Description
Technical field
The utility model relates to a kind of motor stator.
Background technology
The cabling mode of a kind of motor stator lead-in wire of prior art; Motor is for reaching high copper factor to improve electric efficiency; Adopt centralized winding (coil is wrapped on the single stator tooth) through regular meeting, in this motor, stator comprises stator core, coil rack and winding; Coil rack is assemblied on two axial ends of stator core, and winding just is wound on stator core and the coil rack.After coiling finished, lead-in wire was drawn from winding, is connected on its corresponding control circuit board.Be designed with along the circumferential direction equally distributed protrusion on the coil rack periphery of this kind design, lead-in wire from winding, draw the back through the protrusion on the coil rack periphery around overlap joint on coil rack, final three lead-in wires compile the location, back.
Above-mentioned coil rack is succinct neat for lead-in wire is arranged, so increased equally distributed protrusion in outer peripheral sidewall, this design has increased the difficulty of coil rack Mold Making, has also increased cost of manufacture.
In addition, in order to prevent the wiring of above-mentioned lead-in wire and correspondingly to need miscellaneous part, so components number has increased.In addition, it is very bothersome to utilize the harness line to carry out the harness operation.
The utility model content
The utility model provides a kind of motor stator, has solved the problem of swing of motor stator lead-in wire or landing, and has reduced cost of manufacture.
The utility model provides a kind of motor stator; Said stator comprises stator core, coil rack and winding; Said coil rack is two; Said two coil racks are arranged at respectively on the both ends of the surface of axis direction of said stator iron core and are opposed each other, and said winding is wound on said stator core and the coil rack; Said coil rack comprises annulus, tooth portion and periphery wall portion, and said tooth portion is outstanding to radially inner side from the inner peripheral surface of above-mentioned periphery wall portion, and along circumferentially predetermined space ground arrangement; Extend axially in above-mentioned periphery wall portion and to be provided with the location division, arrange along circumferential predetermined space said location division, and said each location division is provided with two sides, and at least one side is provided with stage portion, is provided with concave part in the middle of the adjacent stage portion.
Preferably, said winding is provided with three lead-in wires, and two outer leg in said three lead-in wires are led to the outer circumferential side of said periphery wall portion respectively, and after at least one concave part on the different location divisions twines, converges middle leads separately.
Preferred, each stage portion increases to the direction near stator core gradually.
On the location division of the coil rack that directly is wrapped in the utility model with going between, make the utility model need not increase unclassified stores such as harness line; The location division is designed on the extended surface of surrounding wall portion outside, also need do not increased the Mold Making cost; The utility model can be firm lead-in wire is fixed on the coil rack, prevent lead-in wire swing or landing.

Embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Below in conjunction with accompanying drawing and embodiment the utility model is done and to be further described.
Of Fig. 1 to Fig. 5; A kind of motor stator; Said stator 100 comprises stator core 10, coil rack 20 and winding 30; Said coil rack 20 is two, and said two coil racks 20 are arranged at respectively on the both ends of the surface of axis direction of said stator iron core 10 and are opposed each other, and said winding 30 is wound on said stator core 10 and the coil rack 20; Coil rack 20 avoids stator core 10 directly to contact with winding 30 between stator core 10 and winding 30, and both are isolated each other.Said coil rack 20 comprises annulus 201, tooth portion 202 and periphery wall portion 203, and annulus 201 plays the effect that stops coil, winding around in the tooth portion 202, and periphery wall portion 203 plays and stops that coil skids off and the effect of the lead-in wire of arranging.Said tooth portion 202 is outstanding to radially inner side from the inner peripheral surface of above-mentioned periphery wall portion 203, and along circumferentially predetermined space ground arrangement; Extend axially in above-mentioned periphery wall portion 203 and to be provided with location division 204; Said location division 204 is along circumferentially predetermined space arrangement; Said each location division 204 is provided with two sides, and at least one side is provided with stage portion 2041, is provided with concave part 2042 in the middle of the adjacent stage portion.
Said winding 30 is provided with three lead-in wires 40, and two outer leg of said three lead-in wires in 40 are led to the outer circumferential side of said periphery wall portion 203 respectively, and after the concave part on the different location divisions 204 2042 twines, converge middle leads 403 separately.
Concrete; First lead-in wire, 401, second lead-in wire 402 and middle leads 403, the first lead-in wire 401 and second that three lead-in wires 40 are respectively two outsides go between 402 from winding space, pass after, bend towards the outer circumferential side of the periphery wall portion 203 of coil rack 20 respectively; And, the concave part on the different location divisions 204 2042 converges middle leads 403 after twining separately; Three go between 40 twisteds together, and lead-in wire 40 swings after can preventing to erect are inserted lead terminal in the wire harness housing 50 respectively then.Walk line process if lead-in wire 40 needs around more than half circumference, can just advance several grooves that twine more, the not enough and absent-mindedness landing of the 40 long pulling force that prevent to go between.
Each stage portion 2041 increases to the direction near stator core gradually., help winding leads 40 cablings and wiring like this.
On the location division of the coil rack that directly is wrapped in the utility model with going between, make the utility model need not increase unclassified stores such as harness line; The location division is designed on the extended surface of surrounding wall portion outside, also need do not increased the Mold Making cost; The utility model can be firm lead-in wire is fixed on the coil rack, prevent lead-in wire swing or landing.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
