Characteristic analysis of high-speed Interior Permanent Magnet Synchronous Motor

This paper present characteristic analysis of high-speed Interior Permanent Magnet Synchronous Motor (IPMSM). Single-layer buried permanent magnet type and multi-layer type are modeled and investigated. Finite element analysis method is used to obtain the magnetic flux distributions of IPMSM. Parameters of IPMSM such as d-q axis inductances and torque curve are calculated and compared.
