摘要

A self-start interior permanent magnet (IPM) motor can be a potential replacement of the conventional induction motor because of its high torque density, smaller size, higher efficiency, and power factor. Traditional self-start IPM motors are equipped with cage windings in the rotor for providing the starting as well as the damping torque. Cage-quipped IPM motors have limited starting and synchronization capabilities. This paper introduces a novel self-start radial flux (RF) hysteresis IPM motor. The rotor of the hysteresis IPM motor has a cylindrical hysteresis ring made of semi-hard magnetic material. High energy density Nd-B-Fe magnets are buried inside the rotor hysteresis ring. The ring is supported by a laminated steel sleeve, allowing the flux to travel radially inside the hysteresis ring. In this paper, the design and performance analysis of a 3-phase 4-pole 1-HP RF-hysteresis IPM motor is carried out using finite-element analysis. The performance of the designed RF-hysteresis IPM motor is compared with similar 1-HP circumferential flux type hysteresis and cage-equipped IPM motors. Based on analysis and simulation, the RF-hysteresis IPM motor demonstrates higher starting and synchronization capabilities than conventional self-start IPM motors.
