rear wheel drive, front wheel drive and four- or more wheel drive vehicles. 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. 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. 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. Since rotors are made mainly from magnetic steel, theyre heavy. #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. On the other end of the scale, some 1,000W bikes have lackluster performance, simply because the batteries or controller were skimped on. Its 6.2-liter supercharged V-8 is the most powerful. L1500 The most powerful compact in-wheel motor ever produced. Developed for the Gemera four-seater, this electric motor, dubbed the Quark, is a tiny powerhouse. Bosch-made in-wheel motors are popular in small electric motor scooters, like those produced by the Chinese brand Niu. 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 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. 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 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. On the chassis, the environmental and structural loads on the inverter are far lower, and it does not contribute any unsprung mass or thermal constraints there, as it would inside the wheel. This is because most electric bicycles are trying to mimic the feeling of a bicycle, which makes total sense.. The stator ring is made from magnetic steel laminations. Also, NVH (noise, vibration and harshness) simulations provide insight into a critical part of inertial load testing. Ive easily hit 40 mph using this motor, and it scared me to death. For magnetic strength, there is always a compromise between the magnet grade and the physical air gap in the motor.. Rising trend. Rotational speed: 1,500 rpm. The Protean Drive. When taking a broad view of the e-bike technology market, it's interesting to note that mountain bikers still have the option on the most potent motor, TQPs HPR 120S. The new Ampere motor weighs less than 10 kg (22 lb) and makes a whopping 220 kW . The Lectric XP 3.0 is a striking e-folder with 3-inch-wide tires on 20-inch wheels and an industrial-styled forged-aluminum frame. Some of the potential areas where we might see the motors turn up include aerospace applications, mining, high-speed rail including hyperloops should the technology eventuate, and yes, even hypercars.

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. This changes the shape of the air gap, which causes vibrations as well as loss of efficiency owing to the increasing resistance to magnetic flux between windings and magnets where the gap widens, and decreasing flux resistance where it shrinks. 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.

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. 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. British company Equipmake has used 3D printing to radically boost power-to-weight figures for its electric motors. Patented and innovative electromagnetic and mechanical designs for in-wheel propulsion enable Elaphe products to be tailored for specific ranges of torque and horsepower to fit most vehicle configurations. So, while in-wheel motors may save some space, their advantage isnt as clear-cut as it might first appear. GM also invested a reported US$75 million in the company. But shoot, aint no one using a 36V battery with this! Then the issues of cost, shock-proofing, brake packaging and unsprung weight also have to be taken into account. To flesh out the ideal design of the housings and motor interfaces, Elaphes technical specialists perform topological optimisations. One, by maximising the cooling surface, we achieve the highest potential torque densities possible. 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.
