摘　　要：交流电动机的串级调速是一种将绕线式异步电动机的转差功率利用起来的一种高效、经济的调速方法。它可以把转差率转变为机械功率反馈回电动机机械轴上,或把转差功率反馈至交流电网中,使得具有良好的调速性能和较好的功率利用性。本文研究的是异步电动机串级调速的原理以及串级调速的机械特性。The cascade speed regulation for AC motor can effectively and economically utilize the slip power of wound rotor asynchronous moter to regulate the speed. It transfers the slip power to mechanical power and then feed the power back to the shaft of the motor, or directly feeds the slip power to the alternating current net, so as to ensure the speed regulation a higher performance and higher power utilization ratio. The principle and mechanical properties of such speed regulation is discussed is this paper.
