Abstract
The invention relates to a nested mouse-cage type direct-driving wind driven generator with a three-stator structure, which adopts a three-stator nested stator and rotor structure. A rotor has a three-bearing supporting structure comprising a front-end bearing, a middle bearing and a rear-end bearing and is reliable to operate. An outer stator is directly installed on the shell of a generator base; a middle stator is installed on a barrel-shaped support; an inner stator is installed on a dead axle by a spoke; a hub drives the rotor of the nested mouse-cage type direct-driving wind driven generator with the three-stator structure to rotate; and thus electric power is output by the three independent stators, i.e. the outer stator, the middle stator and the inner stator. The wind driven generator has the advantages of simple manufacturing and assembling process, high space utilization rate and high power density and is simple to install and convenient to maintain, the working requirement of the wind driven generator is satisfied, the rigidity of the rotor is improved, and the motor is reliable to operate.
