Abstract
The invention discloses a method for binding an end coil of a motor stator, which relates to a motor end coil binding method, in particular to the fixing and binding of the end coil of a high-power alternating current motor. The method involves an outer coil, an inner coil, end hoops and a binding point. A certain number of end hoops are installed between the outer and the inner coils, and the outer coil, the inner coil and the end hoops are bound into a whole body in the position of the binding point. The method enhances the capability of a stator coil end in resisting insulation damage caused by electromagnetic vibration, remarkably improves the heavy load operation capability of the motor and prolongs the service life.
Description
Technical field:
A kind of method for binding end coil of motor stator is a motor end coil banding method, particularly fixedly colligation of high-power AC motor end coil.
Background technology:
At present motor end coil banding method all adopt with the ectonexine of double-layer coil respectively colligation together, what have adds the colligation of end hoop and forms " parallelogram " binding structure in that coil is outer; During machine operation, coil temperature increases, the relative deliquescing of insulating material, because the electromagnetic force that alternating current produced is a physical quantity that constantly changes on size, direction, the amplitude of the electromagnetism concussion that it produced also changes along with increasing, and causes coil and coil interlayer to produce friction, also produce friction between the electromagnetic wire of coil inside, thereby the insulation of end winding is at first damaged, cause short circuit, damage motor windings; The electromagnetic wire vibration causes motor to damage directly influence safety in production.
Summary of the invention:
A kind of method for binding end coil of motor stator goal of the invention of the present invention is: seek a kind of colligation position that changes end winding end hoop of design, overcome a kind of stator end coil banding method of coil interlayer friction.
A kind of method for binding end coil of motor stator of the present invention is achieved in that by outer coil, inner coil, end hoop, bundle node to be formed; Outer coil and inner coil are integral in the colligation of bundle node, and some ends hoop perhaps is installed between outer coil and inner coil, at the bundle node outer coil, inner coil and the colligation of end hoop are integral.
This method can make winding overhang form a plurality of interconnective little " triangle ", and end coil stability is improved, control vibration friction.
The beneficial effect of a kind of method for binding end coil of motor stator of the present invention: strengthen the ability that the anti-electric and magnetic oscillation of stator coil end damages insulation, motor heavy service ability significantly improves, and prolong useful life.
Description of drawings:
Accompanying drawing 1 is a kind of method for binding end coil of motor stator schematic diagram of the present invention
Among the figure: outer coil (1), inner coil (2), end hoop (3), bundle node (4)
Embodiment:
A kind of method for binding end coil of motor stator of the present invention is by being made up of outer coil (1), inner coil (2), end hoop (3), bundle node (4); Outer coil (1) and inner coil (2) are integral in the colligation of bundle node (4), some end hoops (3) perhaps are installed between outer coil (1) and inner coil (2), outer coil (1), inner coil (2) and (3) colligation of end hoop are integral at bundle node (4); End hoop (3) is made continuous by insulating material or is had certain intervals and thickness bar circle.
Claims (2)
1, a kind of method for binding end coil of motor stator is characterized in that: be made up of outer coil (1), inner coil (2), end hoop (3), bundle node (4); Outer coil (1) and inner coil (2) are integral in the colligation of bundle node (4), some end hoops (3) perhaps are installed between outer coil (1) and inner coil (2), outer coil (1), inner coil (2) and (3) colligation of end hoop are integral at bundle node (4).
2, according to the described a kind of method for binding end coil of motor stator of claim 1, it is characterized in that: end hoop (3) is made continuous by insulating material or is had certain intervals and thickness bar circle.
