Example Embodiment

[0034] see in conjunction Figure 1 to Figure 10 As shown, the flat wire winding includes a flat wire unit 1 , and the flat wire unit 1 includes a flat wire hollow layer 2 .

[0035] After adopting the flat wire unit 1 including the flat wire hollow layer 2, a hollow flat wire winding can be formed, which can significantly reduce the skin effect generated when carrying a large current, save winding materials, and reduce winding costs. When bending flat wires, since the flat wire unit 1 is hollow, the bending resistance is reduced and it is easier to bend and form. The forming difficulty of the wire winding improves the forming efficiency of the flat wire winding.

[0036] Preferably, the flat wire hollow layer 2 extends along the length direction of the flat wire unit 1, and a larger length of the flat wire hollow layer 2 can be formed inside the flat wire unit 1, thereby reducing to a greater extent the noise generated when carrying a large current. skin effect. The flat w...

Abstract

The invention provides a flat wire winding, a motor stator, and a motor. The flat wire winding comprises a flat wire unit (1), and the flat wire unit (1) comprises a flat wire hollow layer (2). According to the invention, the flat wire winding can remarkably weaken the skin effect generated when a large current flows through the flat wire winding, and reduces the forming difficulty of the flat wire winding.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a flat wire winding, a motor stator and a motor. Background technique [0002] In recent years, the field of new energy vehicles has developed rapidly, and the competition in the industry is also increasing day by day. At the same time, the requirements for the power density of new energy vehicles are also getting higher and higher. From a technical point of view to improve the power density of the main drive system, some companies have proposed and developed flat wire technology solutions. [0003] With the advancement of technology, flat wire motors have been widely used and popularized, and their advantages such as high slot fill rate and low copper consumption have been fully utilized, but a series of problems such as skin effect and molding difficulties caused by this need to be solved urgently. Contents of the invention [0004] Therefore, the technical proble...
