Abstract

The utility model discloses an end fixing device of a motor rotor coil, which overcomes the defects that a motor goes wrong easily, and normal running of the motor is influenced in the prior art, and comprises a coil end part exposed out of an iron core, a weftless belt bound at the outer layer of the end part of the coil and a weftless rope bound at the initial position of the weftless belt, and the technical key points are as follows: protective rings are arranged at the periphery of the weftless belt and are fixedly connected through supporting rings on the iron core. Compared with the fixing method of a current coil, the end fixing device has a simple structure, is easy to manufacture, the integral strength of the end part of the coil is obviously enhanced, the distortion of the end part of the coil can be effectively avoided, the normal running of the motor can be ensured, and the sense of beauty of the end part of the coil can be improved.

Description

Motor-spin-coil end fixture

Technical field

The utility model relates to a kind of improvement to motor component rotor coil fixed structure, particularly a kind of the end winding that is exposed at the iron core outside is set up the motor-spin-coil end fixture that fixture is protected.

Background technology

Along with electromechanics trade develops rapidly, motor in the use of all trades and professions more and more widely.Especially the cement industry coiling electric motor forms and is first-selection because startability is good, detent torque is big, efficient is high, be convenient to control.The market demand of four hypervelocity coiling electric motors is increased sharply in recent years, and the high request of the security reliability of workmanship and use is displayed gradually.The rotor coil end of existing coiling electric motor is exposed at the fixing of iron core outside, is that the outer bondage of end winding is not had the latitude band, and the original position of no latitude band is tied up with no latitude rope.Because due to coil manufacturing and the inserting-coil process, the fixing height of end winding is difficult to accomplish in full accord, so the gap phenomenon may not occur when bondage has the latitude band, cause and water lacquer to handle the back outward appearance not attractive in appearance, cause simultaneously the end torsional deformation easily at the motor frequent starting and when running up, no latitude band is separated with end winding, is commonly called as " throw away ".In " bandage of rotor winding outer end and the binding method of winding outer end " as Chinese patent CN97111288.6, disclosed outer end bandage and binding method, though it has solved the fixing of the little rotor end of Low speed electric motor and rotor diameter, to the fixing defective that still has " being thrown away " of the big rotor end of pot motor and external diameter.Because of in the high speed coiling electric motor, there being more above-mentioned drawbacks, so motor is broken down, influence the normal operation of motor, can cause very big loss to the user.

The utility model content

The purpose of this utility model provides a kind of motor-spin-coil end fixture, the motor that easily makes that it has overcome the prior art existence breaks down, influence the defective of the normal operation of motor, itself and the immobile phase ratio of existing coil, simple in structure, easy to manufacture, remarkable intensifier coil end bulk strength, not only can avoid the end winding torsional deformation effectively, guarantee that motor normally moves, and increase the aesthetic appearance of end winding.

The technical scheme that the utility model adopted is as follows: this motor-spin-coil end fixture comprises the end winding that is exposed at the iron core outside, be strapped in the outer field no latitude band of described end winding and tie up the no latitude rope that described no latitude takes up the beginning position, its technical essential is: described no latitude band periphery is provided with protective ring, and described protective ring is fixedly connected by the support ring on the described iron core.

Advantage and the good effect that the utlity model has are: because the utility model is improved on the basis of the fixed structure that has motor-spin-coil now, only the end winding that is exposed at the iron core outside at rotor coil is set up fixture and is protected, promptly protective ring is set in no latitude band periphery, and it is fixedly connected by the support ring on the iron core, so itself and the immobile phase ratio of existing coil, simple in structure, easy to manufacture.It overcome that prior art exists when bondage does not have the latitude band, the gap phenomenon that may occur easily makes motor break down, influence the defective of the normal operation of motor.In addition, protect, so significantly strengthen the bulk strength of rotor coil end because of having set up fixture at end winding.This not only makes motor can be avoided the end winding torsional deformation effectively at frequent starting and when running up, guarantee that motor normally moves, and no longer be subjected to the influence of coil manufacturing and inserting-coil process, bondage does not have the latitude band the gap phenomenon can not occur again yet, has therefore also increased the aesthetic appearance of rotor coil end.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a kind of structural representation of the present utility model.

Sequence number explanation among the figure: 1 iron core, 2 end windings, 3 no latitude bands, 4 no latitude ropes, 5 retaining rings, 6 support rings.

Embodiment

Below in conjunction with Fig. 1 concrete structure of the present utility model is described further.This motor-spin-coil end fixture is improved on the basis of the fixed structure of existing motor-spin-coil, it comprises the end winding 2 that is exposed at iron core 1 outside, be strapped in end winding 2 outer field no latitude bands 3, and the no latitude rope 4 of tying up no latitude band 3 original positions, parts such as protective ring 5 and support ring 6.Wherein protective ring 5 and support ring 6 are the fixtures of setting up at end winding 2, and protective ring 5 can adopt shape, make as corrosion resistant plate etc., and it is arranged on no latitude band 3 peripheries.Support ring 6 is fixed on the iron core 1, and by the support ring 6 fixedly connected protective rings 5 on the iron core 1.Because the protective action of protective ring 5 and support ring 6 makes the bulk strength of rotor coil end 2 increase.This not only makes motor can be avoided end winding 2 torsional deformations effectively at frequent starting and when running up, and guarantees that motor normally moves, and no longer is subjected to the influence of coil manufacturing and inserting-coil process, when bondage does not have latitude band 3, also can not occur the gap phenomenon again.Therefore, also increased the aesthetic appearance of rotor coil end 3.

Claims

1. motor-spin-coil end fixture, comprise the end winding that is exposed at the iron core outside, be strapped in the outer field no latitude band of described end winding and tie up the no latitude rope that described no latitude takes up the beginning position, it is characterized in that: described no latitude band periphery is provided with protective ring, and described protective ring is fixedly connected by the support ring on the described iron core.
