A rotating electric machine including: a bracket holding a rotor and a stator of a motor; a heat sink provided fixedly to the bracket on an outside of the bracket; a resolver disposed between the heat sink and the motor; a stator circuit portion and a field circuit portion disposed to the heat sink on a side opposite to the resolver; and a control board supported on an insert case attached to the heat sink and electrically connected to the stator circuit portion and the field circuit portion. A resolver input-output terminal is electrically connected to the control board by passing through an insertion hole provided to the heat sink. The rotating electric machine configured in this manner is compact and inexpensive with an excellent heat-releasing performance and a capability of reducing man-hours required for assembly and components required for connection.

Reinforcing body retainers are formed on an inner peripheral surface near a tip and near a root of first and second claw-shaped magnetic poles. Reinforcing bodies have a trapezoidal base portion and a pair of wing portions formed on two sides of the base portion, and slits are formed completely across a width direction of the base portion at a central portion in a height direction of the trapezoidal shape of the base portion so as to be offset toward a base of the trapezoidal shape. The reinforcing bodies are disposed so as to contact the inner peripheral surfaces of the first and second claw-shaped magnetic poles with a magnet housed and supported in each of the wing portions, and a D ring is fitted into the slits of the reinforcing bodies.

An automotive AC dynamo-electric machine is capable of providing a sufficient rotational output for starting an engine by running a rotor at high speed in a motor operation mode for starting the engine, thus obviating the need for increasing a size thereof. In the motor operation mode, an electromagnetic clutch follower connects to an electromagnetic clutch main body and also engages a cylindrical member to brake the cylindrical member. An internal gear portion provides a fixed element, and torque of a rotor is transmitted to a power transmission device via a rotor shaft, a sun gear, a planetary gear, and a carrier.
