Embodiment Construction
[0012] Such as figure 1 , 2 , shown in 3, a kind of overcurrent fan-shaped piece that strengthens the cooling of the motor stator is composed of fan-shaped piece 1, several broken line flow channel steels 2, several long straight line flow channel steels 3 and several short straight line flow channel steels 4 Composition, broken line flow channel steel 2, long straight line flow channel steel 3 and short straight line flow channel steel 4 are all fixed on the fan-shaped piece 1 by laser spot welding; they are arranged in a full circle between the stator core segments The stator ventilation ditch is formed between them as a fluid passage, and the fluid flowing through the passage can cool the stator coil and the stator core.
[0013] The sector piece 1 is processed by silicon steel sheet with a thickness of 0.65 mm, and a whole number of sector pieces 1 are connected to form a ring.
[0014] Several uniformly distributed slots 5 are processed on the inner circle of the secto...
