<P>PROBLEM TO BE SOLVED: To provide an efficiently driven rotary electric machine. <P>SOLUTION: A rotary electric machine 10 comprises a stator coil in multiple phases; and further comprises: a stator 12 for generating stator magnetomotive force depending on stator current in different phases respectively provided for the stator coil in the multiple phases; a rotor 14 on which a rotor coil is winded so as to generate rotor current depending on a stator magnetomotive force generated by the stator 12, and to form a magnetic pole by the rotor current; and a controller 38 for controlling stator current so that output torque from the rotor can be controlled. When the rotor 14 outputs prescribed torque, the controller 38 gives pulse to the stator current so that the stator current (rotor current) increases while the rotor current (stator current) decreases in a case with high temperature of the rotor 14 (stator 12), comparing to a case with low temperature thereof. <P>COPYRIGHT: (C)2013,JPO&INPIT |
