Abstract
The utility model relates to a motor stator, belongs to the field of mechanical devices, and is used for motor manufacture. The stator consists of stator punching pieces, stator pressing pieces, stator buckle pieces and winding coils. The stator pressing pieces are arranged at two ends, the stator punching pieces which are stacked orderly are clamped between the stator pressing pieces, arc-shaped chamfers are arranged on inner edges of coil inserting punched holes on the stator pressing pieces close to outer end faces, the stator buckle pieces buckle the stator pressing pieces and the stator punching pieces together, and the winding coils are embedded in coil inserting slots 4, thereby forming the motor stator.
Description
Technical field: a kind of motor stator, belongs to mechanical device field, for motor manufacture.
Background technology: in the manufacture process of motor stator, traditional method is to use to withhold sheet and withhold together stacking neat stator punching (silicon steel sheet), make stator core, then in stator core, embed the coil that coiling is good, make a complete stator.
But can produce in the course of processing, some we do not wish situation about occurring yet, as thinner in stator punching, and the stator punching above when withholding can deform, and in the gap after distortion, when dipping lacquer, can infilter more paint, causes air spots.In addition, because stator punching is very thin, after being shaped, edge, rule hole is right angle, easy scratch winding wire lacquer painting during rule, and the insulation that reduces wire causes line turn-to-turn fault.
Summary of the invention: in motor is produced, the quality of motor stator plays very large effect to the quality of whole motor.Because stator punching is thinner, when withholding, can deform, particularly the larger motor stator of diameter can infilter more paint in the gap after distortion when dipping lacquer, causes air spots.For improving the quality of stator, overcome the defects such as stator punching distortion, scratch coil lacquer painting, the utility model will provide a kind of motor stator of new structure.
A kind of motor stator, is comprised of stator punching, stator compressing tablet, stator cramp and winding coil.Stator compressing tablet 2 is placed in stator two, stacking neat stator punching 1, is clipped in the middle, and together with stator cramp 3 is withheld after stator compressing tablet 2 is compressed with stator punching 1, winding coil is embedded in line embedding groove 4, forms a complete motor stator.
Stator punching is silicon steel sheet, is provided with more than 12 line embedding grooves in punching, along circle-shaped, is uniformly distributed, and stator cramp is flat strip steel bar.
By thickness, the steel plate more than 1.5mm processes stator compressing tablet, has and the corresponding line embedding groove of stator punching on stator compressing tablet, and edge is provided with cramp bayonet socket, on the outer end face of stator compressing tablet, at the inward flange of line embedding groove, is provided with circular-arc smooth chamfering.
Because the steel plate rigidity of compressing tablet is better, not yielding, make whole stator surface smooth; Because the line embedding groove edge at end face is provided with chamfering, smooth transition can prevent that coat of paint is by scratch when embedding coil, has not only improved effect, and has guaranteed quality.
Accompanying drawing explanation: Fig. 1 is motor stator structure schematic diagram, and Fig. 2 is stator compressing tablet schematic diagram, and Fig. 3 is A-A cutaway view,---stator punching, 2---stator compressing tablet, 3---stator cramp, 4---line embedding groove, 5---cramp bayonet socket, 6---chamfering in figure: 1.
Embodiment: a kind of motor stator, is comprised of stator punching, stator compressing tablet, stator cramp and winding coil.Stator compressing tablet is placed in stator two, stacking neat stator punching, is clipped in the middle, and stator cramp is withheld stator compressing tablet with stator punching together with, winding coil is embedded in line embedding groove 4, forms motor stator.
Stator punching is silicon steel sheet, is provided with 18 line embedding grooves in punching, along circle-shaped, is uniformly distributed, and stator cramp is flat strip steel bar.
By thickness, the steel plate more than 1.5mm processes stator compressing tablet, has the line embedding groove consistent with stator punching flat shape on stator compressing tablet, and edge is provided with cramp bayonet socket, on the outer end face of stator compressing tablet, at the inward flange of line embedding groove, is provided with circular-arc chamfering.
