Abstract

The invention provides a ferromagnetic lamination sheet, a magnetic conductive part of a motor, the motor with the magnetic conductive part, a motor winding structure with the magnetic conductive part, a motor with the motor winding structure, a wind generating set, a wind power plant, electric energy and magnetic field energy transformation equipment, and a blade for the wind generating set The magnetic conductive part comprises a winding groove, and the inner wall of the winding groove is provided with a plurality of holes. According to the invention, the magnetic conductive part can effectively keep and fix a liquid insulating medium through the hole structure when the magnetic conductive part is used for insulating processing, and forms a rooted central elastic base at a ferromagnetic boundary after the solidification of the liquid insulating medium, and effectively prevents the insulating medium from being peeled, broken or separated.

Problems solved by technology

[0012] In addition, in the prior art, when the slot wedge 300 is used to fix the coil 200 in the slot, since the ferromagnetic laminations are made of completely different materials from the traditional slot wedges, the elastic modulus differs greatly. The interface of the adhesive layer formed by the insulating medium between the notch tooth pieces will appear "debonding", resulting in a gap between the slot wedge and the core notch silicon chip, and moisture and water will naturally enter the slot along the debonding gap to destroy the insulation

Even if the slot wedge is made of magnetically conductive material, it cannot ensure that the bonding layer interface between the slot wedge and the core notch teeth is firm, and cannot prevent moisture and water from naturally entering the winding slot along the fracture gap of the bonding layer to damage the insulation.

[0013] Therefore, the motor winding of the traditional structure can no longer effectively guarantee the insulation performance and service life of the stator winding
