Abstract
In this article, two flux-switching permanent magnet (FSPM) motors with pole-changing design (PC-FSPM) and hybrid-excitation design (HE-FS) are compared. First, the evolution processes of these two motors from a conventional FSPM motor are introduced based on the pole-changing (PC) and hybrid excited (HE) designs. Then, the operation principles of the two motors are introduced based on air-gap field modulation theory. Next, the two motors are optimized and compared by finite-element analysis (FEA). The result shows that the speed-regulation ability from the PC operation is better than its counterpart in addition to the torque advantage. A prototype of the PC-FSPM motor is manufactured and tested. The measured results agree well with FEA ones.
