Abstract

PURPOSE:To facilitate the bending processing by forming a spacer part between the cylindrical part of a bobbin and a straight angle line, when bending the inner periphery side end part of the straight angle line wound on a bobbin in L shape as a terminal for connection and drawing out to the periphery of a coil. CONSTITUTION:A straight angle line 1a approximately 3mm in board thickness is wound plural times (three times in figure) on a bobbin made of resin so as to make a field coil 1. The bobbin 2 is composed of a rectangular tube part 2a for engaging with the periphery of a pole core 4 and a brim part 2b for supporting the straight angle line 1a. The periphery side end part of the coil 1 is twisted 90 deg. and made a terminal for connection, and the inner periphery side end part 1b is bent in L shape and drawn out to the periphery of the coil 1, and is made a terminal for connection. To fill the gap arising between the tube part 2a of the bobbin 2 and the second layer of the coil 1, a projection 9a l in thickness is provided in the tube part 2a at the winding start part of a coil 1, and a spacer part 9 is made. Hereby, the bending processing of the inner periphery side end part 1b can easily be done.
