With the continuous advancement of the process technology of the motor manufacturing industry and the popularization and application of automated production lines, coil manufacturing equipment such as high-speed mechanical winding devices, automatic winding devices, and CNC up-type machines are becoming more and more widely used in the manufacture of motor coils. In order to ensure dimensional stability during coil forming, higher requirements are placed on the softness of the wrapped copper flat wire, that is, the copper wire is required to have high elongation, low rigidity, small rebound angle, and ensure winding. The copper-clad flat wire has the above-mentioned performance dispersion.
In general, the softness of the wrapped copper wire is mainly affected by factors such as copper material, annealing temperature, and package sintering. In this paper, the effects of copper material, annealing temperature, and packaged sintering on the softness of Copper Winding Wire are studied. Polyester imide/polyamide composite enameled wire, heat grade 180 This product has good thermal shock resistance, high softening breakdown temperature, excellent mechanical strength, good solvent resistance and refrigerant resistance, and the weakness is easy under the premise of blocking. Hydrolysis, widely used in motors, electrical appliances, instruments, power tools, dry power transformers and other windings with high heat resistance requirements.
Polyesterimide/polyamide-imide composite enamelled wire is widely used in domestic and overseas heat-resistant enameled wire, its thermal grade is 200, the product has high heat resistance, and also has anti-freezing agent, cold resistance, radiation resistance, etc. Characteristics, high mechanical strength, electrical function is not chaotic, chemical resistance and refrigerant resistance are good, and overload capacity is strong. Widely used in refrigerator compressors, air conditioning compressors, power tools, explosion-proof electric ideas and high temperature, high cold, radiation, overload and other conditions used in the motor, electrical appliances.
