Insulation racks (20) made of insulating materials are arranged on the axial end surfaces of the stator core (10), through holes (21) matched with the trunkings (11) of the stator core (10) are formed on the insulation racks (20). The squirrel-cage motor stator reduces the transmission of the leakage current between the coils exposed out of the axial end surfaces of the stator core (10) and the stator core (10).
Description
Technical field
The utility model relates to a kind of squirrel cage motor, particularly a kind of mouse cage type motor stator.
Background technology
Squirrel cage motor comprises stator and rotor.Stator comprises the stator core that has a plurality of wire casings, and stator core is that silicon steel material is made, and is wound with the enamelled wire coil that multiturn is made of metallic copper in its wire casing.Behind the electrical power, when the insulating varnish of coil comes off, when perhaps the insulating varnish on stator core surface came off, coil and wire casing in the stator core can produce leakage current, and then interior coil and the stator core of wire casing will produce current delivery, thereby influences motor properties.In order to prevent that leakage current and stator core from producing the leakage current transmission, coil generally is installed in the wire casing of stator core by insulating paper, reducing the leakage current between coil and the stator core, thereby reduces the leakage current transmission that produces between coil and the stator.Therefore, adopt insulating paper that the wire casing of coil and stator core is isolated, make coil and stator core keep insulation.But expose the leakage current that between the coil of stator core axial end and stator core, produces and do not have the corresponding protection measure.
The utility model content
Technical problem to be solved in the utility model is, overcomes above deficiency, and a kind of mouse cage type motor stator that leakage current transmits between the coil of stator core axial end and stator core that can reduce to expose is provided.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of mouse cage type motor stator, comprise the stator core that has a plurality of wire casings, the axial end of described stator core is provided with the insulating frame made from insulating material, and described insulating frame is provided with the through hole that the wire casing with stator core matches.
Further, the excircle of described insulating frame is provided with round edge.
Further, be evenly distributed with a plurality of wirings hole on the described round edge.
Further, the axial end of described stator core is provided with a plurality of installing holes, and described insulating frame is provided with the erection column that matches with described installing hole.
The beneficial effects of the utility model are: the utility model mouse cage type motor stator, be provided with the insulating frame made from insulating material at the axial end of stator core, and insulating frame is provided with the through hole that the wire casing with stator core matches.In the wire casing of stator core during winding around, earlier insulating frame is fixed on the stator core, then coil is wrapped in the wire casing of stator core and in the through hole of insulating frame, at this moment, expose the leakage current that between the coil of stator core axial end and stator core, produces, will be insulated frame and isolate, just can not produce the leakage current transmission between coil and the stator core.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As Figure 1-3, the utility model mouse cage type motor stator, comprise the stator core 10 that has a plurality of wire casings 11, the axial end of described stator core 10 is provided with the insulating frame made from insulating material 20, and described insulating frame 20 is provided with the through hole 21 that the wire casing 11 with stator core 10 matches.
The excircle of described insulating frame 20 is provided with round edge 22.Round edge 22 can shelter from the coil of insulating frame 20 axial ends, avoids coil to be collided the back and damages.
Be evenly distributed with a plurality of wirings hole 23 on the described round edge 22.The effect in wiring hole 23 is that the convenient multiturn coil that insulating frame through hole 21 is stretched out bundles.Can use cotton rope or band that multiturn coil is bundled.
The axial end of described stator core 10 is provided with a plurality of installing holes 12, and described installing hole 12 is positioned at the outside of wire casing 11, and described insulating frame 20 is provided with the erection column 24 that matches with described installing hole 12.Installing hole 12 on the stator core 10 and the erection column 24 on the insulating frame 20 can convenient being assemblied in insulating frame 20 on the stator core 10.
The utility model mouse cage type motor stator, axial end at stator core 10 is provided with the insulating frame made from insulating material 20, insulating frame 20 is provided with the through hole 21 that the wire casing 11 with stator core 10 matches, in the wire casing 11 of stator core 10 during winding around, earlier insulating frame 20 is fixed on the stator core 10, then coil is wrapped in the wire casing 11 of stator core 10 and in the through hole 21 of insulating frame 20, at this moment, expose the leakage current that between the coil of stator core 10 axial ends and stator core 10, produces, will be insulated frame 20 and isolate, just can not produce the leakage current transmission between coil and the stator core 10.
