Stepper-Controlled Coil-Winding Machine
Designed around the RSK2329 evaluation board, the Stepper-Controlled Coil-Winding Machine controls a stepper motor-based coil winder. The coil winder hardware is constructed out of 0.75" medium density fiberboard (MDF) board and commonly available 28TPI threaded rod. Using 7.2°-per-step unipolar stepper motors, the system can achieve a stepping precision of 0.0007" per step with impressively low backlash. The system can accommodate coils up to 12", making it a versatile solution for numerous applications. It works especially well for small quantity production of flyback transformers and special RF chokes, among other products.
