Abstract:
    This invention relates to a telescopiform dual-rotor generator and its shift and frequency conversion excitation system, in which, a permanent magnet internal rotor is matched on a sub-transmission shaft rotating relatively to a stator, a loop rotor rotating corresponding to the stator is matched on the primary shaft of the generator, a crab controller and a set collected control device are coupled in the mode of controlling wind direction under the main vane, and the main and sub-vanes are matched with main and sub variable adjusting units for adjusting oar pitch angles, and the adjusting units are coupled with the set collected control device in the mode of controlling the variable oar of the vane adjusting unit, a main and a sub vane rotation speed detection devices are set on the main and the sub-vanes transferring signals of rotation speed to the collected device of the set and the crab controller and the collected device are coupled in the mode of controlling wind rotationdirection under the main vane.
