Easy machine rapidly winds coils

Coils are integral to an unlimited array {of electrical} parts and circuits. Transformers, electromagnets, antennas, motors, inductive heaters, and a lot extra all depend on coils. And lots of of these want hundreds of wraps to work as meant. That will be a large quantity of labor to finish by hand and the outcomes can 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 must. The consumer can enter the variety of wraps and the size of the coil, then the machine will maintain the remainder. And the machine makes use of a lathe-style chuck to carry the core, so it may well accommodate a variety of sizes and supplies. All of the mechanical components 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 means of a customized PCB populated with drivers. It additionally shows the straightforward consumer interface on a 16×2 character LCD, with just a few tactile buttons for inputting coil parameters.

If it’s essential wind coils with any sort of regularity, then you possibly can take inspiration from this design to construct your individual time-saving machine.
