Lamination device and lamination method for stator core of direct drive permanent magnet generator

Abstract

The invention discloses a laminating device and method of a direct-drive permanent magnet generator stator core. The laminating device comprises a stator laminating upper cover plate, a stator laminating lower bottom plate, a stator laminating die core, a stator laminating upper pressing plate and a stator laminating fixing plate. The laminating method includes the steps that a silicon steel sheet with the surface provided with a self-adhesive hot-pressed insulating coating is selected as a stator core raw material; after being assembled through the laminating device, the silicon steel sheet is heated to 200 DEG C and kept at the temperature for one hour, and then the stator core with good insulating performance can be obtained. By means of the laminating device and method, the laminating of stator core laminas, the laminating coefficient of the stator core and the appearance quality of the product are guaranteed.

Description

technical field [0001] The invention relates to a lamination device and a lamination method for a stator core of a direct-drive permanent magnet generator and belongs to the field of motor generator manufacturing. Background technique [0002] The lamination of the traditional motor stator core is generally guaranteed by self-riveting and welding. During manual welding, the welding speed and the emotions of the personnel are unstable, so it is difficult to achieve uniform quality, and each stator It is difficult to ensure that each sheet is overlapped and stacked to ensure the flatness of the punched sheets. The stator core is prone to conduction of the punched sheets through welding and lamination, and the surface of the welded iron core is polished with a grinder. , the appearance quality is still not good, and the insulation function on the outside of the iron core fails, which cannot meet the requirements of foreign high-end customers.
