Transient analysis of a line start hysteresis interior permanent magnet motor

A hysteresis interior permanent magnet (IPM) motor is a solid-rotor self-starting synchronous motor. Its rotor has a hysteresis ring made of 36% cobalt-steel alloys with buried Nd-B-Fe magnets inside it. This paper presents the transient analysis of a line start hysteresis IPM motor to investigate its starting and synchronization capability for different loading conditions. In this paper, d-q axis equivalent circuit models of a hysteresis IPM motor have been developed based on the elliptical approximation of the hysteresis loop. Simulations have been carried out to obtain the run-up responses of a 3-phase 4-pole 208V, 2.5kW line start hysteresis IPM motor. Simulation results are presented and analyzed in this paper. Experimental investigations are also carried out for a laboratory prototype 2.5 kW hysteresis IPM motor. There is a close agreement between simulation and experimental results. Both the simulation and experimental results exhibit that the proposed motor has good self-starting and synchronization capabilities.
