Abstract :
In this paper, a new multiphase polygonal-winding permanent-magnet brushless dc (PMBDC) machine is proposed and analyzed. The originality of the proposed machine lies on the multiphase polygonal-winding stator and the surface-inset permanent-magnet rotor. Because of its unique structure and operating principle, a circuit-field-torque coupled time stepping finite-element method is also employed for analysis. The designed machine is prototyped and the analysis is verified by experimentation.
