Abstract
The utility model relates to a stepping motor, which comprises a stator, a rotor, a rotating shaft, a front bearing, a rear bearing, a front end cover, a rear end cover, and a stator inner protective layer, wherein the stator inner protective layer is arranged at the tooth part of a stator bore, and the stator inner protective layer is an epoxy glue coating layer. Compared with the prior art, the stepping motor has the advantages of preventing burr and burr flanging generated in stator honing, and the like.
Description
Technical field
The utility model relates to a kind of motor, especially relates to a kind of stepping motor.
Background technology
Composite stepper motor (Hybrid Stepping motor) is because the rotor air gap is smaller, so stator inner hole needs honing generally speaking.In the industrial mass manufacture process, consider production efficiency, the higher diamond dust honing cutter honing of roughness ratio is all adopted in the honing of stator inner hole.After traditional stepping motor stator honing, stator inner hole is easy to produce burr and flange.Burr and flange not only influence the stator facewidth, influence performance, and can be involved in the motor gas-gap, cause motor stuck.In addition, in the process of honing, also can produce lamella rubbish and burr between the silicon steel sheet, cause the distortion on the stator thickness direction.In postchannel process, because coiling waits axially loaded, this distortion can produce contraction, and shrinking the back air gap also can torsional deformation, causes occurring in the motor assembling process off-centre even stuck.Therefore, burr, flange and the influence thereof after the honing of elimination stator inner hole is the difficult problem of each company always.
The utility model content
The purpose of this utility model is exactly to provide a kind of stepping motor for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of stepping motor comprises stator, rotor, rotating shaft, fore bearing, rear bearing, front end housing, rear end cap, it is characterized in that, also comprises the stator interior protective layer, and this stator interior protective layer is located at stator inner hole tooth portion.
Described stator interior protective layer is the epoxy glue coating.
Compared with prior art, the utlity model has and produce burr and burr flange when preventing the stator honing, thereby stop of the influence of final motor assembling back burr motor noise and operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of stepping motor comprises stator 1, rotor 2, rotating shaft 3, fore bearing 4, rear bearing 5, front end housing 6, rear end cap 7, stator interior protective layer, and this stator interior protective layer is located at stator inner hole tooth portion.
Described stator interior protective layer is the epoxy glue coating.The stepping motor stator inner hole encases stator inner hole tooth portion by the epoxy glue coating, makes epoxy glue and combination unshakable in one's determination by oven dry then.Because the existence of glue when carrying out honing, can be with iron filings together, thereby the generation of having stopped burr.
Claims (2)
1. a stepping motor comprises stator, rotor, rotating shaft, fore bearing, rear bearing, front end housing, rear end cap, it is characterized in that, also comprises the stator interior protective layer, and this stator interior protective layer is located at stator inner hole tooth portion.
2. a kind of stepping motor according to claim 1 is characterized in that, described stator interior protective layer is the epoxy glue coating.
