Abstract

The invention discloses a stator which comprises a tooth part and a yoke part installed on the tooth part, wherein the tooth part is provided with a plurality of coiling teeth and coiling grooves formed among the coiling teeth and the tooth part or the yoke part is provided with a boss which extends towards the coiling grooves in a protruding mode. Compared with the prior art, the stator has the advantages that the boss can abut against an insulation sleeve used for wire group coiling, a gap is formed between the insulation sleeve and the yoke part, and insulation materials are installed in the gap to prevent a coil from contacting the stator.

Description

A kind of stator

[technical field]

The relevant a kind of stator for motor of the present invention.

[background technology]

On April 2nd, 1993, Japanese kokai publication hei 5-83907 patent disclosure a kind of stator of monophase machine, it is for to be formed by stacking by some sheet silicon chips, each silicon chip is integral structure, the some teeth portion that it comprises a circular bridge joint and is connected in bridge joint, tooth portion is evenly distributed in the outer ring of bridge joint, some grooves are formed between the tooth portion, winding forms from the peripheral inwardly coiling of stator, changed traditional from the outside winding mode of stator interior, the effect of this stator: the coiling extension elongation that can reduce to be in stator end, increase the coiling automaticity, improve the utilance of copper cash, but in coiling line group process, the line group is contacted with stator, be unfavorable for that motor uses for a long time.

Therefore, be necessary to provide a kind of new stator to overcome the problems referred to above.

[summary of the invention]

Main purpose of the present invention is to provide simple in structure, the high stator of coiling line group effect.

For achieving the above object, the present invention can adopt following technical scheme: a kind of stator, it comprises tooth portion and is installed on yoke portion in the described tooth portion, described tooth portion has some coiling teeth and is formed at winding slot between the described coiling tooth, and described tooth portion or described yoke portion have the boss that protrudes out towards described winding slot.

Compared with prior art, the beneficial effect of stator of the present invention is: stator structure is simple, finishes the coiling winding efficiently, and boss can support the insulating case for coiling line group, have the gap between insulating case and the yoke portion, insulating material is installed in the gap is avoided winding to contact with stator.

[embodiment]

Please refer to 1 to Fig. 4, the present invention is a kind of stator 1, be used for alternating current machine, it comprises tooth portion 11 and is installed on yoke portion 12 in the tooth portion 11, tooth portion 11 has some coiling teeth 112, is formed at the winding slot 113 between the coiling tooth 112 and the boss 10 that protrudes out towards winding slot 113, and in other embodiments, boss 10 is not limited to and is positioned in the tooth portion 11, boss 10 can be positioned in the yoke portion 12, and namely boss 10 protrudes out to winding slot 113 from yoke portion 12.The boss 10 of stator 1 of the present invention is not limited to size, and as shown in Figure 5, the volume of boss 40 is bigger, and this boss 40 is connected in coiling tooth 112, and the function of the function of boss 40 and boss 10 is roughly the same, and boss 40 can make the performance of stator 1 stronger.

The integral structure that yoke portion 12 forms by punching press, it comprises outer surface 121, reaches the holddown groove 123 that outwards is recessed to form from yoke portion 12 inner surfaces with outer surface 121 interior surface opposing 122.Tooth portion 11 also comprises the fixed part 146 that is installed on holddown groove interior 123, and boss 10 is positioned on the fixed part 145.In other embodiments, boss 10 protrudes out in winding slot 113 from yoke portion 12 inner surfaces 122.

On at least one locating piece 146 settings and the fixed part 145, a corresponding location notch 124 arranges and yoke portions 12, and locating piece 146 is contained in the location notch 124.Certainly, locating piece 146 can be positioned in the yoke portion 12, and location notch 124 is positioned on the fixed part 145.

Coiling tooth 112 comprises some crooked teeth 14 and straight-tooth 15, and crooked tooth 14 comprises the connecting portion 141 that is positioned at inner edge, from connecting portion 141 outward extending first extensions 142, from first extension, 142 oblique outward extending second extensions 143, from second extension, 143 outward extending the 3rd extensions 144.Fixed part 145 is from 144 horizontal expansions of described the 3rd extension.Fixed part 145 is from 144 horizontal expansions of the 3rd extension.The crooked tooth 14 of straight-tooth 15 both sides is roughly along same straight-tooth 15 mirror images.

One insulating case 2 is installed on stator 1, and boss 10 supports insulating case 2 and makes formation one slit between described yoke portion 12 and the insulating case 2 (indication), and insulating material (not shown) is installed in the described slit.Insulating material comprises the material of all insulation, comprises insulating paper, insulating trip etc.

Also have on the stator 1 and be wound in first winding 31 on a pair of second extension 143 and be wound in second winding 32 on a pair of the 3rd extension 144, boss 10 is positioned at this to the outside of the 3rd extension 144.First winding 31, second winding 32 are wound on the insulating case 2, and insulating case 2 makes first winding 31, second winding 32 not touch in the tooth portion 11, and insulating material makes second winding 32 not touch yoke portion 12.The insulating case 2 of its elsewhere of aspect ratio of the insulating case 2 around at boss 10 places is low, and like this, lower insulating case 2 does not hinder coiling second winding 32.So simple in structure, the effect that improves coiling line group of this stator 1.Simultaneously, when on the coiling insulating case 2 when first winding 31, second winding 32, boss 143 supports insulating case 2, makes insulating case 2 stressed rationally, is not easy to be fractureed.
