Description

Motor silicon steel sheet molding structure

The utility model relates to a kind of motor silicon steel sheet molding structure, particularly relate to a kind of miniaturization that reaches, the rate of filling winding to flute height, winding operation is easy, and adopt integrated design, need not carry out tight fit and be pressed into operation, do not have the problem that the upper and lower silicon steel sheet orientation angle and the depth of parallelism can't accurately cooperate, can obtain maximum power output, gapped problem when also not having iron hoop and combining with the steel silicon chip, can make magnetic pole that complete loop circuit is arranged, and can not influence the motor silicon steel sheet molding structure of motor rotary speed.

Because information industry miniaturization day by day, central processing unit (CPU) and electronic building brick will produce high temperature in the process of working at high speed, need use the fan forced cooling, and fan motor also need meet requirements such as high efficiency, low unit price and volume are little.

At present, commercially available DC Brushless Motor stator roughly is divided into two kinds, as shown in Figure 1, a direct current brushless motor stator wherein, it is with the made silicon steel sheet 10a storehouse of permeability magnetic material with most, and twine the suitable number of turns in four limits with pitch of the laps 11a, so as to forming a direct current brushless motor stator, but its shortcoming has:

1, can't miniaturization.

2, rate of filling winding to flute is low.

3, coiling is difficult for.

As shown in Figure 2, another kind of DC Brushless Motor stator is iron hoop 20a in the middle of it, upper and lowerly engages with the made silicon steel sheet 21a of permeability magnetic material in the mode of closely cooperating, and between upper and lower silicon steel sheet 21a, be wound with the coil (figure slightly) of the suitable number of turns, but its shortcoming has:

1, upper and lower silicon steel sheet 21a and middle iron hoop 20a tight fit are pressed into difficult.

2, the upper and lower silicon steel sheet 21a orientation angle and the depth of parallelism can't be accurate, cause motor can't obtain maximum power output.

Gapped when 3, iron hoop 20a combines with silicon steel sheet 21a, at magnetic pole complete loop circuit can't be arranged, will influence motor rotary speed.

As seen, above-mentioned known motor silicon steel sheet on the manufacturing and actual the use, obviously has inconvenience and defective existence, and demands urgently being improved.

Main purpose of the present utility model is to provide a kind of motor silicon steel sheet molding structure, and it can make structure simplify significantly, can reduce cost, and reaches miniaturization effectively, and the rate of filling winding to flute height, and winding operation is also more or less freely.

Another purpose of the present utility model, be to provide a kind of motor silicon steel sheet molding structure, it adopts integrated design, need not carry out known on, the operation that following silicon steel sheet and middle iron hoop tight fit are pressed into, more do not have known on, the problem that the following silicon steel sheet orientation angle and the depth of parallelism can't accurately cooperate, therefore the utility model motor can be obtained maximum power output, and the utility model adopts integrated design, gapped problem when also not having known iron hoop and engaging with silicon steel sheet, therefore the utility model can have complete loop circuit at magnetic pole, and can not influence motor rotary speed.

Above-mentioned purpose of the present utility model is achieved in that a kind of motor silicon steel sheet molding structure, it comprises that a slice makes integrated silicon steel sheet with permeability magnetic material, this silicon steel sheet includes a body, this body upper and lower end respectively is connected with plurality of pins portion, the tooth portion that is located at top and bottom is complementary shape, these tooth portions bending 90 degree twist into cylindricly in this body, form a silicon steel structure that is applicable to the DC Brushless Motor stator whereby.

Below in conjunction with accompanying drawing shown in the embodiment feature of the present utility model and technology contents are described in further detail, however shown in accompanying drawing only for reference with the explanation, be not to be used for the utility model is limited.
