Abstract

The utility model relates to a binding structure of the end of a rotor coil of a big-and-middle-sized wound rotor electric motor, which comprises a polyester-glass fabric marginal tape, and is characterized in that the binding structure further comprises polyester-glass fabric, glass fiber binding yarn and a weft-free tape, wherein the polyester-glass fabric is arranged above the rotor coil, the weft-free tape is arranged above the polyester-glass fabric, and the weft-free tape is bound close to the glass fiber binding yarn. The polyester-glass fabric is a sheet of the polyester-glass fabric of the thickness of 1mm, and the glass fiber binding yarn is the glass fiber binding yarn of 5 phi-16phi. The polyester-glass fabric is characterized in that the width is equal to the axial binding width of the end of the weft-free tape, and the length is that of the external circumference of the end of the rotor coil. The diameter of the glass fiber binding yarn is equal to the binding thickness of the weft-free tape, and the length is that of the external circumference of the end of the rotor coil. The structure has beneficial effects that: firstly, after using the binding structure, the binding quality of the end of the rotor coil is improved, secondly, accidents caused by the releasing of the weft-free tape during the operating process of the electric motor are reduced. Tests show that the binding structure is convenient to operate, and is practical and effective.

Description

Large and middle size motor rotor coil end banding structure

Technical field

The utility model relates to the binding structure of a kind of big-and-middle-sized wound rotor motor rotor coil end, belongs to technical field of motors.

Background technology

Motor is after the moulding of rotor coil end, welding, need its end cylindrical is carried out the hoop-driving colligation with no latitude band, in case principal vertical line circle end is subjected to the outside whipping of action of centrifugal force when motor moves, cause the sealing-off of rotor coil and head place or rotor leading-out wire, cause electrical fault.

In the colligation of motor after the moulding of rotor coil end, welding in the past, all be with no latitude band in the certain width scope of end around on tens circles, when coiling, because of do not have locating, slide between the upper and lower layer of no latitude band and misplace, cause no latitude tape thickness inequality after the colligation, end face is irregular, is easy to occur local size and exceeds the rotor core cylindrical, cause rotor assembling difficulty, the colligation of need doing over again does not have the phenomenon of latitude band, and the colligation of whole end is not attractive in appearance yet, influences presentation quality.

Summary of the invention

The purpose of this utility model is to propose the binding structure of a kind of big-and-middle-sized wound rotor motor rotor coil end, accomplishes thickness uniformity after the colligation, and end face is neat.

For achieving the above object, the technical solution of the utility model is: described binding structure comprises jewel cloth 1, glass fiber binding yarn 2, rotor core 3, rotor coil 4, no latitude band 5 and jewel cloth marginal belt 6; The top of rotor coil 4 is a jewel cloth 1, and the top of jewel cloth 1 is no latitude band 5, and no latitude band 5 has been tied up near glass fiber binding yarn 2.

When banded end does not have latitude band 5, increase a jewel cloth marginal belt 6, the manufacture method of this marginal belt 6 is: with the jewel cloth 1 that 1mm is thick, width approximates the axial colligation width of no latitude band in the end, length is rotor coil end outer circumference, uses the glass fiber binding yarn 2 of ￠ a 5～￠ 16 again, and the diameter of rope can be equivalent to not have the colligation thickness of latitude band, length is rotor coil end outer circumference, on one side glass fiber binding yarn 2 is wrapped with the length direction of jewel cloth 1 and is sewed it up; When banded end does not have the latitude band, earlier jewel cloth marginal belt 6 is placed, there is an end of glass fiber binding yarn 2 to be placed on the coil outer end, no latitude band 5 has been tied up near glass fiber binding yarn 2, push down jewel cloth 1, do not have the location that latitude has had glass fiber binding yarn 2 like this, just can landing, just can accomplish that thickness is even, the end face neat appearance.

The beneficial effects of the utility model:

1, use this binding structure after, improved the colligation quality of rotor coil end;

2, reduced in the motor operation course because the fault that no latitude band gets loose and causes.

This binding structure of empirical tests is easy to operate, practicability and effectiveness.
