Description

Brushless motor stator winding Volume winding apparatus

The utility model is the device that relevant Volume uses around stator winding, especially brushless motor stator winding Volume winding apparatus.

As everyone knows, exchange and direct current brush motor, by the rotor that is arranged on inside center with surround that its stator constitutes, and its rotor rotates in stator center.

Usually, electromotor on the garden cylinder of wall, along axially having wire casing, is embedded with winding at groove, so as to forming induced field within it.To the wire casing rule, not only waste time and energy but also need complex apparatus.In addition, because the existence of the groove tooth of projection, formed magnetic field is not continuous, and it also limits the quantity of winding, influences the efficient of motor.

Once proposed for this reason, and be paved with winding on the total inner surface of stator, the effective turn to guarantee that motor needs so as to raising the efficiency, reduces magnetic hysteresis loss.One of them example is No. the 5197180th, United States Patent (USP).

Present briefly above-mentioned once United States Patent (USP).At first having got section ready is hexagonal coiling mould; Wherein there is other limit of a pair of side ratio that faces toward mutually to grow.After the outside of this coiling mould Volume three utmost point phase windings, remove to take out this coiling mould.Take out after the coiling mould,, flatten, make it become a flat dual form with oblique a little direction the winding of form as the moulding of coiling mould.Then, two ends are gathered into folds, it is cylindric that Volume becomes, and makes it form a stator winding.The external diameter of this winding gets the stator that can insert motor, and its internal diameter gets and can insert rotor.This method can be paved with total inner surface with winding under the situation that stator is not slotted, can reach the purpose that improves moyor etc.Yet its percent defective is very high.For preventing this situation, must need accurate and special equipment.That is, on the coiling mould after the coiling winding, in the process of flattening, if once the uniformity that can remove to destroy winding accidentally and regular Volume around state, be twisted into the tangled skein of jute.This result causes fatal influence can for the performance of motor.If carry out the moulding of tubular again, internal diameter after the moulding and external diameter can be inhomogeneous so, thereby before being assembled into motor, internal external diameter to carry out once necessary finishing, and this just needs extra equipment and operation.Because the existence of these problems, above-mentioned United States Patent (USP) although the strong point that improves motor performance is arranged, in the adverse consequences that time, manpower, equipment etc. bring production efficiency, fails to be applied.

In view of the problem of above-mentioned existence, the purpose of this utility model provides that a kind of making apparatus is simple, producing cost and percent defective are all lower and the brushless motor of dependable performance with stator winding Volume winding apparatus.

The purpose of this utility model is achieved by the following technical solution: it comprises by its external diameter is can make rotor rotation and have the Volume tube mould that the cylinder of diameter of stator bore size constitutes, the cylinder of this Volume tube mould has the working hole at perforation center, have several pocket for the punch heads from two ends by certain distance with the angle of equalization, in the inside of each pocket for the punch head the hook that can haunt simultaneously is housed, is provided with the thimble that hook is haunted at the two ends of working hole.

The utility model has the advantages that at the coiling brushless motor with in the stator winding, stator winding with traditional different shape is provided, as long as going up, Volume just can directly be used for assembling motor, do not need the outer operation of supplements, can produce very easily and assemble, thereby can increase substantially labor productivity, reduce producing cost and percent defective, improve the quality of products.

Below in conjunction with accompanying drawing instantiation is elaborated.

Fig. 1 is the utility model perspective view.

Fig. 2 is the front view of Fig. 1.

Fig. 3 is the sectional drawing of Fig. 1.

Fig. 4 is the operating state sectional drawing of Fig. 3.

Fig. 5 is the enlarged drawing of A--A directional profile among Fig. 3.

Fig. 6 is support ring and a hook structure schematic diagram in the utility model.

Fig. 7 be utilize the utility model carry out Volume around expanded view.

Fig. 8 is the stator winding structure schematic diagram that utilizes the utility model coiling.

The utility model is provided with Volume tube mould 1, and it is outer through being that the cylinder that can make the rotor rotation and have a diameter of stator bore size constitutes by one for it; This cylinder has the working hole 2 at perforation center; Be provided with the thimble 20 that to advance and retreat at the two ends of working hole 2.

At the two ends of Volume tube mould 1,, leave several pocket for the punch heads 3 with the angle of equalization by certain distance; The hook 10 that can play the hook effect is housed in the inside of each pocket for the punch head 3; The rear end of each hook 10 is provided with supported hole 11, and is assembled into the radiation form with this hole on support ring 15; Have at the inboard partially outer surface of supported hole 11 and to push back mouthfuls 12, and be provided with working face 13 in its relative the inside.

Front end at hook 10 forms one 90 hook more than the degree, when forming level with box lunch hook 10, makes the outside of its outstanding Volume tube mould 1.

With the outer surface that pushes back mouthful 12 corresponding Volume tube moulds 1 of hook 10, leave and push back groove 4, packing into then pushes back ring 5 as what the elastomeric material of rubber-like was made, makes hook 10 be subjected to pointing to the centripetal force at the center of Volume tube mould 1.

In addition, insert the thimble 20 of working hole 2, be provided with the operate portions 21 that diameter equals working hole 2 in its front portion, be provided with cone portion 22 in its terminal.

Not elsewhere specified in the drawings bis 30 is stator winding that coiling is over, 31 and 31 ' be insulating tape; C1, C2, C3 are each utmost point phase windings.

Below with the use order, be elaborated with regard to the effect of each structure of the utility model.

Originally, in Volume tube mould 1, thimble 20 is in released state; When thimble 20 to jacking, cone portion 22 will promote hook 10 working face 13 and make whole hook 10 become level so; When operate portions 21 arrives working faces, link up with 10 so and will become level fully, and make its front end give prominence to outside fully at Volume tube mould 1.

Utilize this projection hook 10 before bring in Volume around winding.From launching Volume as can be known around Fig. 7 of state, along Volume tube mould 1 vertically, drawing rectangular track carry out Volume around.Earlier with a utmost point phase winding facing to one by a pair of hook 10 vis-a-vis and the hook 10 formed rectangles that face toward across another two-phases of several neutral gears at its other Side, Volume winding number circle; Then, again in connection with and by the formed rectangle of identical neutral gear, Volume winding number circle again; Whole surface with the full Volume tube mould 1 of the method Volume; But will be in a clockwise direction with counterclockwise replacing mutually carry out Volume around.

Then Volume around other utmost point phase winding (C2, in the time of C3), be on the position of certain angle of staggering, according to above-mentioned method carry out Volume around.

When Volume after ending, withdraw thimble 20, what push back so that ring 5 will press hook 10 pushes back mouth 12, makes whole hook 10 imbed the inside of Volume tube mould 1, thereby can make Volume around stator winding 30 separate with Volume tube mould 1.Can obtain the stator winding of form such as Fig. 8 thus.
