Sensor-less Vector Control of a Novel Axial Field Flux-Switching Permanent-Magnet Motor with High-Performance Current Controller

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. Validity and feasibility of the proposed method were verified by experiments.
