PROBLEM TO BE SOLVED: To provide a conical or step-like gap type rotary electric machine facilitating its assembly, and achieving high torque and high efficiency by an increase in substantial facing area with a low-cost and highly reliable method.SOLUTION: In a rotary electric machine, there is provided a magnetic iron rotary electric machine stator in which a winding line shaft and a rotary shaft are perpendicular to each other, and an inner diameter part formed by distributing and arranging iron cores having m of the number of salient poles for winding lines in a circumferential direction is linearly or stepwise reduced in diameter as it goes from the front toward the back in a shaft direction. The stator faces a surface-magnet type rotor or an embedded-magnet type rotor in a rotatable manner. The surface-magnet type rotor is linearly or stepwise reduced in diameter as it goes the front toward the back in the shaft direction so as to form a tapered shape or step-like air gap, and uses permanent magnets on the surface thereof so that the n poles and s poles thereof are alternately magnetized to n poles in the circumferential direction. The embedded-magnet type rotor uses the permanent magnets embedded in rotor iron core holes so that the n poles and s poles thereof are alternately magnetized to n poles similarly. Here, m is an integer of 2 or more and n is a positive even number. |
