Abstract
The present invention relates to the technical field of motor control, and discloses an apparatus for measuring excitation parameters of an induction motor and a method thereof. The method comprises: maintaining the induction motor static, and inputting a test current to a test phase of the induction motor; and calculating, based on a voltage of the test phase of the induction motor, a stator flux linkage of the test phase of the induction motor corresponding to a magnitude of the test current. The disclosure can conveniently and accurately measure excitation parameters of the induction motor.
