摘要
异步电机转子导条和端环的故障会加大鼠笼中的热应力,这会导致电机的功率损耗或者引起电机颠覆。介绍的新方法能够及时发现这种故障,从而提高驱动系统的可靠性并避免停机所造成的较大损失。
Faulty rotor bars or end rings cause additional thermal stress in the squirrel cage of asynchronous machines. This leads to performance loss or breakdown of the motor. A new method allows early detection of such faults and thus increases reliability of drives and avoids expensive downtimes.
