Abstract:This paper presents a novel auxiliary slot interior permanent-magnet (IPM) motor. It not only plays the role of magnetic isolation and reduces the eddy-current (EC) loss, but also facilitates the ventilation and heat dissipation of the rotor. Initially, using a high-speed 6-slot and 4-pole IPM motor as an example, the structure characteristics of the auxiliary slot permanent-magnet (PM) motor with magnetic isolation and heat dissipation are explained. Subsequently, the finite-element method (FEM) is employed t… Show more
