New Motor Having a Simple Structure with Three-Dimensional Magnetic Circuit and Loop Windings

Abstract

This paper presents a new motor with three three-dimensional magnetic cores and two loop windings driven by a normal three-phase inverter. This configuration reduces the number of parts, simplifies the production process, and downsizes the motor by a high copper slot fill factor and no end winding. This paper describes the working principle, the design approach, and the prototype evaluation results of the motor.
