The air compressor is indispensable key equipment in the industrial production process. The permanent magnet synchronous motor is the core component of the air compressor. Optimizing the control technology of the motor can effectively improve the operation efficiency of the air compressor. Permanent magnet synchronous motor is studied. This paper analyzes the air compressor load, establishes a permanent magnet synchronous motor model, and adopts PI speed loop and PI current loop vector control. The simulation analysis is carried out by inputting the load torque and the reference speed. The results show that the motor vector control effect of this paper is better, and the motor speed and torque can be output stably when the load torque of the air compressor fluctuates.
