Abstract

This paper deals with characteristics of Interior Permanent Magnet Synchronous Generator (IPMSG), which has been developed for offshore wind turbine with variable operation condition [1,2]. The performance analysis such as characteristics of loss and efficiency, torque ripple, backEMF, demagnetization of PMs and etc. and design of IPMSG with slitting and skewing which reduce the THD are implemented based on 3d non-linear FEA [3]. In particular, this paper presents the design of 5.6MW IPMSG by taking account of mechanical stress analysis.
