Abstract: Aiming at a direct drive system of a hightorque permanent magnet synchronous motor (PMSM) using for port machineries, the vector control principle of the lowspeed hightorque PMSM was analyzed. Then, the control system with STM32 microcontroller as the core was designed. The STM32 control module, current detection circuits with adjustable gain, resolver interface circuits and the IPM driver and protection circuits were designed and implemented. Finally, the proposed control system was verified with experiments.
