Protean Electric and partners make plans for mass production of in-wheel motors

Protean

In-wheel motor pioneer Protean Electric has announced a collaboration with intelligent mobility specialist Human Horizons and Wuxi Weifu e-Drive Technology (a joint venture formed by Weifu Group and Protean to manufacture the ProteanDrive Pd18) to develop and manufacture in-wheel motors.

The partners plan to build a production facility in China to deliver in-wheel motors at scale.

Ding Lei, Chairman of Human Horizons, called the collaboration “only the beginning of our long-term strategic cooperation. We plan to start with cars and over time develop further innovative mobility solutions. The advanced drive system and the unique location of the in-wheel motor in the vehicle deliver a game-changing driving experience and powerful data collection solution, integrated into the intelligent car.”

“Human Horizons have rich automotive engineering experience and are one of the strongest and most innovative teams in the industry,” said Chen Xuejun, Chairman of Weifu Group. “With more than 30 years of experience working across the industry, Weifu Group has deep experience in auto parts production, continuous manufacturing improvement, mature supply chain resources and the management and delivery of sustained investment in new technologies.”

    You can build all of them you want but they will still suck from too much unsprung weight, cost, low starting torque. They are really only good for low speed E bikes or MCs you can help start with your legs.
    And even then you get a rough ride on the MC.

    Why not give them a chance to proof the contrary before spreading the “old myths” and partially wrong information? At first sight there are in fact many advantages and e.g. PSA/Citroen has developped the perfect damping “Progressive Hydraulic Cushions” and active spring system that certainly also could very well handle any in-wheel designs which at least bring some 30 kg to each wheel. Eventually different tyres and carbon wheels would improve the design too.

    This is interesting to read and clears some prejudices since the beginning which I cannot confirm from a personal ride with an AMG-Mercedes Prototype. But definitely I think it is not the drive for a sports car but for light utilities, delivery trucks, buses etc. and in city cars it will work fine and give more room for passengers by keeping the car very small.

    Unfortunately there are for me other problems, e.g. in the event of an accident there are potentially high repair costs in view and potential electric shock problems may occur. Then the technology must be well protected against water, salt, mud etc. which already for normal wheels and drives is a problem. And also cooling, shocks and vibration are a problem to the components of in-wheel-systems.

    These could work on small shuttle buses for urban areas.
