Abstract :
This paper presents a signal injection method without torque variation for the position sensorless control. Proposed method utilizes the maximum torque control frame that makes torque ripple caused by a signal injection minimized. It is proved from the definition of the maximum torque control frame and evaluated by experimental results.
