Description

Technical Field

[0001] The utility model relates to the technical field of flat wire motors, in particular to a flat wire motor winding positioning device. Background Art

[0002] In the actual application of new energy vehicles, as the indicators of high power density and high torque density are getting higher and higher, flat wire with higher slot fill rate has become the first choice in motor design. The main winding forms of flat wire motors are Hair-pin, I-pin, W-Pin, etc. Among them, Hair-pin is shaped like a hairpin. It is first formed, then inserted, and finally welded on one side; I-pin winding is shaped like the letter "I", directly inserted, and then welded on both sides. This method does not require single-slot assembly, which helps to reduce the reserved space for winding assembly. However, the welding process is relatively cumbersome, and the end size is large; W-Pin winding is mainly optimized at the welding end to improve the performance and efficiency of the motor, so W-Pin winding form is more commonly used.
