It’s a riot of brass and steel, with a hand crank that drives the main winding shaft while powering a cam that guides the wire along the long axis of the coil form. Cams can be changed out for ...

lacking a ferrite core for testing, [Sandeep] used a plywood ring as a stand-in, but the results are satisfying enough to make any manual coil-winder envious.

Certain units deliver constant torque regardless of the slip speed so wire tension is constant even at high coil-winder speed. Adjustable brake units also accommodate different wire sizes ...

and outer axis winding verification. Only the inner axis acceleration torque will be described to illustrate the process. The mirror load inertia is known, but actuator coil inertia and ...
