Abstract
Recently, an interior permanent magnet synchronous motor (IPMSM) which has high power density and efficiency has been attracting attention for electric vehicle (EV) traction motor. Also motor design for smaller size and higher rotating speed is latest trend because it can make more space. But in high rotating speed, an induced voltage can exceed the DC link voltage. In that case, it can be difficult to control the motor and makes lower torque due to lack of voltage. In this paper, an improvement design for initial model of EV traction motor is conducted to reduce induced voltage value through shape change. In case of stator, various shape of chamfers are applied and in case of rotor, an eccentricity is applied. For each case, 2-D FEM is used for verification for value of an average torque at base rpm and a maximum induced voltage at maximum rpm. Finally, an improvement model is designed which has an induced voltage that does not exceed the DC link voltage.
