FIXED FIELD INDUCTOR-TYPE GENERATOR AND METHOD OF PRODUCING THE SAME

摘要

In a fixed field inductor-type generator having an annular stator core on which an armature coil is wound and a field coil which is disposed stationary in said stator core, the field coil is located in space defined by a pair of rotatable pawl-like magnetic poles that are opposed to each other and are supported by a rotary shaft. The field coil is held by a holding member made of a nonmagnetic metal, and is secured to the stator core. The field coil-holding member has fixed collars, which fastened to the inner peripheral surface of the stator core via a plastically deformable metallic coupling member. The field coil is wound on a curved spring steel plate and receives the expanding force at all times from the inner peripheral side thereof. The field coil is contained in the field coil-holding member and is firmly supported by an adhesive that is charged thereinto.
