Alternating current generator rotor

摘要

A rotor for an alternating current generator that includes a steel rotor core that carries a field coil supporting spool. The core has axially extending circumferentially spaced slots on its outer periphery that receive axially extending and circumferentially spaced ribs of the spool. The spool ribs are connected to spool end flanges. A field coil is wound on the spool and core. The inner turns of the field coil contact outer surfaces of the spool ribs and outer surfaces of the core located between the spool ribs.
