홈페이지논문 초록 (Abstract)
In traction motors, efficiency characteristics are important, but vibration characteristics are also important. The vibration of the motor is caused by the magnetic flux generated by the current flowing through the stator winding and the magnetic flux on the rotor side. This is called armature reaction. The armature reaction not only generates torque, but also causes a pulsation called torque ripple. This paper aims to reduce the torque ripple of the Interior Permanent Magnet Synchronous Motor (IPMSM) used in the electric vehicle driving motor. Rotor asymmetric barrier and skew are applied to the asymmetric element applied to the model as a torque ripple reduction method. For comparison, the N-pole and S-pole asymmetric barrier models of the rotor are centered on the model without skew applied. Finite element method(FEM) based simulation tools are used to determine the degree of reduction.
