摘要： PROBLEM TO BE SOLVED: To allow rotor windings to generate an induced current without increasing a peak value of each phase current of stator windings while maintaining the balance of three-phase currents of the stator windings. SOLUTION: In order to allow rotor windings 18n, 18s to generate an induced current, a control device 41 controls switching operation of an inverter 40 such that a high-frequency component is superposed on each of three-phase AC currents of stator windings 28u, 28v, and 28w. The control device 41 controls the currents of the stator windings 28u, 28v, and 28w in such a manner that, when a current of one phase of the three-phase stator windings 28u, 28v, and 28w becomes almost maximum, each of high-frequency components, respectively having a phase opposite to each other, is superposed on each current of the other two phases and the average of the currents of the two phases is made almost -0.5 times the current of the one phase.
