ABSTRACT:
A non-magnetic molded plastic bobbin has a bore by which the bobbin is slip-fitted upon the cylindrical outer surface of the inner body carried by the rotating shaft. An integrally molded radial thrust flange at one end of the bobbin slip-fits against a radial flange of the inner body and defines an annular recess for the winding of a coil on the bobbin. The molded plastic bobbin also has an annular recess which extends concentric with the bore to receive the magnet body therewithin. A ridge is molded integrally with the bobbin on the wall thereof defining the magnet body annular recess and engages against the magnet body to retain the magnet body within the recess. A plurality of snap fingers are molded integrally with the bobbin and project inwardly from the bore thereof into slip-fitting relationship within an annular groove in the inner body to enable rotation of the inner body relative the stationary bobbin while retaining the bobbin axially relative the inner body. An integral axial extension of the bobbin abuts with a stationary clutch housing to retain the stationary field rotationally stationary during rotation of the inner body.
