Electromagnetic Design of Concentrated Winding in a Direct-Drive Permanent Magnet Wind Generator with Evaporative-Cooling and Inner-Cooling System

Abstract:

This paper describes the fundamental principle of the direct-drive permanent magnet wind generator with evaporative-cooling and inner-cooling system and raises a method to apply concentrated winding to the electromagnetic design of this motor in order to simplify its processing technic. It also includes simulation and comparison of electromotive force of fundamental wave produced by concentrated winding under different slot-opening factors. A reasonable slot-opening factor was selected in the electromagnetic design of a 2 MW direct-drive permanent magnet wind generator with evaporative-cooling and inner-cooling system and the validity of the design has been proved by simulation.
