And in the production process of motor, need people to be wrapped on the stator of motor by copper cash, and the quantity being wrapped in motor or epitrochanterian copper cash just can affect the watt level of motor.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is the stator providing a kind of single-phase permanent multipolar dynamo.
For achieving the above object, the utility model provides following technical scheme: a kind of stator of single-phase permanent multipolar dynamo, form by several stator punchings are stacking, described stator punching is provided with centre bore and some wire-wound grooves, described wire-wound groove takes the shape of the letter U, the opening of described wire-wound groove is towards stator punching pivot, and described wire-wound bottom land end is arc-shaped, and the extended line of wire-wound groove sidewall intersects in centre bore; Form canine tooth between described adjacent wire-wound groove, described canine tooth is provided with some little teeth.
Preferably, described wire-wound groove sidewall is tangent with the wire-wound bottom land end in circular arc.
Preferably, sulculus is formed between the described little tooth be arranged on same canine tooth; The facewidth of described little tooth is a1, and the groove width of described sulculus is a2; The ratio of described a2/a1 is 1.1/1 to 1.3/1.
Preferably, described stator punching outer shroud is provided with some recessed teeth, is provided with location notch in a described recessed tooth.
Preferably, described stator punching is made up of silicon steel sheet.
Compared with prior art, the beneficial effects of the utility model are: when by neat for some stator punchings being stacked, just can form the stator of single-phase permanent multipolar dynamo, the wire-wound groove on some stator punchings be stacked so just can be made to connect, thus be conveniently wound around copper cash, and the shape of the wire-wound groove described in the utility model can increase the volume of wire-wound groove greatly, thus more copper cash can be wound around, thus improve output effect of motor.

Embodiment
Referring to figs. 1 through Fig. 3, the nanostator embodiment of the utility model single-phase permanent multipolar dynamo is described further.
A kind of stator of single-phase permanent multipolar dynamo, by several, stator punching 1 is stacking forms, described stator punching 1 is provided with centre bore 11 and some wire-wound grooves 12, described wire-wound groove 12 takes the shape of the letter U, the opening of described wire-wound groove 12 is towards stator punching 1 pivot, described wire-wound groove 12 bottom is arc-shaped, and the extended line of wire-wound groove 12 sidewall intersects in centre bore 11; Form canine tooth 13 between described adjacent wire-wound groove 12, described canine tooth 13 is provided with some little teeth 131.When by neat for some stator punchings 1 being stacked, just can form the stator of single-phase permanent multipolar dynamo, the wire-wound groove 12 on some stator punchings 1 be stacked so just can be made to connect, thus be conveniently wound around copper cash, and the shape of the wire-wound groove 12 described in the utility model is wire-wound groove 12 bottom is arc-shaped, the extended line of wire-wound groove 12 sidewall intersects in centre bore 11, so just greatly can increase the volume of wire-wound groove 12, thus more copper cash can be wound around, thus improve output effect of motor.
And make the sidewall of wire-wound groove 12 from the bottom of wire-wound groove 12, draw close gradually, thus reduce the opening of wire-wound groove 12, so just can when winding copper cash, can effectively prevent the copper cash be wrapped in wire-wound groove 12 from departing from wire-wound groove 12, make the winding work of copper cash more easily good, substantially increase production efficiency.But also greatly can increase the projected area of canine tooth 13, thus increase the intensity of canine tooth 13, and more little tooth 131 can be set, thus increase field pole, more magnetic field can be cut to when rotor so just can be allowed to rotate, thus greatly strengthen the transmission power of motor.
Described wire-wound groove 12 sidewall is tangent with wire-wound groove 12 bottom in circular arc.The inwall of wire-wound groove 12 can be made rounder and more smooth, thus can effectively prevent the copper cash be wrapped in wire-wound groove 12 from producing wearing and tearing.
Sulculus 132 is formed between the described little tooth 131 be arranged on same canine tooth 13; The facewidth of described little tooth 131 is a1, and the groove width of described sulculus 132 is a2; The ratio of described a2/a1 is 1.1/1 to 1.3/1.The ratio of a2/a1 is in 1.1/1 to 1.3/1 this interval, and its magnetic field intensity produced is the strongest, so just can make rotor after cutting magnetic induction line, can produce larger power output, greatly strengthen the result of use of motor.
Described stator punching 1 outer shroud is provided with some recessed teeth 14, is provided with location notch 15 in a described recessed tooth 14.Easily stator punching 1 can be stacked by recessed tooth 14, and can also conveniently be installed on the housing of motor, and be also provided with location notch 15 in a recessed tooth 14 wherein, staff so just can be made conveniently to distinguish the both forward and reverse directions of the stator having this stator punching 1 stacking, thus make people more easily stator is installed, handled easily, simplify the operation flow process, substantially increases the operating efficiency of staff.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
