Abstract
The utility model discloses an improved structure of a magnetic slot wedge of a stator component. The improved structure comprises a stator punching sheet, wherein the stator punching sheet is internally provided with a lower stator coil and an upper stator coil, the upper stator coil is provided with the magnetic slot wedge, a soft cushion strip is arranged in clearance between the magnetic slot wedge and the upper stator coil, and the soft cushion strip is in adhering connection with the upper stator coil and the magnetic slot wedge. According to the improved structure of the magnetic slot wedge of the stator component, disclosed by the utility model, the fabrication clearance between the magnetic slot wedge and the lower stator coil is effectively eliminated, the phenomenon of loosening and abrasion of the magnetic slot wedge after the long-time work in a stator punching sheet slot is avoided, the insulation performance is good, and the safety of an electric motor is high.
Description
Technical field
The utility model relates to a kind of electric machine, and the magnetic slot-seal that refers in particular to a kind of stator component improves structure.
Background technology
At present, the easy loose or dislocation of magnetic slot-seal that is in operation of motor on the market: at hard epoxy filler strip of slot wedge underneath, always there is the certain process gap in motor between magnetic slot-seal and core slots pad when rule.Under the effect of magnetic flux, the electromagnetic force that receives a double power frequency is drawn effect.Through the vibration of certain hour, the electrical steel sheet is with the wedge surface wearing and tearing of magnetic slot-seal, and magnetic slot-seal is just more loosening in groove like this, and wearing and tearing are just more serious, wipe mutually with rotor until exceeding stator rabbet, bring hidden danger for the safe operation of motor.Chinese patent publication number CN101867242A; Open day on October 20th, 2010; Name is called in " a kind of magnetic slot wedge structure " Chinese invention patent and discloses a kind of magnetic slot wedge structure, comprises heelpiece, middle pad, platinum resistance thermometer sensor, Pt1003, first adjusting pad, second adjusting pad and the magnetic slot-seal spare.Heelpiece places the slot wedge bottom, and first adjusting pad, second adjusting pad place the slot wedge oral area.This invention can reduce the no-load loss of motor, and the inhomogeneities of air gap flux density improves, and iron loss is descended significantly, simultaneously, also can reduce electric vibrating and noise.But the problem that the space is arranged between still unresolved magnetic slot-seal of this magnetic slot-seal and following stator coil.
The utility model content
The purpose of the utility model is to overcome the problem that the defective in technology space is arranged between magnetic slot-seal and the following stator coil of motor stator in the prior art, provides a kind of magnetic slot-seal of the stator component that has the space that can eliminate between magnetic slot-seal and following stator coil, improves motor safety property to improve structure.
The purpose of the utility model is to be achieved through following technical proposals:
A kind of magnetic slot-seal of stator component improves structure; Comprise stator punching; Be provided with in the stator punching composition groove and be provided with down stator coil and last stator coil; Last stator coil is provided with magnetic slot-seal, is provided with a cushion bar, cushion bar and last stator coil and magnetic slot-seal bonding connection between magnetic slot-seal and last stator coil in the space.Under the effect of magnetic flux, magnetic slot-seal will receive the electromagnetic force of a double power frequency and draw effect.Through the vibration of certain hour, the electrical steel sheet is with the wedge surface wearing and tearing of magnetic slot-seal.Be provided with that the electromagnetic force effect of drawing diminishes behind the cushion bar, and the cushion bar need not require great effort magnetic slot-seal just can to squeeze in the stator punching very much, the while can be avoided the damage of magnetic slot-seal, has made things convenient for the brush coating of magnetic slot-seal.
As a kind of preferred version, cushion bar and magnetic slot-seal contact-making surface are the plane, and cushion bar and last stator coil contact-making surface are arc-shaped concave.The purpose of arc-shaped concave is can perfectly fit to go up the outer surface of stator coil, and magnetic slot-seal is fixed in the stator punching groove.
As a kind of preferred version, cushion strip adoption thermal expansion material.The cushion bar is stained with lacquer through dipping lacquer the time, and oven dry back magnetic slot-seal is obtained effectively fixing by jam-packed.
As a kind of preferred version, the cushion bar is the wool packing ring.Wool comparatively softness and thermal expansivity effect is better.
As a kind of preferred version, the surface of magnetic slot-seal and end face are provided with the curing agent fixed bed.Under hot state, adopt manual brushing one deck E44 epoxy resin to add 650 polyamide curing agents, stopped the easy loose or dislocation of magnetic slot-seal on magnetic slot-seal surface and end face.
The beneficial effect of the utility model is:
1. effectively eliminated the technology space between magnetic slot-seal and following stator coil;
2. can produce the phenomenon of loosening wearing and tearing after having avoided magnetic slot-seal in the stator punching groove, to work long hours;
3. good insulating, motor safety property is high.
