When the fully automatic stator winding machine is in operation, it has specific considerations for the material and wire diameter of the enameled wire. These considerations usually revolve around factors such as the performance specifications of the motor, the technical capabilities of the winding machine, and the overall production efficiency. The following is Vacuz’s in-depth discussion of the enameled wire selection requirements and suggestions on how to make a wise choice:

1. Material considerations of enameled wire

Fully automatic stator winding machines generally tend to use enameled copper wire, not only because of its excellent conductivity, but also because of its excellent corrosion resistance. Enameled copper wire is based on polyurethane or polyamide and coated with a special insulating varnish, which gives it good insulation, high temperature resistance and wear resistance, which are essential for motor stator windings. Of course, in specific situations, such as weight restrictions or situations where higher mechanical strength is required, aluminum wire or iron wire will also be considered. But it is worth noting that the conductivity of aluminum wire is slightly inferior, while iron wire is suitable for some special application scenarios due to its excellent hardness and strength.

2. Wire diameter selection of enameled wire

The wire diameter size of the enameled wire has a direct impact on the performance and production efficiency of the motor. Wire diameter is usually measured in millimeters (mm).

Thicker wire diameter: This type of enameled wire is more suitable for high temperature and high load environments, such as high-power motors. They have excellent high temperature resistance and can withstand greater power. At the same time, they have low resistance and conduction current, which helps reduce energy loss and improve motor efficiency. However, thick wire diameter enameled wire may place higher requirements on equipment during the winding process, increase the difficulty and precision challenges of winding, and may be more cumbersome when replacing single strands of wire.

Thinner wire diameter: This type of enameled wire is more suitable for occasions that require fine coils, such as small or micro motors. Thin wire diameter enameled wire can produce more turns, thereby improving the output efficiency and operating speed of the motor. However, their high temperature resistance is relatively weak and the applicable temperature range is limited.

3. Wise selection strategy

When choosing enameled wire, the following factors should not be ignored:

(1) Motor performance requirements: According to the motor’s power, efficiency, temperature resistance and other performance requirements, select the appropriate enameled wire diameter and material.

(2) Winding machine configuration: Select the appropriate enameled wire diameter according to the technical specifications and production capacity of the winding machine. The thicker the wire diameter, the higher the requirements for the equipment, and the difficulty and precision of winding will also increase accordingly.

(3) Production efficiency: The choice of wire diameter also affects production efficiency. For example, enameled wire with a fine wire diameter has more turns and may require a higher winding speed, while enameled wire with a thick wire diameter may require a relatively low winding speed.

(4) Cost control: The cost of enameled wires of different specifications varies. Under the premise of meeting performance requirements, cost factors should be reasonably considered.

In summary, the fully automatic stator winding machine has specific requirements for the material and wire diameter of the enameled wire. When selecting, multiple factors such as motor performance requirements, winding machine configuration, production efficiency and cost should be considered comprehensively to ensure that the appropriate enameled wire is selected.
