Abstract :
In this paper, the flux-memorization concept is extended to switched-flux (SF) machines featuring high torque density and rotor robustness. Two emerged hybrid permanent magnet (HPM) SF memory machines (SFMM) having full-pole-wound (FPW) and half-pole-wound (APW) configurations are proposed, which embrace such merits as high torque capability and efficient flux adjustment without excitation loss. The topologies and operating principles of the machines are described. Their electromagnetic characteristics with emphases on back-EMF, cogging/steady torque, and efficiency are analyzed and compared by finite element method (FEM). Experimental verification is implemented on a FPW prototype.
