Abstract
The axial gap structure of a half-wave rectified variable field flux motor (AG-HVFM) has been proposed, which has a double stator structure and field winding short-circuited by a diode. Although the AG-HVFM can achieve a high-efficiency drive in wide speed and torque range via variable field flux control, its structure deteriorates the average torque and torque ripple. In this paper, we sequentially design the core shape, aspect ratio, and current control method for an AG-HVFM to improve its torque characteristics.
