A Coupling Simulation of Converter Field Circuit for Permanent Magnet Synchronous Motor Based on Simplorer and Maxwell

In this paper, based on Simplorer and Ansoft Maxwell, the field-circuit coupling of permanent magnet synchronous motor converter is simulated. Specifically, a permanent magnet synchronous motor finite element model is created in Maxwell. The principal circuit of the rectifier, the rectifier side control program C module, the main circuit model of the inverter side and the inverse side change control program C module are created in Simplorer. Finally set the lines of magnetic force of the permanent magnet synchronous motor, the flux density, speed, torque based on field oriented control and the SVPWM control strategy. Research shows that applying control strategy based on Simplorer field-circuit coupling joint simulation method combining software and hardware features, the simulation results more close to reality, the integrity of the motor control system for the effective design verification.
