摘　　要：常规游梁抽油机配备传统异步电机,运行时电机平均负载率不足30%,“大马拉小车”现象较突出,造成电能浪费大。稀土永磁同步电机具有平均运行效率高、功率因数高、启动力矩大、过载能力强、高效节能等特点,通过在抽油机上试用和批量使用,达到了良好的节能效果,可替代目前在抽油机上使用的异步电机。Conventional beam puping unit is equipped with normal asynchronous motor and its average load is less than 30%,“strong horse drawing small cart”causing the waste of energy.The rare earth permanent magnet synchronic motor has even operation effectiveness,high cosine,high starting torque,high over loading capability and energy saving.The experiment and application on beam pumping unit show better energy saving,which is the ideal replacement for conventional motor.
