Abstract
This article uses the HT32F1765 single-chip microcomputer introduced by Taiwan’s Holtek company as the control core of the system to explore the design of the control circuit and control strategy of the permanent magnet synchronous motor. The main circuit part is the AC-DC-AC frequency conversion main circuit composed of rectification, filtering, inverter, etc., and the control part adopts the regular sampling method to generate spwm waves for control. Finally, the HT32F1765 is used to realize the frequency conversion speed control of the permanent magnet synchronous circuit.
