Double Stator Axial-Flux Switched Reluctance Motor for Electric City Commuters

Reluctance Motors which is constructed without rare-earth magnet and robust structure is one of the most suitable in-wheel motors for electric vehicles. In addition, an axial-flux structure has possibility of effective utilization of in-wheel flat motor space and a double stator structure is good at the exhaust heat. This paper presents the designed process of a DSAFSRMs (Double Stator Axial Flux SRMs) and their performance through simulations and experiments. The Manufactured prototype DSAFSRMs have superior torque characteristics depend on rotational speed to a same size geared permanent magnet motor. Finally, a small city commuter vehicle equipped with the prototype DSAFSRMs for in-wheel direct drive and its road test is done successfully.
