摘要
文章对比三相异步电动机的电枢电流轨迹图,通过分析稀土永磁同步电机的运行状态和矢量图,仿真了该电机的电枢电流轨迹图,得出电网电压波动对稀土永磁同步电机的带载能力和功率因数的影响,仿真结果在一台油田抽油用37kW的6极稀土永磁同步电机上得到验证。
This paper makes a contrast between the armature current of asynchronous motors and the rare earth permanent magnet synchronous machines (REPMSM), through analyzing the phasor diagram and the running state of REPMSM, emulating the armature current of REPMSM, gets the effect of network voltage on power factor and load ability, and the result is proofed on the six poles, 37kW rare earth permanent magnet synchronous machine used in oil fields.
