    • 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. A rotor includes rotor windings arranged at a plurality of positions in the peripheral direction and diodes rectifying the currents flowing through each rotor winding. The magnetic characteristics of magnetic poles at a plurality of positions in the peripheral direction generated by the current flowing through each rotor winding are made to differ alternately. The dynamo-electric machine driving system includes a switch 42 superposing pulse currents to stator currents flowing through the stator windings 28u, 28v and 28w only when the inter-phase voltage of the dynamo-electric machine 10 or a value corresponding to the inter-phase voltage is less than a threshold value or equal to or lower than the threshold value and when a preset pulse-superposing request condition holds.
