Abstract: In according with the distinctive external rotor structure of hub motor, a functional test bench of hub motor for electric vehicle is designed, including hub motor control system, experiment stand, and measurement & control system. Basic parameters of the hub motor can be measured through adjusting the inputs and loading torque of the motor, such as input voltage/current, input power, motor speed, and output torque. A variety of tests can be implemented to comprehensively test the performance of the motor, such as no-load test, loading test, and efficiency test, which provides data support for the design and optimization of hub motor.
