ABSTRACT:
A rotor for an AC generator includes first and second iron cores which function as magnetic poles for the rotor and which are fixed to a shaft. A plurality of magnetic teeth project from the circumference of each iron core at a position where the iron cores contact each other to form troughs between the magnetic teeth. Each trough between the magnetic teeth is V-shaped, so that the weight of the rotor is reduced. Furthermore, each iron core has a ring recess portion at an outer end surface of the iron core and around the axis thereof.
