摘要： PROBLEM TO BE SOLVED: To effectively increase a torque in a wide rotational-number region by a structure capable of simplifying the winding structure of a dynamo-electric machine in a dynamo-electric machine driving system. SOLUTION: A stator includes a plurality of phases of stator windings 28u, 28v and 28w wound in a concentrated winding, and generates a rotating magnetic field of a frequency comprising a higher harmonic component by the flow of an AC current through the stator windings 28u, 28v and 28w.

摘要： PROBLEM TO BE SOLVED: To provide a rotary electric machine capable of increasing an output of the rotary electric machine by improving rotor teeth provided in rotors of the rotary electric machine.SOLUTION: A taper 141a is provided at a tip section 141a of the rotor teeth 141, thus making a magnetic resistance at a root 141b smaller than that at the tip section 141a, thereby easily transmitting a leakage magnetic flux M from a stator toward a diametric direction (Y) instead of a peripheral direction (X). As a result, the leakage magnetic flux from the stator can be sufficiently interlinked with a rotor coil, thus increasing an induced current flowing to the rotor coil, thereby increasing the output of the rotary electric machine.

摘要： PROBLEM TO BE SOLVED: To obtain a high-efficiency rotating electrical machine by suppressing the magnetic flux that flows in the direction of the axis of rotation.
SOLUTION: Permanent magnets 18 of a rotor have extended magnet portions 38, which extend outside both end portions of a rotor core 16 with regard to the direction of axis of rotation of the rotor. The magnetic flux 57, generated in the extended magnet portions 38, acts in such a way as to suppress the magnetic flux 56 which tends to enter the rotor core 16 and to leak outside, flowing through proximity portions 16a of the permanent magnets 18. Thus, the magnetic flux which flows through the proximity portions 16a of the permanent magnets 18 in the direction of axis of rotation can be reduced, and effective magnetic flux for the torque of the rotor can be increased.
