Abstract: The highefficiency sensorless PMSM system associated with integrated inverter was designed. The system includes highefficiency PMSM motor, DSP control module, inverter module, switch power supply module, current sampling module, wireless communication module based on ZigBee, the host control software. The system has realized the ultraefficient IE4 energy efficiency, and the system has the analog command input and wireless communication module input based on PC, can control the motor start and stop, speed regulation and the direction. The system is stable and reliable, low cost and high performance for the type of fan load. Test results show that the integrated design of motor and controller of the system is reasonable, practical and has high stability.
Key words: integrated; highefficiency; sensorless; FOC; ZigBee; group control
