Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a positioning and fixing device for asynchronous motor windings. Background Technology

[0002] As a core driving device in industrial production and household appliances, the stability of the windings of asynchronous motors directly affects the motor's operating efficiency, service life, and safety. During the manufacturing, assembly, and long-term operation of motors, windings may experience displacement, loosening, or even insulation damage. Traditional positioning and fixing methods suffer from insufficient precision, cumbersome installation, and poor adaptability, making it difficult to meet the high precision, strong stability, and standardized assembly requirements of high-efficiency motors for winding positioning. Therefore, there is an urgent need for dedicated positioning and fixing devices to optimize the winding installation process and improve structural reliability.

[0003] Asynchronous motors are widely used in many fields due to their simple structure, low cost, and stable operation. Traditional asynchronous motor winding positioning and fixing techniques, such as using steel end clamps and polyester fiberglass rope binding, can meet the structural requirements of small and medium-sized motors well, with relatively low cost and mature installation technology. However, when facing high-voltage, large, two-pole, high-power three-phase asynchronous motors, this technology reveals obvious shortcomings. The winding end coils extend a long distance from the iron core, and fixing them in this way alone results in insufficient structural stability. It is difficult to effectively resist the large vibrations and electromagnetic forces generated during motor operation, which can easily lead to winding deformation, insulation damage, and motor failure.
