Easy machine rapidly winds coils

Coils are integral to an enormous array {of electrical} parts and circuits. Transformers, electromagnets, antennas, motors, inductive heaters, and a lot extra all depend on coils. And plenty of of these want hundreds of wraps to work as supposed. That may be an enormous quantity of labor to finish by hand and the outcomes could be sloppy anyway, so Pisces Printing designed this coil winder machine.

That is precisely what it says on the tin: a machine that winds coils so that you don’t need to. The consumer can enter the variety of wraps and the size of the coil, then the machine will deal with the remaining. And the machine makes use of a lathe-style chuck to carry the core, so it might probably accommodate a variety of sizes and supplies. All of the mechanical elements are both 3D-printable or accessible off-the-shelf, like fasteners and aluminum extrusion.

The machine works utilizing a pair of stepper motors. One rotates the chuck to wind the coil and the opposite drives a lead screw that pulls the information parallel alongside the axis of the core, making certain a clear and uniform wrap. An Arduino Nano board controls the stepper motors by way of a customized PCB populated with drivers. It additionally shows the straightforward consumer interface on a 16×2 character LCD, with a number of tactile buttons for inputting coil parameters.

If you could wind coils with any type of regularity, then you’ll be able to take inspiration from this design to construct your personal time-saving machine.
