ABSTRACT:
A method and apparatus used with a motor controller for determining transient inductance and rotor resistance upon commissioning of the motor. The estimator drives a single phase of the motor with an excitation current at an operating frequency, determines the d-q axis stator synchronous feedback voltages, divides the excitation current by 2 to produce a positive current signal, multiplies the operating frequency by the positive current signal to produce a current frequency signal and then divides the q-axis voltage feedback by the current frequency signal to produce the transient inductance estimate, divides the d-axis voltage feedback signal by the positive current signal and subtracts stator resistance estimate therefrom to obtain a rotor resistance estimate.
