Abstract
A method () of determining equivalent circuit parameters of a three phase induction motor is provided. The method () comprises applying () a current to a stator winding () of an induction motor (), and varying () a voltage applied to the stator winding to regulate the applied current to be a constant current. Application of the current is terminated () when the applied voltage has reached a constant voltage. The equivalent circuit parameters are determined () from the value of the constant current, the values of the applied voltage, and a time period until the applied voltage attains the constant voltage. The method may provide values for a resistance () of the stator winding, a resistance () of a rotor winding (), a magnetizing inductance (), and a total inductance leakage value () for the stator winding and the rotor winding.
