This video shows a custom inductor being wound on an automated winding machine. The wire is wound on a coil form or bobbin. After the machine is programmed for the coil being wound, the bobbin is secured to a winding arbor on the machine. The wire is then secured to the bobbin and the machine winds the number of turns specified. The finish wire is then secured to the coil and the part is ready for assembly.
