To improve electrical characteristics from the viewpoint of characteristics of a rotating electric machine, and also reduce an investment amount and improve labor saving and production efficiency in a manufacturing cost and management from the viewpoint of manufacturing, by reducing the amount of dies and jig or tools by unifying rotor iron cores and related components, even when the specifications and characteristics of the rotating electric machine differ.

Magnet loading holes 12A and holes as projected poles are formed into the same shape to an identical rotor iron core 11A, to enable loading of magnets 13A to the same holes. The number of the magnets 13A loaded to both holes and the arrangement of such loading are changed, to vary the ratio of the number of poles and magnetic torque and reluctance torque.
