Abstract

The invention provides stator iron core winding units, a stator assembly of a disc type motor and the disc type motor. The stator iron core winding units all comprise stator iron cores which are in ridge arc transition and are in a triangular prism shape, integrated windings and fixing glue, the integrated windings comprise multiple-layer wire winding coils spirally wound on the outer side faces of the stator iron cores in the length direction of the stator iron cores, the multiple-layer wire winding coils are bendingly wound by flat wires in the length direction of the cross section of the flat wires, and the radius of ridge transition arcs of the stator iron cores is not smaller than the length of the cross section of the flat wires. The bending portions of the flat wires can be prevented from fracturing.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator core winding unit, a stator assembly of a disc motor and a disc motor. Background technique [0002] A disc motor in the prior art generally includes a fixed disc and a stator core winding unit, and the stator core winding unit includes a stator core and a winding wound on the stator core. In the prior art, most of the windings are coiled by enameled wires, and in order to obtain sufficient power, it is better to use flat wires to wind the windings. During the winding process of the flat wire, if the bending angle is large, a large stress will be generated, and the flat wire is easy to crack after a period of use. Contents of the invention [0003] The main purpose of the present invention is to provide a stator core winding unit, a stator assembly of a disc motor and a disc motor, aiming at preventing cracks at the bends of flat wires. [0004] In order to achieve th...
