Embodiment Construction

[0039] The specific embodiment of the present invention is described further below according to accompanying drawing:

[0040] This embodiment provides a flat-wire motor stator winding, including a wire-embedded stator. The appearance of the wire-embedded stator is as follows: Figure 5 shown. The embedded wire stator uses flat wire (square wire) for off-line; the stator core in the embedded wire stator contains 6 or more even-numbered flat wires in each stator slot, and the winding contains at least 2 (or a multiple of 2 above) ) branch winding.

[0041] The windings are evenly arranged in the iron core stator slots with a certain span, and two adjacent copper wires in each stator slot form a layer of windings. Taking a three-phase motor as an example, when q=2, each stator slot contains 8 flat wires as an example, and the normal span in each layer of wires includes the first wire of the first stator slot (that is, the first layer) Cross to the 2nd wire of the 7th stator s...

Abstract

The invention discloses a stator winding of a flat wire motor, and a wire-inserted stator comprises a stator core with 144 stator slots arranged at equal intervals, wherein each stator slot comprises 8 layers of flat wires; the three-phase winding structure comprises a U-phase winding structure, a V-phase winding structure and a W-phase winding structure, and each phase winding structure comprises two branch windings; in the U-phase winding structure, the power outgoing line of the first branch winding is connected with the power outgoing line of the second branch winding; in the V-phase winding structure, the power outgoing line of the first branch winding is connected with the power outgoing line of the second branch winding; in the W-phase winding structure, the power outgoing line of the first branch winding is connected with the power outgoing line of the second branch winding; in the three-phase winding structure, the star point connecting lines in the six branch windings are connected with one another. According to the invention, one conventional span and two cross-layer connection spans are included, the types of winding hairpins are reduced, and the manufacturing process difficulty of the coil inserting stator is reduced on the premise that the electromagnetic performance is ensured.

Description

technical field [0001] The invention relates to a stator winding of a flat wire motor, which can be applied to drive motors, generators or other non-vehicle motors in the field of oil-using vehicles and the field of new energy. Background technique [0002] In the design and manufacture of flat wire motors, various motor manufacturers and vehicle manufacturers in the industry have some different winding arrangements, which are different in terms of electromagnetic performance and process complexity. Different winding arrangements will affect the production of stators. has a direct impact on the level of complexity. [0003] There are many types of winding pins in the existing winding layout (the pins are used for continuous flat wires between the stator slots and the stator slots), and the manufacturing process of the embedded wire stator is very difficult. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a flat ...
