Document Type and Number:
WIPO Patent Application WO/2021/027428
Kind Code:
A1
Abstract:
Provided are an electromagnetic assembly of a brake, a brake, and an electric motor, relating to the technical filed of braking. The electromagnetic assembly comprises a frame and a coil, wherein the frame is provided with a first flange and a second flange, and a coil winding groove is provided between the first flange and the second flange; the coil is wound around the coil winding groove to form a winding, and the winding is provided with two wire outlet ends; each of the wire outlet ends is connected to a lead wire, and a connection position between the wire outlet end and the lead wire protrudes out of a radial outer contour of the frame; a magnet yoke comprises an inner ring and an outer ring that are coaxially arranged, and a mounting groove for placing the winding is formed between the inner ring and the outer ring; a lead groove is provided in the outer ring, the connection position between the wire outlet end and the lead wire is located in the lead groove, and the lead wire is led out by means of the lead groove. According to the present application, when winding is carried out, the lead wire can be placed in the lead groove; therefore, the lead wire cannot occupy too much space of the frame on a winding assembly, thereby improving the groove filling rate, and the power density of a brake.
