Abstract

The traction motors used in electric vehicles (EVs) should satisfy trade-off requirements such as high torque at low speed, high efficiency at low torque regions, and a constant output in a wide speeds. To achieve this, several types of motors such as variable flux machines and variable parameter machines have been developed. Our research team focuses on a consequent-pole-type ferrite permanent magnet (PM) axial gap motor with field windings, in which the magnetic flux density can be varied. Although consequent-pole-type motors have previously been researched, no extant study has focused on the influence of the slot combination on the motor performance. This study investigates the magneto-motive force and rotor permeance of several motors.
