Abstract

This study describes a Variable Leakage Flux type Interior Permanent Magnet synchronous motor (VLF-IPM) for an automobile traction motor. The proposed VLF-IPM can control the leakage flux in the rotor core depending on the armature reaction. As the motor can suppress d-axis current to reduce the back-EMF, the motor improves not only the motor efficiency but also the inverter efficiency in the high speed area. It is experimentally confirmed that the VLF-IPM can achieve the high efficiency driving in the wide speed range.
