Description

Technical field:

[0002] The invention belongs to the technical field of electrical machinery, and in particular relates to a flat wire motor coil twisting and forming mechanism. Background technology:

[0004] In the manufacturing process of flat wire motors, it is necessary to insert the formed hairpin coils into the grooves arranged along the circumferential direction of the stator, and then twist the two adjacent layers of the coils at the straight end relative to each other by a certain angle to meet the subsequent welding process of the motor; the stator has an even number of layers of coils, and is currently generally operated with simple tooling. Generally, two powers are used to twist the coils, one power drives the odd-numbered layers of coils to twist in one direction, and the other power drives the adjacent even-numbered layers of coils to twist in another direction. Due to the rebound of the coils, the coils are not neatly arranged radially at the end of the stator after twisting, resulting in poor twisting effect, affecting the subsequent processes and low efficiency.
