Motors for automotive chassis components require compact size due to space constraints. Therefore, a rare earth permanent magnet

synchronous motor (PMSM) is mainly used as the motor applied to the chassis system. The magnetic concentrated flux-type PMSM with

the ferrite magnet is likely to be used as a motor for the chassis system because it can increase the air magnetic flux density as the rare

earth PMSM. The most important thing for the design of concentrated flux-type motor is to reduce the flux leakage. In order to reduce

the leakage flux, it is necessary to increase the reluctance of main leakage path in the rotor core. Increase in magnetic reluctance of flux

path is necessary to reduce the flux leakage. Accordingly, a new rotor structure with a 3-dimensional (3D) magnetic circuit that can

reduce leakage flux is proposed in this paper. In order to easily analyze three - dimensional complex magnetic circuits, an equivalent 2D-

3D model was applied to analyze the characteristics.
