<P>PROBLEM TO BE SOLVED: To provide a controller of a motor in which conduction control can be performed efficiently depending on the operating state of the motor regardless of the number of revolutions of the motor when the motor having two rotors arranged concentrically is operated. <P>SOLUTION: When the magnitude of a composition vector of a command value Vd_c of a d-axis voltage and a command value of a q-axis voltage of a motor 1 becomes larger than a radius Vp_target of a target voltage circle, a means for coping with a voltage rise between terminals performs at least one of "first processing for coping with the voltage rise between terminals" where a rotor phase difference is altered in the direction for reducing the field magnetic flux of the motor 1 by means of an actuator 25, "second processing for coping with the voltage rise between terminals" where an output voltage Vdc from a DC power supply 100 is increased by means of a DC-DC converter 101, and "third processing for coping with the voltage rise between terminals" where a d-axis current is increased by means of the DC-DC converter 101. <P>COPYRIGHT: (C)2008,JPO&INPIT |
