How do you ensure consistency in your winding process? In our experience, the most often overlooked detail of coil winding is proper and uniform tensioning. Uniform tension is critical to the production of high-quality products. Every manufacturer of magnet wire publishes a chart of recommended wire tensioning equipment, by wire size, for its products. Typically, you will use a value equal to 50 – 80% of the maximum recommended tension to ensure that the magnet wire is not elongated during the winding process (which would decrease the diameter of the wire and increase its resistance), and possibly damage the wire insulation due to stretch.

A tension meter is used to measure winding tension on the magnet wire. The ideal spot to measure tension is between the final wire guide device (pulley or wire tube) and the coil since this gives the true tension on the magnet wire. Tensioners can be mechanical, with either direct reading for round coils, or dampened for square or rectangular coils, or electronic, which can be programmed for sampling rate. Another often-overlooked element of tensioning is whether your tensioner compensates the applied tension during the wire build of your coil.

As your coil builds in size, you will be pulling more wire length per second of winding. If your tensioner does not compensate for this, your tension will increase as your coil builds. To ensure uniformity and consistency, make sure that your tensioners, either mechanical or electronic, are of the compensating type. We feature tensioning equipment manufactured by ALTIC and SYNTHESIS.
