Abstract
The invention discloses a motor stator. In a motor stator formed in the way that windings are wound around multiple magnetic poles embedded in an annular magnet yoke in the radial direction through an insulating component to form polyphase windings, to avoid overlapping or contact of multiple connecting lines used for connecting the windings, it is necessary to arrange other insulating components between the connecting lines, and therefore the price of the stator is increased. According to the motor stator, overlapping or contact of multiple connecting lines is avoided by means of a simple structure; multiple steps in different heights are arranged on part of flanges, extending in the axial direction, on the outer side of an insulating component used for winding and installation of windings, and connecting lines for each phase of windings are formed on and connected to the corresponding positions of the steps in the same height.

Technical field
The present invention relates to a kind of stator of motor, particularly about the stator forming polyphase windings.
Background technology
According to Fig. 6 to the content of prior art, form and be described.Fig. 6 is the stereogram of the structure of the stator representing the motor that prior art is implemented, radially be implanted on the multiple magnetic poles in circular yoke, by the stator insulation component 10 formed by resin, multiple winding 4 is reeled respectively, the end of each winding to next winding connecting line 13 along the flange 11 of the insulation division material 10 of isolated each winding outer felt around, due to the relation of winding wiring, each connecting line is actually overlapping to each other, cannot avoid the state producing contact.
Summary of the invention
As previously discussed, structure due to prior art does not consider the overlap or contact of avoiding connecting line, in order to keep dielectric strength, to be forced to time that is mutually isolated for connecting line, particularly spended time energy addition of between connecting line by other insulating components etc.
Motor stator in the present invention, improves the insulating component that uses and the part of flange that extends along the direction of principal axis of its outboard flanges defines and has the such structure of each highly different step.In the position corresponding with each step, define and connect respectively and form the guide portion of the connecting line of the winding of a phase.Or the guide portion of this connecting line, also can be increased in the outside of outboard flanges with suitable spaced multiple kick or ditch.
In order to solve the problem, the invention provides a kind of motor stator, radially be implanted on the multiple magnetic poles in circular yoke, by insulating component, each winding is wound around installation, formation polyphase windings, a part for the flange that the outboard flanges of described insulating component axially extends arranges and forms each highly different step, guide on the position that the step identical with each is corresponding, connect respectively and form the connecting line of the winding of a phase.
Preferably, the connecting line of the flange part outer peripheral face of described insulating component guides is be made up of the multiple kicks along the circumferential direction extended.
Preferably, the connecting line of the flange part outer surface of described insulating component guides is be made up of the multiple ditches along the circumferential direction worn.
Preferably, the end connecting line of the stator winding of each phase, by the step of each insulating component described with in the connecting line guiding that each flange outer sides is formed, makes the connecting line of each phase coil group isolate and keeps fixing.
In structure described above, owing to installing at winding and fixing in the process of each winding, isolation can be kept each other definitely by each connecting line of guide portion formed at flange part, the stator not having the high winding of the reliability of the sorrow of insulation fault to be formed can be obtained.

Embodiment
By the following drawings, embodiments of the invention are described.Fig. 1 is the stereogram representing the 1st embodiment in the present invention; Fig. 2 is from the front view viewed from direction of principal axis; Fig. 3 is the expanded view of the shape in the outboard flanges portion 3 representing stator insulation component 2, and the number of magnetic pole is 6, forms 3 phase windings.
Fig. 3 flange be numbered 3-1 to 3-6, the one-sided height of each flange is provided with step, respectively at the left side height of formation b of the flange of left side height of formation b, 3-3 of the flange of left side height of formation a, 3-2 of the flange of 3-1, or form the height a identical with 3-1 on the right side of the flange of 3-4, at the right side of the flange of the 3-5 formation height b identical with 3-2, form the height c identical with 3-3 on the right side of the flange of 3-6.
Fig. 2 is that the insulating component 2 shown in Fig. 3 is arranged on stator core 1, the front view that the axis that winding is provided with the stator of winding on each magnetic pole is seen, wherein, for making to form the 1st phase by winding 4-1 and winding 4-4, the 2nd phase is formed by winding 4-2 and winding 4-5, the 3rd phase is formed by winding 4-3 and winding 4-6, connect the connecting line 4-10 of winding 4-1 and winding 4-4, coordinate with the step a of each a height of flange 3-1 and flange 3-4, the outside being wound in flange is configured, similarly, connect the connecting line 4-10 of winding 4-2 and winding 4-5, coordinate with the step b of each b height of flange 3-2 and flange 3-5, the outside being wound in flange is configured, connect the connecting line 4-10 of winding 4-3 and winding 4-6, coordinate with the step c of each c height of flange 3-3 and flange 3-6, the outside being wound in flange is configured.Therefore, each highly different step a, b and c that the connecting line 4-10 due to each phase and the outboard flanges at insulating component 2 are arranged coordinate, are wound around, and maintain the interval of connecting line, make it not contact.
Fig. 4 is the end view of other embodiments representing stator of the present invention.In the outside of the outboard flanges of insulating component 2, be provided with the multiple kicks 5 along the circumferential direction extended, make between connecting line isolated, owing to arranging with identical spacing in the outside of all flanges, each flange is kept to the state of the isolation of adjacent connecting line, therefore really can isolate.This kick 5 matches with the position of the step of flange as shown in Figure 3 and configures, and really can isolate connecting line and configure.
