Abstract
This invention provides a rotary electric machine with a high productivity/maintainability. Since the shaft portionor the stepwise drawn portion is formed with a flat faceperpendicular to the rotational axis, when the magnetic polesare bonded to the rotor, an accurate gap control can be achieved by applying a certain pressure to the magnetic poles with a jig or the like using the perpendicular flat faceas reference, or by controlling the distance from the perpendicular flat face
