Abstract
An AC dynamo electric machine for a motor vehicle includes an AC dynamo machine bodycomposed of a rotorconstituted by a first rotatable shaftsupported rotatably by a pair of bearings, a rotor corefixedly secured to the first rotatable shaftand a field windingwound on the rotor core, a statorcomposed of a stator coredisposed in opposition to the rotorand a polyphase stator windingwound on the stator coreand a bracketsupporting the pair of bearingsand the stator, and a rotational position detector for the control purpose composed of a second rotatable shaftcoupled to the first rotatable shaftthrough a large magnetic reluctance portion, a second rotorfixedly secured to the second rotatable shaftand a second stator windingfor generating an output voltage based on rotation of the second rotor
