Abstract

Compared with traditional motor, permanent magnet synchronous motor has the characteristics of strong anti-interference ability, high starting torque and power density, and good speed regulation performance.Permanent magnet synchronous motor servo system has become a research hotspot in the field of servo drive.In this paper, with DSP28335 as the main control chip to give a permanent magnet synchronous motor AC servo control hardware system design scheme, the paper introduces in detail the system core control circuit, main power circuit, detection circuit design and the choice of main components.The hardware system designed has been applied to engineering practice, and has achieved good control effect.
