摘　　要：对交流电机的控制系统进行设计时,设计者往往只关注交流电机和变频器的额定功率,并没有对系统的制动能力进行复核,导致系统因制动能力不足而产生工作异常的问题。论文通过对电机能耗制动机理的分析,为变频器制动电阻的选用及复核提供了一种简单实用的方法。In the design of AC motor control system, the designers usually only concern about the AC motor and inverter capacity. The designers usually do not check the braking capacity of the resistor. The system has abnormal risks because of insufficient of braking ability. This paper provides a simple and practical method for the selection and checking the brake resistor of the inverter.
