Rotor Construction of Double-Fed Induction Generator

摘要

The present invention relates to a double-excitation induction generator, in particular, the load-side bearing is formed between one end of the generator case and the load side of the rotary shaft, and the half-loaded bearing is formed between the outside of the slip ring case and the end of the rotary shaft, Easy access to the bearings makes it easy to repair the bearings in high and narrow spaces of wind power plants and tidal current facilities, and to prevent the separation of carbon brush powder (fine dust) for effective space separation between the generator case and slip ring case. The present invention relates to a dual excitation induction generator that can integrally form a slip ring fan for air flow inside a slip ring case to simplify the structure of the overall product. ; Double excitation induction generator, load-side bearing, half-load bearing, slip ring fan, blocking fan,
