摘　　要：通过一个实例。介绍了电梯的专用变频器的容量和制动电阻的计算方法。经过分析指出；变频器的选用不能只考虑适配电动机的功率。还应考虑变频器的制动功率和制动电阻阻值的合理选择。否则。变频器直流母线过电压的现象将影响电梯在制动状态的正常运行。Taking an example, this paper introduces the calculation method of the apaoity of inverter and its braking resistor. The author finds in some working conditions, the selection of frequency converter for use not only consider the adaptation of the motor power, but also should consider the inverter braking power and braking resistor selection. Otherwise, inverter DC bus voltage phenomenon will affect the normal operation of the elevator in the brakina condition.
