Comparison of Permanent Magnet Linear Synchronous Motor Characteristics Fed by SPWM Inverter and Sinusoid Voltage Source

Abstract

Permanent Magnet Linear Synchronous Motor (PMLSM) characteristics are deteriorated seriously by amount of time and space harmonics, which are arisen respectively from the inverter comprised array switches, the motor teeth-slots and distributed windings. The paper presents field-circuit coupled adaptive time-stepping finite element method to comparison research on PMLSM characteristics fed by SPWM voltage inverter and sinusoid supply. The co-simulation is used with the status space functions and time-step finite element functions. The simulation results of PMLSM fed by SPWM voltage source inverter and S-VS were compared and analyzed.
