One of the key electrical components in a car, a motor has been actively studied based on its reliability. In recent years, as the proportion of the motor has increased in a car, development of the motor with a high output and a low price has been required. IPMSM can cause a high torque per unit current by using a reluctance torque generated from the difference in the magnetic resistance, which is suitable for the motor which requires a high output. In particular, since the spoketype IPMSM with a concentrated flux structure can utilize non-rare earth metal-based ferrite magnets which are cheaper than rare earth metal-based permanent magnets such as neodymium, this can lower the motor price. In this paper, we study driving characteristics by analyzing the magnetic flux density and cogging torque that causes noise and vibration in accordance with the rotor shapes (Magnet, Rib) of the spoke-type IPMSM.
