ABSTRACT:
A method for emulating induction motor operation using an electronically commutated motor (ECM) is described herein. The method includes receiving, at the ECM, a desired operating torque, accessing induction motor operating characteristics stored within the ECM, and calculating a new torque demand if a speed associated with the desired operating torque is greater than a breakdown speed of the induction motor. The method also includes setting an output torque for the motor substantially equal to the torque demand for the motor if the speed associated with the desired operating torque is less than the breakdown speed of the induction motor, moving the output torque toward the demanded torque if not substantially equal, and operating the motor at the output torque.
