Abstract

Axial field flux switching motor with sandwiched permanent magnet (AFFSSPM) is a novel of flux switching motor. Based on the vector control method, the mathematical model of the AFFSSPM is derived and the operating performance of the AFFSSPM in the overall operating region is investigated.
A novel control method for the AFFSSPM drive system, including the id =0, maximum torque per ampere, constant flux linkage, unity power factor control and flux-weakening strategy, is proposed.
A prototype of the 12/19 poles AFFSSPM motor is manufactured and tested. moreover, validity and feasibility of the proposed method were verified by experiments.
The AFFSSPM motor is one of the most efficient motors but control scheme of the 12S/19P AFFSSPM motor has not been specially reported to date. Thus, in this paper, we report on the operating performance of the AFFSSPM in the overall operating region is investigated.
Recently, suitable configuration and control strategy of the electric machines have been of the important research areas. Characteristics such as high-reliability, high-efficiency and better fault-tolerance capability are required for the EVs. Flux-switching permanent magnet (FSPM) motor attracts an increasingly attention because of its features over conventional rotor-PM motors.
]. Although AFFSPM motors offer higher torque density, the torque density is restricted owing to decreased available winding space because in addition to the armature windings, the PMs are placed in the stator. Hence flux switching machines with sandwiched permanent magnet were suggested .
