Abstract

This paper introduces the design and implementation of hardware circuit of permanent magnet synchronous motor Servo Controller Based on DSP.In this scheme,TMS320F28335 is used as the control core, and drv8312 is used as the three-phase motor driver chip. The main control circuit, communication circuit, drive circuit, current feedback circuit and protection circuit are designed in detail. The reliability of the control circuit is verified by experiments, and the servo control of PMSM is realized.
