变频器制动电阻的选择 在变频调速系统中，电机的降速和停机是通过逐渐减小频率来实现的，在频率减小的瞬间，电机的同步转速随之下降，而由于机械惯性的原因，电机的转子转速未变。当同步转速小于转子转速时，转子电流的相位几乎改变了180度，电机从电动状态变为发电状态;与此同时，电机轴上的转矩变成了制动转矩，使电机的转速迅速下降，电机处于再生制动状态。电机再生的电能经续流二极管全波整流后反馈到直流电路。由于直流电路的电能无法通过整流桥回馈到电网，仅靠变频器本身的电容吸收，虽然其他部分能消耗电能，但电容仍有短时间的电荷堆积，形成“泵升电压”，使直流电压升高。过高的直流电压将使各部分器件受到损害。因此，对于负载处于发电制动状态中必须采取必需的措施处理这部分再生能量。处理再生能量的方法：能耗制动和回馈制动. 能耗制动的工作方式 能耗制动采用的方法是在变频器直流侧加放电电阻单元组件，将再生电能消耗在功率电阻上来实现制动。这是一种处理再生能量的直接的办法，它是将再生能量通过专门的能耗制动电路消耗在电阻上，转化为热能，因此又被称为“电阻制动”，它包括制动单元和制动电阻二部分。
