Example Embodiment
[0016] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0017] As shown in the embodiment shown in the figure, the stator punch is circular and consists of a ring-shaped yoke 1 and 27 wire-inserting slots 2 evenly distributed on the ring-shaped yoke. Closed notch.
[0018] The outer circle diameter of the stator punching piece is 90-110mm, and the inner circle is the inner diameter of the ring-shaped yoke 60-75mm.
[0019] In the embodiment shown in the figure, the outer circle diameter of the stator punch is d=104.8mm, and the inner circle is the inner edge diameter P=72mm of the annular yoke 1.
[0020] The slot height of the stator punching slot 2 is 12-15mm, and the slot top is flat.
[0021] In the embodiment shown in the figure, the slot height of the stator punching piece is h=12.8mm, the slot top is flat, and both ends are chamfered.
[0022] Using the laminated stator core composed of the stator pu...
