Description

Technical Field

[0001] The present invention relates to the technical field of stator flat wire production, in particular to a 2D forming device for stator flat wire. Background Art

[0002] Taking the motors used in new energy vehicles as an example, stators using flat wire windings have a high copper fill factor, which improves the motor's power density. Currently, stators with flat wire windings have become a trend in the new energy vehicle sector and offer significant advantages. For example, the slot fill factor of flat wire windings can reach over 70%, improving motor efficiency. Furthermore, the flat wire conductors arranged in the stator slots have a small inter-turn contact area, reducing the probability of inter-turn or inter-phase insulation failure, significantly extending the motor's operating voltage range. Furthermore, flat wire conductors can directly transfer heat to the iron core or other cooling medium, providing strong heat dissipation capabilities.
