Pickup coils are integral components in various applications, most notably in electric guitars. These coils convert different forms of energy into electrical energy. The fundamental elements of a pickup coil include magnets, a bobbin, and copper wire. The magnets, usually an alloy, are centrally positioned in the bobbin, with the wire wrapped around them. The design of pickup coils typically involves a high number of fine wire turns, generally of 42 or 43 gauge. Given the fine nature of the wire and the high turn count—ranging from 6,000 to 12,000—special care is necessary during the winding process.

When winding fine wire on a rectangular bobbin, tension management becomes crucial. As the wire wraps around the bobbin, tension varies, with the wire being pulled more intensively at two points and relieved at two others. This uneven tension can lead to issues such as wire breakage or elongation, especially with the high-speed winding required for large turn counts. Therefore, using a high-speed, automatic, and programmable winding machine equipped with a graduated tensioner unit is essential for producing high-quality pickup coils.

The ideal winding machine for pickup coils must feature high-speed capabilities, along with programmable settings to control various parameters. Key features of such machines include:

• High-Speed Winding: Essential for handling the large number of turns efficiently.

• Graduated Tensioner Unit: Allows for precise tension adjustments, ensuring uniform winding and preventing wire breakage.

• Soft Start and Soft Stop: Gradual acceleration and deceleration prevent sudden stress on the wire, reducing the risk of breaking or elongating the fine wire.

Programmable winding machines, like those offered by Acme Mechatronics, Inc., provide numerous advantages:

• Precision Control: The ability to program parameters such as wire gauge, winding width, starting point of the turns, speed, and tension ensures consistency and quality in the winding process.

• Efficiency: High-speed winding combined with programmable settings allows for efficient production, crucial for high turn counts.

• Quality Assurance: Features like soft start and soft stop, along with fine tension adjustments, enhance the quality of the wound coils by minimizing defects and maintaining the integrity of the wire.

Acme Mechatronics, Inc. offers models like the AEX-01 and AEX-02, equipped with graduated tensioner units specifically designed for winding guitar pickup coils. These machines can program various parameters, ensuring optimal winding conditions for producing high-quality coils. The following image shows two coils wound for guitar pickups, illustrating the precision and capability of these machines.

During the winding process, the pressure of the wound turns can cause the bobbin flange to expand, potentially compromising the functionality of the pickup coil. To prevent this, an accessory known as a tailstock is used. The tailstock provides support from the opposite side of the bobbin, ensuring the flanges remain stable and intact. Additionally, the tailstock facilitates quicker loading and unloading of the bobbin, enhancing overall efficiency.
