- Abstract
- A study on the iron-loss reduction of 110kW-class Interior Permanent Magnet Synchronous Motor (IPMSM) for Light Railway Transit (LRT) is conducted in this paper. In general, the iron loss of IPMSM is a value that depends on the characteristics of core material and non-oriented electrical steel is used as core material of IPMSM. In order to reduce the iron-loss of IPMSM, both non-oriented electrical steel and grain oriented electrical steel are applied as core material in this study. The iron-loss of 110kW-class IPMSM can be reduced approximately 40% comparing to the existing IPMSM by applying grain oriented electrical steel to the stator teeth.
