Yasa has achieved what it states is the highest power density ever recorded for an electric motor, across any sector or application.
In real-world test trials, Yasa’s prototype motor delivered 550kW of power from a 13.1kg package, equating to 42kW/kg, almost double the previous industry benchmark.
“Last week at Yasa, we believe we unofficially (and a little accidentally!) achieved the highest power density ever recorded for an electric motor in its class (and possibly for any motor),” said Yasa CTO Tim Woolmer in a LinkedIn post on Thursday, July 17.
The milestone was achieved without the use of exotic materials; no cobalt-iron laminations, Litz wire or 3D printing were used. The test saw high-standard thermal performance with a sustained power output. The electric motor has also been designed with mass production potential, which, Yasa says, is scalable to 10,000-50,000 units per year at a viable cost.
The test was completed on a standard rig, and Yasa has said it is preparing for further validation, on a full-capacity dyno, later this year.
