摘要：
A lightweight wheel structure developed for rotor and stator use in large diameter direct-drive wind turbine generator is presented. The wheel structure uses layered sheet-steel elements to form the spokes and rim. This novel wheel structure is assumed to be more flexible than the existing conventional machine designs. Concerns with the dynamic response of the structure form the key motivation of the study presented here. As such, a computationally efficient methodology to predict the dynamic response has been presented. The dynamic model is employed to simulate the transient effects at startup and effects of cogging excitation on the direct-driven wind turbine.
