Method for determining motor parameters during commissioning of electric motor

A method for commissioning a synchronous or asynchronous electric motor having a stator and a rotor in which electrical power is applied to the motor when the rotor is stationary. The electric power is applied in two stages. The first stage utilizes a DC power that ramps in voltage over the duration of the first test to produce a current response that is employed to determine at least a first motor parameter. The second stage uses relatively high frequency AC power to generate one or more current responses that are employed to determine second and third motor parameters. A related electric motor drive system is also provided. 一种用于调试具有定子和转子的同步或异步电动马达的方法，其中当转子静止时将电功率施加到马达上。电功率分两个阶段施加。第一阶段利用在第一测试的持续时间上电压斜坡式变化的DC功率来产生用于确定至少第一马达参数的电流响应。第二阶段使用相对高频的AC功率来产生一个或多个电流响应，其被用来确定第二和第三马达参数。还提供了相关的电动马达驱动系统。
