<P>PROBLEM TO BE SOLVED: To provide an AC motor device enhanced in reliability and capable of being increased in torque. <P>SOLUTION: Single-phase AC currents are independently fed to mutually-independent three-phase coils 11 to 13 from mutually-independent three H-bridges 21 to 23. By this, the reliability of the device can be improved and the torque can temporarily be improved while suppressing an increase in the cost of the device. <P>COPYRIGHT: (C)2010,JPO&INPIT |
