Problems solved by technology

Due to the existence of insulating paint varnish, the construction of the anti-corrosion layer has brought troubles of cleaning after baking and re-spraying the middle paint and top coat, and also caused a waste of insulating paint
The process of grinding the remaining insulating varnish varnish and paint film will also cause relatively large dust pollution to the environment

Abstract

The embodiments of the invention provide a manufacturing method of a stator. The method comprises the following steps that: a stator bracket body is manufactured, and the surface of the stator bracketbody is sequentially coated with an anti-corrosion layer and a protective layer, so that a stator bracket can be formed; a stator core and a stator winding are manufactured, the stator bracket, the stator core and the stator winding are assembled, dipped, and baked, and therefore, a stator is obtained. In addition, the embodiments of the present invention also disclose a stator, a generator, anda wind driven generator set. According to the manufacturing method of the stator, a procedure for polishing and cleaning and a procedure for complementary intermediate coat and finishing coat sprayingafter the baking of the stator are omitted, and therefore, dust pollution and organic gas volatilization pollution to the environment can be decreased.

Description

Technical field [0001] The invention relates to the technical field of wind power generation, in particular to a stator and a manufacturing method thereof, a generator and a wind power generating set. Background technique [0002] With the development of wind power technology in China, the capacity of wind turbines has developed from kilowatts to megawatts, and the windings of the stator, the heart of the generator, have also evolved from the scattered windings of small-capacity generators to large-capacity generators. Formed windings have made significant progress. Therefore, when manufacturing large-capacity wind power generators, higher requirements are put forward on the manufacturing process of the stator. [0003] However, the applicant found that the existing stator frame has been sprayed with two layers of primer and medium paint among the three anticorrosive coatings on the surface before dipping. After baking, the insulating paint film and paint bumps formed on the surfa...
