摘要
Abstract
For the permanent magnet linear synchronous motor (PMLSM) fed by sinusoidal PWM voltage source inverter in the lower speed condition without feedback control, load performance is different from the PMLSM working in high speed region. The paper adopts time-step finite element method and field circuit coupling method to investigate load performance of the PMLSM to drive horizontal transportation system with light load and heavy load condition respectively. It is shown that load performance of the PMLSM in the heavy load condition is highly better than those in light load operation conditions, and operation current becomes lower with load increasing. The validity is verified by comparisons of simulation and experimental results.关键词
