Problems solved by technology

[0002] In the existing permanent magnet wind power generator, the wind blade is installed on the cantilever shaft protruding from the front end of the motor. Due to the large diameter of the wind blade of the wind power generator, the force is uneven, and the acceleration and deceleration are frequent. Therefore, the wind power generator with this structure It is very easy to cause the overall vibration of the motor
In order to reduce the overall vibration of the wind power generator, the overall structure of the motor is required to be rigid. Therefore, the technical solution adopted in the prior art is to further increase the weight and volume of the motor, making the already heavy and large wind power motor even more cumbersome

Embodiment Construction

[0014] The present invention is described in detail below in conjunction with accompanying drawing:

[0015] The vibration damping device of the permanent magnet wind power generator includes a disk 2 which is arranged inside the motor stator casing 1 to limit the longitudinal movement of the rotor. Vibration-absorbing structure of magnetic wind turbine components 4.

[0016] The damping structure 4 includes an elastic element 41 arranged on the inner wall of the disc 2 and an elastic member 42 arranged on the inner wall of the housing end cover 3, and a steel ball is arranged between the superelastic element 41 and the elastic member 42 43. The elastic element 41 can isolate the steel ball 43 and play a role of buffering. The elastic element 42 has good adhesion performance and can be pasted on the inner wall of the stator shell.

[0017] The elastic element 41 is provided with a semicircular groove 411 , and the steel ball 43 is placed in the semicircular groove 411 .

【Technical field】 [0001] The invention relates to a damping device for a permanent magnet wind power generator. 【Background technique】 [0002] In the existing permanent magnet wind power generator, the wind blade is installed on the cantilever shaft protruding from the front end of the motor. Due to the large diameter of the wind blade of the wind power generator, the force is uneven, and the acceleration and deceleration are frequent. Therefore, the wind power generator with this structure It is very easy to cause the overall vibration of the motor. In order to reduce the overall vibration of the wind power generator, the overall structure of the motor is required to be rigid. Therefore, the technical solution adopted in the prior art is to further increase the weight and volume of the motor, making the already heavy and large wind power motor even more cumbersome . [0003] The present invention is made based on such circumstances. 【Content of invention】 [0004] The...
