Embodiment Construction

[0024] The present invention will be further described below in conjunction with specific embodiments.

[0025] like figure 1 , 2 , 3, the first embodiment of the present invention is used for a volume of 0.4m 3 The coil winding is assembled and fixed, including the following steps:

[0026] (1) The casting plug 5 and the casting tube 4 are made. The casting plug 5 includes a first cylindrical portion 501, a second cylindrical portion 502 and a round cake portion 503 whose outer diameters increase in turn. The outer diameter of the first cylindrical portion 501 is connected to the coil The inner hole of the winding 2 is matched, the outer diameter of the second cylindrical portion 502 is matched with the inner hole of the end of the frame 1, and the length is 5mm smaller than the distance from the end face of the frame 1 to the same end face of the coil winding 2. The pouring tube 4 includes a coaxial first. A pipe portion 401, a second pipe portion 402, the outer diameter ...

Abstract

The invention discloses a coil winding end fixing method, which is characterized by comprising the steps of (1) manufacturing a pouring plug and a pouring pipe; (2) mounting a coil winding in a machine base; (3) coating the outer circle surface of the pouring plug and the inner circle surface of the pouring pipe with a release agent; (4) mounting the pouring plug and the pouring pipe; (5) weighinga proper amount of insulating sealant, and putting the insulating sealant into a drying room for heating until the insulating sealant is liquefied; (6) pouring the insulating sealant to the coil winding; and (7) solidifying the machine base and the coil winding into a whole, and disassembling the pouring plug and the pouring pipe. The beneficial effects of the invention are that the insulating sealant is adopted to fill each gap in the workpiece and covers the two end surfaces of the coil winding, the coil winding, the insulating sealant and the machine base are solidified into a whole, the turn-to-turn insulation between the coil windings and the ground insulation between the coil winding and a conductor are enhanced, the strength of the workpiece is enhanced, and the vibration and noiseduring the operation of the motor are reduced; dust, water and oil are effectively prevented from entering the coil winding, and various new requirements of the motor are met.

Description

technical field [0001] The invention relates to the technical field of electric motors, and in particular, to a method for fixing the ends of coil windings. Background technique [0002] With the development of the motor industry, users have new requirements for motors: 1) It is required that the ends of the coil windings cannot enter water, oil, dust and other impurities; 2) The motor is required to vibrate less during operation. However, the existing coil winding dipping process cannot meet the above requirements. There are gaps between the coil winding and the frame and between the coil windings. Dust, water and oil are easy to enter, and great vibration and noise will be generated during operation. SUMMARY OF THE INVENTION [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a method for fixing the ends of coil windings. The method adopts the method of pouring insulating sealant on the coil winding, so that the insula...
