slip loss meaning in English

滑距损失
滑流损失
转差损耗

But because the slipping increasing of this kind of motor is realized by increasing the rotor resistor , it raises the motor ' s slipping loss and cuts down the motor ' s efficiency . the softer the feature of motor is , the lower motor ' s efficiency is
但是由于该种电动机的转差率增大是通过增加转子电阻来实现的，这就增大了电机的滑差损耗，降低了电机的效率，电机特性愈软，效率愈低。
