End fixing method for motor stator winding

Abstract

Disclosed is a fixation method for a motor stator winding overhang, which affixes a reel of double sided tape to an external circumference of the motor winding overhang; a reel of fiber felt is affixed to the double sided tape; a non-woven fiber tape is wound round the fiber felt; a TCP tape is wound round the non-woven fiber tape; the TCP tape is heated and naturally cooled, then naturally shrinks and fixes the fiber felt and the non-woven fiber tape wrapped in the TCP tape on the motor winding overhang to realize motor stator winding overhang fixing. The method adopts the simple technical proposal, has the fixed bundling of the motor stator winding overhang and good structure stability, can effectively improve the safety of motor operation, be applied to industrial production, and act as the fixation method for a small diameter motor stator winding overhang.

Description

technical field [0001] The invention discloses a method for fixing the end of the stator winding of a motor, which is particularly suitable for fixing the end of the stator winding of a small and medium-sized motor. Background technique [0002] In order to ensure the normal operation of the motor and reduce or avoid coil loosening during operation, the part of the motor stator winding coil extending from the core slot needs to be fixed to ensure that the winding end of the motor will not be loose and deformed during operation; traditional In the production process, a rigid end ferrule is usually placed outside the winding end, and then an insulating glass ribbon is inserted between each winding end and the rigid end ferrule to realize binding and fixing. For motors with larger stator diameters, due to the relative The gap between adjacent windings is relatively large. When insulating glass ribbons are used to interpenetrate and bind, the process is simple, the labor intensi...

AI Technical Summary

Problems solved by technology

When the diameter of the motor stator is small, due to the small gap between adjacent windings, it is not easy to insert and fix with glass ribbons, and some coils are not tied tightly due to negligence in production, and the fixation is not in place, resulting in motor failure. During the operation process, the winding end will loosen and vibrate. In severe cases, the adjacent coils at the winding end will collide and rub against each other to destroy the insulation layer on the surface of the coil, causing a short circuit of the motor and bringing great hidden dangers to the safe operation of the motor.
