Detailed Description
The technical scheme of the utility model is further described with the attached drawings:
The utility model provides a chain belt iron core, includes iron core main part 1, tooth portion 2, the both sides limit of tooth portion 2 is equipped with chamfer 4, iron core main part 1 is formed by iron core towards 5 superposes layer upon layer, iron core towards 5 for chain belt heliciform structure, iron core towards 5 tooth portion 2 be equipped with through-hole 3, through-hole 3 is the rectangle structure, tooth portion 2's width is inequality, and from iron core towards the middle-upper segment of 5 to 5 towards the iron core towards the head end 501 of 5, tooth portion 2's width progressively increases gradually, from 5 middle-upper segment to terminal 502 towards the iron core, tooth portion 2's width is the same, and tooth portion 2's width difference has formed chamfer 4.
In this embodiment, the angle of the chamfer 4 is preferably an acute angle of 45 degrees.
Wherein chamfer 4 can guarantee when the coiling winding enameled wire, the structure of corner can not harm the enameled wire, can prevent that the department of bending lacquer film is easy to split.
In this embodiment, it is more preferable that the outer rings of the iron core sheets 5 stacked one on another are integrated by welding.
In this embodiment, more preferably, the size of the through holes 3 gradually increases from the head end 501 to the tail end 502 of the iron core stamped steel 5, and the through holes 3 are overlapped to form a through hole with a trapezoidal structure.
The material is saved and the tooth 2 structure is more stable than the through hole of the cube structure.
In this embodiment, more preferably, the iron core stamped steel 5 is made of a silicon steel sheet.
In this embodiment, more preferably, the thickness of the iron core stamped steel 5 is 0.5 mm.
in this embodiment, more preferably, the iron core stamped steel 5 is provided with a vent hole 6, and the vent hole 6 may be stacked layer upon layer to form an iron core vent channel.
The iron core is used as a part of a magnetic circuit of the motor and is used for placing a stator winding. In order to reduce eddy current and hysteresis loss caused by alternating magnetic potential in the iron core, the iron core material is formed by laminating silicon steel sheets with the thickness of 0.5mm, and insulating paint is coated on two surfaces of a punching sheet so as to reduce the iron core loss. In order to improve the cooling effect between the iron cores, radial ventilation channels are reserved along the axial direction.
In the winding process, the bending angle of the enameled wire at the tooth part is reduced, and the problem that a paint film at the bending part is easy to crack is effectively solved. And the chamfer angle is arranged, so that the using amount of the enameled wire can be saved. The single punching sheet is changed into the chain belt type punching sheet, the single punching sheet is overlapped according to the thickness of the iron core, and then the excircle is welded to form a whole. The multi-layer stacking can be used for manufacturing iron cores with different thicknesses according to different requirements. The process can improve the utilization rate of materials and reduce waste.
Finally, it should be noted that:
The skilled person can, with reference to the present disclosure, carry out the method and carry out its application, it being expressly noted that all similar substitutes and modifications apparent to the skilled person are deemed to be included within the present invention.
