Abstract
The utility model discloses an improved stepping motor which comprises a rotor structure, a stator iron core, a front end cover and a rear end cover, wherein the front end cover and the rear end cover are respectively fixed at the front end and the rear end of the stator iron core through bolts. The rotor structure comprises a rotating shaft and a rotor, wherein a front bearing is arranged between the front end of the rotating shaft and the center of the front end cover, and a rear bearing is arranged between the rear end of the rotating shaft and the center of the rear end cover. The improved stepping motor is characterized in that the stator iron core comprises a plurality of stator stamped sheets which are arranged in vertically stacked mode, and each stator stamped sheet is provided with a plurality of coil installing grooves. Due to the fact that the stator iron core is formed by combination of the plurality of stator stamped sheets which are arranged in vertically stacked mode, when heat is generated in the stator iron core, the heat can be diffused outside through the stator stamped sheets, and therefore the heat dissipation effect is good. Moreover, machining technology of the stator stamped sheets is simple, and production cost is low.
Description
Technical field
The utility model relates to motor device, specifically, relates to a kind of improved stepping motor.
Background technology
In the prior art, stepping motor mainly comprises rotor structure, stator core, is bolted on front end housing and the rear end cap of stator core rear and front end; Rotor structure comprises rotating shaft and rotor, is provided with fore bearing between the front end of rotating shaft and the center of front end housing, is provided with rear bearing between the rear end of rotating shaft and the center of rear end cap.
Stepping motor be a kind of be the actuator of angular displacement with electroporation.Generally, when step actuator receives a pulse signal, it rotates a fixing angle with regard to the rotor structure of Driving Stepping Motor by the direction of setting.The user can come the pilot angle displacement by the control impuls number, thereby reaches the purpose of accurate location.Simultaneously, can also control by the control impuls frequency speed and the acceleration of electric machine rotation, thereby reach the purpose of speed governing.
Existing stepping motor, the housing that its inner stator core is as a whole is because rotor is when rotated, can produce certain heat, and this integrally-built stator case, radiating effect is bad, and whole stator case processing technology is complicated, and production cost is high.
Summary of the invention
The technical problems to be solved in the utility model is to overcome defects, and a kind of improved stepping motor is provided.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of improved stepping motor comprises rotor structure, stator core, is bolted on front end housing and the rear end cap of stator core rear and front end; Rotor structure comprises rotating shaft and rotor, be provided with fore bearing between the front end of rotating shaft and the center of front end housing, be provided with rear bearing between the rear end of rotating shaft and the center of rear end cap, it is characterized in that: described stator core comprises the stator punching that some stacked on top of one another arrange, and is provided with several coil mounting grooves on the every stator punching.
Say further:
Described each coil mounting groove is equipped with installing port.
Described every stator punching upper surface is provided with location notch, and the lower surface is provided with positioning boss, and the location notch of lower floor stator punching upper surface matches with the positioning boss of stator punching lower surface, upper strata.
Offer installing hole on the described stator punching.
Owing to adopted technique scheme, compared with prior art, stator core of the present utility model is combined by the stator punching of some stacked on top of one another settings, when producing heat in the stator core, heat can be dispersed into the outside by stator punching, good heat dissipation effect, and, the stator punching processing technology is simple, and production cost is low.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
