Abstract A new DC brushless motor has been developed as the electric drive motor for the Honda FCX Clarity 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 100 kW, maximum torque of 256 Nm. The application of the motor has enabled expanding interior space, the dynamic performance equal to 2.4 L gasoline vehicle, and increasing cruising distance. JSAE Paper No 20095396
