Permanent-Magnet Machines for Distributed Power Generation: A Review

A review of permanent-magnet machines for distributed power generation is presented. Radial-flux, linear and axial-flux machine configurations are discussed with reference to generation that utilize energy resources such as wind, wave energy, and natural gas. Isolated operation and grid-connected operation are considered. Some of the authors' research work on a surface-inset permanent-magnet synchronous generator (PMSG) for autonomous power system application is also included.
