Abstract
Built-in permanent magnet synchronous motors (PMSM) are widely used in social life due to their strong load capacity and high-performance speed regulation ability. This paper derives the equation conversion of PMSM from abc coordinate system to dq coordinate system, introduces the basic principle of the Maximum Torque Per Ampere (MTPA), and builds a simulation model based on the MTPA vector control system using MATLAB/SIMULINK, analyzes the changing law of the simulated waveform.
