Abstract
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.
