4 Primary Aspects to Consider When Selecting a Coil Winding Machine

The right coil winding machine can be selected if requisite time is spent considering the final operational requirements. The buyer should know exactly what he is expecting from the coil winding machine in terms of the final output, compatibility with other machines, application environment, etc.

How to Choose a Coil Winding Machine

When picking out a coil winding machine, you can take into consideration the physical design of the coil, production rate, etc. However, the first two things to consider are the wire diameter and coil dimension. These two factors are explained in detail below:

    • Weight of Coil

The coil dimensions along with the total weight of the coil need to be considered when choosing a machine. The overall functioning of the machine will change if the coil weighs more or less. This will have a direct impact on your deliverables. Additionally, a machine that is unable to handle the requisite weight of the coil will hamper the overall production process. Hence, the weight of the coil needs to be taken into consideration when deciding on the specifics of the machinery.

    • Wire Diameter

Wires with varying diameters will be wound using the coil winding machine. The minimum and maximum diameter of wires that will be wound on the machine should be taken into consideration. This will allow you to narrow down the choices considerably.

    • Coil Dimension

A coil winding machine can easily accommodate a wire with small dimensions. Wires with large dimensions need to be used with machines designed specifically for that purpose. Hence, the largest coil dimension you require should be taken into consideration when purchasing a coil winding machine. The dimensions of round/ square/ rectangular/ trapezoidal coils can be calculated taking into consideration the length of the coil, as well as the diameter (of round coils) and diagonal length (of square/ round/ trapezoidal coils).

    • Coil Winding Method

The methods employed to wind the coils need to be taken into consideration when choosing the right machine. Will the coil be wound at slow speeds with high torque, or high speeds with low torque? Along with this, the rate of production needs to be considered to ensure that the right combination of speed and torque matches with the weight and dimensions of the coil.

Traverse Unit: Interrelationship between Wire Diameter & Coil Dimension

Traverse speed and length of a machine help in determining the output. These factors are dependent on the wire diameter and coil dimension. The torque is also dependent on these two factors. Hence, a lot of importance is paid to these factors during the machine selection stage.

When the wire diameter is large, the traverse unit is higher, and vice versa. When the traverse unit is higher, time taken to complete one turn is longer. The traverse unit and speed need to be in sync to ensure proper layer winding. If the two are not coordinated, the turns will overlap, and machine performance will be negatively affected.

With this information, we understand that the winding speed is dependent on the wire dimensions as well as the length. The traverse unit is dependent on the winding speed. Thus, the wire diameter and coil dimension should be the primary factors taken into consideration when purchasing coil winding machines.
