- The difference between the motor lead wire and the ordinary wire and cable is that the lead wire is permanently connected to the main wire of the motor winding, and is affected by mechanical vibration and other various environments along with the motor body and equipment. Moreover, in the manufacturing process of the motor, due to the winding processing technology of different motor manufacturers and the relationship between the lead wires of different series of products and related components, the actual operating conditions of the motor lead wires are more uncertain.
The most important technical problem of the motor lead wire is the cracking of the insulating sheath after the process treatment. Therefore, the type test items of the finished wire include the withstand voltage test items after bending, thermal effect treatment, solvent treatment and dipping treatment. It is the key quality index of the motor lead wire. Freon-resistant cords are mainly used for refrigerators and compressor motors. They need to pass the corresponding requirements of refrigerant resistance, solvent resistance, environmental stress crack resistance, flexibility, heating shrinkage, thermal stability, thermal aging, insulation to conductor clips Tightness and other tests to ensure long-term reliable operation of refrigeration equipment.
When selecting the motor lead wire, on the one hand, it is to determine the electrical performance parameters according to the rated current and voltage level of the motor. In order to standardize the manufacturing and inspection control of motor lead wires, JB6213.1-5 is a relatively comprehensive technical standard, and it is also a technical document for motor manufacturers to select and accept materials. The motor lead wires are classified according to the three operating temperatures of 70 degrees, 90 degrees and 125 degrees. Therefore, when selecting the motor lead wires, the selection should be made according to the actual operating temperature of the motor and the specific environment, and the actual operating state should be checked. Necessary tracking verification.
The degree of combination between the insulation sheath of the motor lead wire and the wire core is directly related to the final electrical performance compliance and wiring operation, and is directly related to the processing technology of the motor winding, which is also a quality control link that motor manufacturers pay more attention to.
The selection of motor winding lead wires is related to the voltage level, temperature resistance level, dipping process, and working environment of the motor. In fact, the long-term working temperature specified in the wire and cable standards is not completely consistent with the temperature resistance level of the motor. In general, the operating temperature of the lead wire is lower than the winding temperature, so it should be considered when designing the motor. When installing the wire, pay attention to the bending radius of the wire should not be less than 4 times the outer diameter of the wire, otherwise the insulation layer of the wire may be cracked.
