Abstract
The utility model relates to a magnetic pole component of a DC motor without a brush. In the utility model, the margin of the pole surface of a magnetic pole piece is provided with a bending arc-shaped bending section which is embedded into the notch position of a stator seat, and the height of the bending section is not bigger than the thickness of the disk surface of the stator seat; the stator seat is provided with a support foot and a barb which are used for being reversely buckled with holes of an electronic basal plate to form the combining action, when the stator seat is wound with coils, conducting wires can not be damaged.
Description
The utility model relates to a kind of magnetic pole component of brushless d.c. motor, and the arc portion that is had with the pole-face edge of pole piece cooperates the breach of stator seat, makes stator seat when winding around, and lead can not suffer damage.
On the stator seat of brushless d.c. motor, tens of microns the copper enamel-cover conductor that adopts thin as hair in order to the coil windings that produces rotating magnetic field is as the coiling material, because the unusual softness of this enamel-cover lead is easy to sustain damage, and causes the running of motor bad.
The U.S. 4,891, in No. 567 patent cases, the pole-face of its pole piece and pole piece itself are vertical bending kenel, make the pole-face cover of pole piece in the outer rim of stator seat coil; Therefore, after it certainly will be finished the coil windings coiling of stator seat earlier, punching press assembling pole piece go again on stator seat, yet in this kind operating type, when punching press fixed magnetic pole sheet is on stator seat, the as easy as rolling off a log coil windings broken string that causes, and also be easy to oppress the coil windings in the stator seat, the insulating barrier of enamel-cover lead is damaged, make coil windings be subjected to cranking current pulse for a long time, in the course of time, very easily cause the rapid deterioration of coil windings, cause motor running bad, shorten the useful life of motor.
In view of this, the purpose of this utility model is to provide a kind of magnetic pole component of brushless d.c. motor, it has the pole piece structure of bend with the edge, the relief configuration that cooperates stator seat, make the stator structure and the coil windings operation of Brushless DC motor, more attain, and can reduce the fraction defective of motor in rationalization.
For achieving the above object, the magnetic pole component of the brushless d.c. motor that the utility model provides, its two sides in stator seat respectively are provided with pole piece, pole piece combines with hole and projection mutually with stator seat, pole piece and stator seat center respectively are provided with axis hole, can place wherein for the metal central siphon in the axis hole, the jack-post external diameter of stator seat can be for the coil windings coiling thereon; The pole-face edge of this pole piece has the bend of curved arc shape, and the height of this bend is less than the thickness of stator seat card.
The crooked position that this stator seat is matched with pole piece installs jagged.
This stator seat is provided with leg, and barb is arranged on the leg, and leg can peak at the surface of electric substrate, and barb then can pass the hole of electric substrate, and left-hand thread forms combination in the reverse side of electric substrate.
Now cooperate and consult accompanying drawing, details are as follows with preferred embodiment with the utility model:
Fig. 1: three-dimensional exploded view of the present utility model.
Fig. 2: vertical view of the present utility model.
Fig. 3: cut-away section end view of the present utility model.
See also shown in Figure 1ly, pole piece 1 of the present utility model is in the pole-face edge, utilizes impact style to curve to have the bend 11 of curved arc shape; On this pole piece 1 and be provided with combined hole 12 and axis hole 13.
The center of stator seat 2 is provided with jack-post 24, and jack-post 24 inside are provided with axis hole 25, and jack-post 24 external diameters then can twine on it for coil windings.After the axis hole 13 of the axis hole 25 involutory upper and lower pole pieces 1 of stator seat 2, can be placed through wherein for metal central siphon 3.Axis hole in the metal central siphon 3 wears for the rotating shaft of rotor 5 again.
Shown in Fig. 2,3, pole piece 1 is incorporated into after the stator seat 2, and the bend 11 of pole piece 1 is positioned at the breach 21 of stator seat 2, and bend 11 is towards the card bending of stator seat 2, and the height of bend 11 is the best with the card thickness less than stator seat 2.
After pole piece 1 was finished with stator seat 2 and 3 assemblings of metal central siphon, the external diameter of the jack-post 24 of stator seat 2 just can be for coil windings 23 coilings.And because the edge of pole piece 1 is a bend 11, and it is no more than the thickness of stator seat 2 cards highly again, and therefore, during coiling, the enamel-cover lead does not have and cut off or bad problem that the insulation enamelled coating of lead is damaged.And after coiling is finished, just there is not the bad work flow of punching press compressing enamel-cover lead again.Therefore,, and improve normal useful life, suitable benefiting all arranged for the fraction defective attenuating of brushless d.c. motor.
In sum, the utlity model has practicality and creativity, be not indicated in any publication when knowing.
