摘要
分析三相凸极式同步电动机异步起动过程中的谐波电流和冲击电流及其产生的原因。并用MAT- LAB进行了仿真,得到各电流波形,这些电流形成的转矩严重影响电机的起动性能。为此,提出了一些改善电机起动性能的措施。
The paper analyzed the harmonic and impulse currents as well as their causation, during the start-up process of a three phase salient pole synchronous motor. The torque produced by these electric currents, which were simulated by Matlab influenced the start-up of the motor greatly, Some measures for improving starting properties were given out.
