摘要

This article presents a novel 6/8-pole changing line-start permanent-magnet synchronous motor (LSPMSM) for improving the starting and synchronization capabilities. A 6/8-pole changing stator winding with simple structure, convenient switching, and speed detection capability is designed and studied. The synchronization process, which follows the 6/8-pole winding switching process, is analyzed. The effects of the switching speed, switching phase difference, and the rotor resistance on the synchronization process, respectively, are studied. Moreover, on the basis of the improvement of the starting capability utilizing the pole changing starting strategy, the rotor resistance is appropriately designed smaller to simultaneously balance the synchronization capability. The larger maximum moment of inertia that the motor can pull into synchronization validates the analysis. Through processing, both starting and synchronization capabilities have been improved for the proposed 6/8-pole changing LSPMSM compared with the conventional 8-pole LSPMSM.
