Structural design and mechanical performance analysis of dual-stator brushless doubly-fed generator

Brushless doubly-fed generator (BDFG) has a good application prospect on the wind power generation field. In order to improve the power density, a new type of dual-stator brushless doubly-fed generator (BDFG) with magnetic-barrier rotor is presented in this paper. The overall structure design method and mechanical performance of DSBDFG is put forward and analyzed. In this paper, the stress analysis is carried out on the magnetic ring, the stationary shaft, end cover and chassis, and is determined its reasonable size and thickness, in order to achieve the purpose of stress analysis of this motor.
