Background technology
The four-shaded pole motor comprises stator and rotor.Stator comprises the stator core that has four wire casings, and stator core is that silicon steel material is processed, and is wound with the enamelled wire coil that multiturn is made with 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 through 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.
Summary of the invention
Technical problem to be solved by this invention is, overcomes above deficiency, and a kind of four-shaded pole 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; Technical scheme of the present invention is: a kind of four-shaded pole motor stator; Comprise the stator core that has four wire casings; The axial end of said stator core is provided with the insulating frame of processing with insulating material, and said insulating frame is provided with the through hole that the wire casing with stator core matches.
Further, the axial end of said stator core is provided with a plurality of installing holes, and said insulating frame is provided with the erection column that matches with said installing hole.
Further; The excircle of said insulating frame is provided with corrugated outer circumferential edge; The inner periphery of said insulating frame is provided with corrugated internal circle; Said outer circumferential edge and internal circle are synchronous waveform, and the cross line of the minimum point of said outer circumferential edge is said through hole five equilibrium, the arc mid point of the excircle between vertical two through holes of the peak of said outer circumferential edge and the line in stator core axle center.
Further, the peak of said outer circumferential edge is bundling trough outside two side directions offer, and the peak of said internal circle offers interior bundling trough to two side directions.
Further, said outer bundling trough equates with the width of interior bundling trough.
The invention has the beneficial effects as follows: four-shaded pole motor stator of the present invention, be provided with the insulating frame of processing with insulating material at the axial end of stator core, 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 in the through hole with insulating frame, at this moment, exposes 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.
