Development of Electric Drive Motor for 2009 Model Year Fuel Cell Vehicle

Abstract

A new DC brushless motor has been developed as the electric drive motor for the new fuel cell vehicle. A coaxial configuration was employed for the drive motor and gear box, enabling miniaturization of the drive unit. Owing to optimization of a magnetic circuit, the electric drive motor achieves a maximum power of 100kW, maximum torque of 256 Nm.
The application of the motor has enabled expanding interior space, the dynamci performance equal to 2.4L gasoline vehicle, and increasing curising distance.
