Abstract
The starting torque of a single-phase permanent magnet brushless de motor i s investigated, for both radial and parallel magnetization. Finite element analysis is used to assess the relative merits of alternative methods of in troducing the required airgap asymmetry, viz. tapered airgap, stepped airga p, asymmetric airgap, and slotted teeth. The predicted results are validate d experimentally.
