Abstract
The utility model discloses a kind of motor stator punching, comprise yoke portion, teeth portion, stator slot and centre bore, described stator slot comprise several centrally hole circle circumferential direction distribution vat and sulculus, described sulculus is the semi-open slot that top seal, bottom and centre bore connect, described vat is closed closed slot and centrally hole circle circumferential direction is uniform in pairs, described sulculus with several be listed as one group centrally hole circle circumferential direction be distributed between described paired vat.Described stator punching is annular, described sulculus preferably with four be listed as one group centrally hole circle circumferential direction be distributed between described paired vat.Teeth portion between described paired vat is stator commutating pole, and the teeth portion between described sulculus arranged side by side and the teeth portion between vat and sulculus are stator main pole.The utility model reduces motor volume and spark produces probability, improves silicon steel sheet magnetic loading utilance, and is conducive to the commutation of direct current machine.
Description
Technical field
The utility model relates to a kind of stator of motor, particularly relates to a kind of stator punching of motor.
Background technology
Along with industrial expansion, the integration degree of Technology for Modern Equipment improves constantly, and from the angle of motor, due to the restriction of installing space, needs, when keeping motor performance, to reduce the size of motor as far as possible.Therefore, in the urgent need to a kind of novel stator laminating structure, when performance is constant, the volume of motor can be reduced.
Existing motor stator punching, a kind of structure disclosed in Chinese utility model patent ZL201220422630.4, it comprises stator yoke, be positioned at the rotor hole at stator yoke center, line embedding groove, the outline cross section of described stator yoke is rectangle, lateral dimension is less than longitudinal size, line embedding groove is distributed on rotor hole circumferentially, the notch of line embedding groove is semiclosed mouth and is positioned at rotor hole circumferentially, described line embedding groove always has 24, be respectively 16 vats 32, 4 middle slots 34, 4 sulculuses 36, wherein 16 vats 32 are divided into two groups, be arranged on just to the position of the transverse direction of stator yoke respectively continuously, 4 middle slots 34 are divided into two groups, be separately positioned on the position of adjacent vat 32, 4 sulculus 36 deciles two groups, be separately positioned on just to the position of the longitudinal direction of stator yoke, also be vat 32, middle slot 34, sulculus 36 is sequentially symmetrical arranged.The stator punching not only complex structure of this structure, and there is the larger-size shortcoming of motor volume.
Summary of the invention
The technical problems to be solved in the utility model is to provide one can reduce motor volume, is beneficial to commutation, and can reduce the motor stator punching that spark produces probability.
For solving the problems of the technologies described above, the utility model adopts so a kind of motor stator punching, comprise yoke portion, teeth portion, stator slot and centre bore, described stator slot comprise several centrally hole circle circumferential direction distribution vat and sulculus, described sulculus is the semi-open slot that top seal, bottom and centre bore connect, described vat is closed closed slot and centrally hole circle circumferential direction is uniform in pairs, described sulculus with several be listed as one group centrally hole circle circumferential direction be distributed between described paired vat.
In the utility model, described stator punching is annular, described sulculus preferably with four be listed as one group centrally hole circle circumferential direction be distributed between described paired vat.
In the utility model, the teeth portion between described paired vat is stator commutating pole, and the teeth portion between described sulculus arranged side by side and the teeth portion between vat and sulculus are stator main pole.
After adopting said structure, the utility model has following beneficial effect:
Because the utility model employs the structure of integration, main pole separated in prior art and commutating pole are placed in same stator laminating structure, therefore make the volume of motor be reduced.
Main pole and commutating pole are placed in a stator punching by the utility model simultaneously, and the magnetic property of stator silicon steel sheet can be fully utilized, and improve silicon steel sheet magnetic loading utilance.
The utility model is conducive to the commutation of direct current machine, reduces the probability that spark produces.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is a kind of structural representation of the utility model motor stator punching.
Embodiment
A kind of motor stator punching shown in Figure 1, comprise yoke portion 1, teeth portion, stator slot and centre bore 2, described stator slot comprise several centrally hole 2 circumferencial direction distribution vat 3 and sulculus 4, the semi-open slot that described sulculus 4 is top seal, bottom and centre bore 2 connect, described vat 3 be close closed slot and centrally hole 2 circumferencial direction is uniform in pairs, described sulculus 4 with several be listed as one group centrally hole 2 circumferencial direction be distributed between described paired vat 3.
As a kind of preferred embodiment of the present utility model, as shown in Figure 1, described stator punching is annular, described sulculus 4 with four be listed as one group centrally hole 2 circumferencial direction be distributed between described paired vat 3.
In the utility model, the teeth portion 5 between described paired vat 3 is stator commutating pole, and the teeth portion 6 between described sulculus 4 arranged side by side and the teeth portion 7 between vat 3 and sulculus 4 are stator main pole.
See Fig. 1, the utility model when mounted, placed main pole coil and commutation coil in vat 3 simultaneously, wherein, places commutation coil near teeth portion 5 part, places main pole coil away from teeth portion 5 part.All main pole coil is placed in sulculus 4.
Through on probation in motor, the utility model reduces motor volume and spark produces probability, improves silicon steel sheet magnetic loading utilance, achieves good effect.
