AC motors are the most widely used motors in the winding machine and in the automatic thread winding machine
industry. The life of the AC motor of the winding machine is relatively long in actual operation, and it is generally not easy to be damaged. However, the absolute number of AC motors in actual use is large, so it is often found that the number of damage to the AC motor of the winding machine is still large. This is also why most of the motor repairs are repairs to the AC motor.
The maintenance technology of AC motor windings is mainly based on understanding and mastering the basic working principle, and learning to analyze the development of various AC motor windings. As long as you understand and master the drawing of the winding diagram of the winding machine, and then obtain some parameters about the motor winding development drawing through the original (old) motor or manual, and draw out the winding expansion diagram, in actual operation, according to the drawing, AC motor winding repair techniques are also not very difficult.
The type of automatic thread winding machine windings of AC motors is complex and diverse, but the working principle is basically the same. The main function of the stator winding is to generate a rotating magnetic field. The electric energy absorbed from the power source is transmitted to the rotor through the rotating magnetic field, so as to drag the mechanical load Is to work, that is, to complete the work of converting electrical energy into mechanical energy. Therefore, in an AC motor, the stator is called an armature and the stator winding is called an armature winding. Most of the rotor windings are cage rotor bars, which generally do not present a major problem. The other part is winding, and the winding arrangement of the winding machine is basically the same as that of the stator. Therefore, in the maintenance technology of the winding motor AC motor winding, it is necessary to grasp the main line of the rotating magnetic field generated by the winding.
