US Patent 5310125: Transformer coil winding apparatus for winding…
US 5310125 · granted 1994-05-10
Abstract
A transformer coil winding apparatus for winding a winding wire on a coil bobbin comprises a rotating drive mechanism for rotatably driving the coil bobbin by a friction force between the coil bobbin and the rotating drive mechanism. Further, the transformer coil winding apparatus comprises a detection unit provided on said coil bobbin, a rotation number counting unit for counting number of rotations of the coil bobbin on the basis of the output of the detection unit, and a drive unit for rotatably driving the rotating drive mechanism in response to the number of rotations on the rotation number counting unit. Therefore, the production cost for the transformer can be lowered.
