TORQUE CHARACTERISTIC OF DOUBLE-STATOR HYBRID DIRECT DRIVE MOTOR WITH SERIES MAGNETIC CIRCUIT

In this paper, a novel double-stator hybrid direct drive motor scheme is presented with series magnetic circuit. Based on the analysis of the magnetic circuit of the motor, magnetic network model of three-phase DD motor with series magnetic circuit is set up. And through linear analyzing, the torque characteristic is obtained. Experiments for the prototype indicate that using the structure of double-stator and three-phase series magnetic circuit, the hybrid variable reluctance motor has higher ratio of torque to volume. Further more through optimizing design the electromagnetism parameter and structure parameter, the motor can obtain higher output torque, lower moment of inertia and faster system response characteristic.
