Abstract
The utility model relates to a coil structure of a wound rotor, which comprises a rotor sheet body. A semi-closed arc notch and a square slot bottom are punched on the rotor sheet body, and two or three rotor winding conducting bars are simultaneously arranged in a slot in parallel. As for the semi-closed arc notch of the rotor coil structure, only a space for embedding a conductor element into the slot is arranged, the surface loss of an iron core and the loss of in-tooth pulse vibration can be reduced, therefore, the length of an effective air gap can be reduced and a power factor can be improved. The two or three rotor winding conducting bars are simultaneously arranged in the slot in parallel, so that the technique difficulty in forming coils in a condition of not changing the electromagnetic property of a motor is reduced.
Description
Technical field
The utility model structure relates to wire-wound asynchronous motor rotor coil structure, is mainly used in the phase-wound rotor coil, takes into account operational characteristic when improving the motor electromagnetic performance.
Background technology
Motor is the device that electric energy and mechanical energy are changed mutually, is widely used in modern various machinery and the generating equipment.Wire-wound asynchronous motor, when its stator winding is received three-phase alternating-current supply, the three-phase current that flows into stator winding will produce a rotating magnetic field ripple with specific number of poles and rotating speed in air gap, this magnetic field " cutting " rotor winding will induce electromotive force and produce electric current in its sliver.
Every phase winding turns-in-series of the size of induced electromotive force and stator and rotor winding has direct relation in the rotor winding, and therefore in order to improve and to regulate motor properties, the rotor winding needs more element to form usually; But for reasons such as silicon steel sheet intensity, the rotor core circumferential surface sometimes again can not be towards too many groove.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, is guaranteeing to increase the phase-wound rotor loop construction of the every phase winding turns-in-series of rotor winding adjustable range under the punching mechanical strength acceptance condition thereby provide a kind of.
The technical solution of the utility model is as follows:
A kind of phase-wound rotor loop construction, comprise folded mutually rotor punching body, described rotor punching body upper punch is shaped at the bottom of semi-closure arc-shaped slot and the square groove, and the upper and lower layer in the groove of forming at the bottom of described semi-closure arc-shaped slot and the square groove embeds 2～3 roots rotor winding slivers simultaneously.
Its further technical scheme is: the openings of sizes of described semi-closure arc-shaped slot is for can only satisfy simultaneously with in the rotor winding sliver embedded groove.
And its further technical scheme is: the rotor winding sliver of parallel in banks is the active conductor component outline of separate series connection in the described groove, or the pattern side by side of same active conductor component outline.
Useful technique effect of the present utility model is:
The utility model is simple and reasonable for structure, and action effect is obvious; Under the situation that does not change structural material, guaranteeing by increasing the adjustable range of the every phase winding turns-in-series of rotor winding, to have improved induced electromotive force performance in the rotor winding under the silicon steel sheet intensity acceptance condition.The deep-slotted chip breaker opening is little, only reserves the space that a conductor element is embedded, and can reduce pulsation loss in surface loss unshakable in one's determination and the tooth, and effective air gap length is reduced, and power factor improves.According to rotor coil moulding difficulty, a conductor equivalence can be become two, three conductors side by side, under the condition that does not change the motor electromagnetic characteristic, reduced the technology difficulty of coil molding
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the enlarged drawing of A portion among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As shown in Figure 1, the utility model comprises mutually folded rotor punching body 1, and rotor punching body 1 upper punch is shaped at the bottom of semi-closure arc-shaped slot 2 and the square groove 4.As shown in Figure 2, wherein the opening of semi-closure arc-shaped slot 2 is only reserved the space in rotor winding sliver 3 embedded grooves.The interior upper and lower layer of 4 grooves of forming respectively has two to three row rotor winding slivers 3 at the bottom of semi-closure arc-shaped slot 2 and the square groove.In the present embodiment two row.The rotor winding sliver 3 of parallel in banks can be the active conductor component outline of separate series connection in the groove, also can be the pattern side by side of same active conductor component outline.
The operation principle explanation: semi-closure arc-shaped slot 2 openings of the utility model construction rotor punching body 1 are only reserved the space in the conductor element embedded groove, can reduce pulsation loss in surface loss unshakable in one's determination and the tooth, and effective air gap length is reduced, power factor thereby improve; During 3 assemblings of groove internal rotor winding sliver, can be one by one respectively by in the notch embedded groove.The rotor winding sliver 3 that has two or three parallel in banks in the groove simultaneously, make that on the one hand rotor punching body 1 groove number reduces, rotor punching tooth portion width increases, and is guaranteeing to have increased the adjustable range of the every phase winding turns-in-series of rotor winding under the condition that the silicon steel sheet mechanical strength is guaranteed; Reduce the overall dimension of rotor winding sliver 3 on the other hand, reduced the technology difficulty of rotor coil moulding.
Above-described only is the preferred implementation of the utility model structure, and the utility model is not limited to above examples of implementation.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from spirit of the present utility model and design, all should think to be included within the protection range of the present utility model.
