This paper deals with comparative investigation on permanent magnet synchronous machines (PMSMs) with identical stator structure based on electromagnetic field analysis. By considering their rotor types with rare-earth magnets, the influence of space vector pulse width modulation inverter on machine performance is investigated based on the predicted phase current. As analysis models, a surface-mounted PMSM (SPMSM) with parallel magnetization, a SPMSM with Halbach magnetization, and an interior PMSM (IPMSM) are employed for their comparison. For their effective investigation, machines are designed to have identical equivalent circuit parameters, such as resistance and induced voltage in no-load condition. Based on the dynamic modeling of the SVPWM inverter, the phase current is predicted, and their output characteristic, power losses and radial force density are comparatively investigated by electromagnetic field analysis. In addition, with a manufactured machine, the validity of this paper is demonstrated as well.
