Abstract
A method for high speed spin winding a coil on a continuous lamination core. A two piece or hinged bobbin having two flanges is placed around a leg of the transformer core and snapped together. Both flanges include an outwardly facing surface which defines a concentric groove. One flange includes passages for receiving printed circuit board terminating pins which are installed prior to winding the coil. The other flange has a circumferential gear located in its outwardly facing surface. The core with bobbin and terminating pins installed is placed into a spin winding fixture. A bobbin bearing having a bearing surface including a circumferential ridge is placed adjacent the outwardly facing surfaces of the two flanges such that the circumferential ridges are partially received within the concentric grooves of the outwardly facing surfaces of the two flanges. A wire feeder terminates the leading end of the coil wire on one of the terminating pins. A drive gear engages the circumferential gear on the flange and rotates the bobbin at high speed drawing wire from the wire feeder. The wire feeder moves back and forth between the two flanges to uniformly wind the coil wire on the bobbin. …
