Mitsubishi Electric plans to commercialize its new EV motor system after finalizing technologies for motor/inverter cooling, further downsizing and additional efficiency.
The cylindrical shape of the power module accommodates parallel cooling ducts for motor and inverter.
Pending patents for the technology number 94 in Japan and 29 abroad.
