A reciprocal power-fed experimental system based on id=0 vector control is designed, which includes a double “Inverter-PMSM” and one incremental encoder.The construction and working principle of this system are discussed,then the hardware structure of the system is introduced and the soft of the experimental system is developed. The experimental results indicate that this experiment system has excellent dynamic and static performances and high control effect,which can be used in research of the control of the permanent magnet synchronous motor.
