Recently, Inner Permanent Magnet (IPM) Synchronous Motors are known as a good candidate for hybrid electric vehicle traction drive application due to their unique merits like little volume, light weight, high efficiency and power factor and high reliability. However, behavior of this motors is quite depending on airgap length. This paper discusses the effect of airgap variation on d-q equivalent circuit model, also presents a novel structure of IPM synchronous motor for traction application with three layers of fragmental buried rotor magnets in order to achieve less torque ripple, iron losses and cogging torque, higher power factor and improving the electromagnetic torque per ampere and simulation of this motor. Thus, in order to extract the output values of motor and sensitivity analysis on hysteresis loop characteristics using 3D-Finite element model, then shows the back EMF, power factor, cogging torque, flux density, torque per ampere diagram of the IPM synchronous motor with variation of hard magnetic material hysteresis loop characteristics in rotor structure. This study can help designers in design approach of such motors.

W artykule przedstawiono zagadnienie wpływu wahań szerokości szczeliny powietrznej w maszynie synchronicznej z magnesami trwałymi (PMSM) na jej model matematyczny we współrzędnych d-q oraz nową strukturę PMSM z trzema częściowo zagrzebanymi warstwami magnesów wirnika na potrzeby trakcji. Proponowana budowa wpływa na redukcję m.in. wahań momentu maszyny, strat w żelazie, momentu zaczepowego, wzrost współczynnika mocy. Analizę przeprowadzono z wykorzystaniem metody elementów skończonych w 3-D.
