Abstract
The utility model discloses a kind of high-voltage motor stator core structure, comprise stator pressing ring, stator end plate, stator ventilation channel plate, stator punching, reinforcement.Stator pressing ring excircle evenly has the location groove of reinforcement and ventilation slot, and is processed with the screwed hole installing ventilating duct, be processed into the inclined-plane becoming 1 ° with vertical plane at trim ring near end face unshakable in one's determination.Whole stator core welding is more firm, reduces motor oscillating, reduces electromagnetic noise.Pad reduces, and is easy to welding, decreases welding job amount.Form symmetrical aeration structure, improve ventilation and radiating condition, reduce temperature rise.Structure is simple, reasonable in design, easy to implement, and successful, the stator core of various high-voltage motor can be widely used in.
Description
Technical field
The utility model relates to a kind of high-voltage motor stator core structure, belongs to technical field of motors.
Background technology
The structure of existing high-voltage three-phase asynchronous motor stator core, be respectively arranged with stator pressing ring at the some stator punchings laminated and stator ventilation channel plate two ends, stator pressing ring and stator punching are fixed by reinforcement, and publication number is the Chinese patent " stator core of high pressure bipolar machine " of CN201821240U is exactly this structure.In this structure, without aeration structure on trim ring, stator core ventilation and heat is not good; Without installing the location structure of reinforcement on trim ring, reinforcement is directly welded on the side of trim ring, and it is many to locate difficult solder joint, and welding job amount is large; The trim ring end face contacted with punching is plane, and press stator core operation technological requirement is high.And on ventilating duct or field ring gusset, need hole of bursting at the seams, increase manufacturing procedure and workload.
Summary of the invention
The technical problems to be solved in the utility model is, stator pressing ring is without ventilation and reinforcement location structure and to compress operation requirements unshakable in one's determination high, and welding job amount greatly and need out through wires hole on ventilating duct or field ring gusset.
In order to solve the problems of the technologies described above, the technical solution of the utility model there is provided a kind of high-voltage motor stator core structure, comprise the some stator punchings and stator ventilation channel plate that laminate, stator end plate is located at the outer end of stator punching, the two ends of the stator punching after laminating and stator ventilation channel plate are respectively arranged with stator pressing ring, stator pressing ring and stator punching are fixed by reinforcement, it is characterized in that, be processed into the conical surface with the trim ring end face of end plate contact, this conical surface and vertical plane become to be greater than the angle α that 0 ° is less than or equal to 1 °.
Preferably, as the ventilation slot of the through wires hole of cable and several groove while that described stator pressing ring excircle having several, ventilation slot and groove stagger uniform; Ventilation slot forms symmetrical aeration structure; Recess width is equal with described reinforcement width, and reinforcement is positioned in the groove of two ends stator pressing ring, makes described stator punching, described stator pressing ring, described reinforcement become to be integrated by welding.
The high-voltage motor stator core structure that the utility model provides, whole compacting unshakable in one's determination is tightr, and welding is more firm, ventilation and heat more reasonable structure, serves the effect reducing motor oscillating, reduce electromagnetic noise, reduce temperature rise, reduce workload very well.
