Full-film structure electromagnetic wire thin-film adhesion detection method

Abstract

The invention discloses a full-film structure electromagnetic wire thin-film adhesion detection method for a motor coil. The full-film structure electromagnetic wire thin-film adhesion detection method is divided into two parts: a twisting test and a soaking test, which are performed in turn. The full-film structure electromagnetic wire thin-film adhesion of the motor coil is judged through the twisting test and soaking test. The twisting test comprises the following steps: intercepting two sections of a finished product electromagnetic wire with the length between 100 and 200mm; clamping and fixing one end of the electromagnetic wire respectively, and twisting 360 degrees for five times after clamping the other end of the electromagnetic wire; and clockwise twisting a test piece, anticlockwise twisting another test piece, and observing whether the electromagnetic wire thin-film is in glue failure. The soaking test comprises the following steps: soaking the twisted part in water for about 4 to 10 minutes; and using 1,000V insulated resistance tester to measure that the insulated resistance between a copper conductor and external insulation is not less than 10 megohms. The full-film structure electromagnetic wire thin-film adhesion detection method has the characteristics that: the electromagnetic wire thin-film adhesion detection method is performed through the twisting test and soaking test respectively, so the requirement on the detection condition of the detection is reduced.

Description

technical field [0001] The invention relates to a method for detecting the performance of motor components, in particular to a method for detecting the film adhesion of a full-film structure electromagnetic wire of a motor coil. The detection method achieves a reasonable evaluation of insulation adhesion through tests that are more suitable for the use of electromagnetic wires. sexual purpose. Background technique [0002] The traction motor is generally composed of two parts, the stator and the rotor, and the stator is mostly wound by electromagnetic coils. In order to ensure the performance of the stator, the current stator is generally wound by a full-film structure electromagnetic wire. When the film structure electromagnetic wire is wound and formed, the insulating film of the electromagnetic wire is prone to deglue, so it is necessary to test the insulation adhesion performance of the film. The traditional insulation adhesion performance test is to evaluate the film ad...
