This article explores the important winding factors during motor repair, emphasizing the importance of maintaining the number of turns, wire diameter, and arrangement of the coils. Meticulous repair work ensures your motor's performance and reliability.

Electric motors play an important role in various industrial applications, however, during maintenance and repair, special attention needs to be paid to the windings of the motor. Below we will explore several key winding factors in motor repair that have a profound impact on motor performance and reliability.

The number of coil turns in an electric motor is one of the core elements of its design. When disassembling and repairing, be sure to record the number of turns of the original enameled wire. Changes in the number of turns can cause a series of problems. Increasing the number of turns may lead to a waste of copper wires, making it difficult to manufacture embedded wires, and also increases leakage reactance, resulting in a reduction in the maximum torque and starting torque of the motor. Conversely, reducing the number of turns may result in an increase in the motor's no-load current and a decrease in power factor. What's more serious is that if the number of turns of the three-phase windings is unequal, it will cause the three-phase current to be unbalanced, thereby reducing the performance of the motor.

The diameter of the enameled wire conductor must meet the design requirements. If the wire is too thin, or is subjected to excessive pulling force when winding, the winding resistance will increase, which will directly affect the performance of the motor. On the contrary, if the wire is too thick, it will become difficult to insert the wire, which not only wastes material, but may also cause problems with the compactness of the winding.

When winding the coil, make sure the wires are arranged neatly to avoid confusion. The chaotic cross arrangement will increase the volume occupied by the wires in the slot, making it difficult to insert the wires, and may also easily lead to inter-turn short circuits between coils. This can cause motor failure and reduced performance.

When winding, the insulation of the wire must not be allowed to be damaged at all. Broken insulation can cause a turn-to-turn short between coils, an extremely dangerous situation that can cause electrical failure or fire.

Great care must be taken during repairs on electric motors, especially during winding maintenance and rebuilding. The selection of turns, wire diameter and arrangement is critical to the performance and reliability of the motor. Maintaining the health of your motor is key to ensuring its long-term stable operation. Therefore, careful repair work and following design requirements are integral to maintaining motor performance. Proper repair and maintenance of electric motors ensures reliable service in a variety of applications and reduces the risk of unnecessary breakdowns.
