<P>PROBLEM TO BE SOLVED: To provide a controller of a motor capable of improving response at the time of changing a relative displacement angle by efficiently raising the temperature of a working fluid. <P>SOLUTION: The controller is for a motor 10 which includes an outer peripheral rotor 21 and an inner peripheral rotor 22 provided concentrically around a rotating shaft 12, and a rotary mechanism 30 which is arranged to adjoin the rotors 21 and 22 for changing a rotor phase difference in circumferential direction of the rotors 21 and 22 by a fluid pressure of the working fluid. It includes a working liquid supply part 150 for supplying a working fluid to a lead angle side working chamber 42 and a delay angle side working chamber 43. An ATF state detector 152 or 154 for detecting a viscosity or a temperature of the working fluid, an actuator 125 which controls a flow rate of the working fluid supplied to the working chamber 42 or 43 by the working liquid supply part 150, and an ATF control part 153 which controls the working liquid supply part 150 to supply the working fluid to the working chamber 42 or 43 if the detected viscosity or temperature of the working fluid has a value within a predetermined range when the actuator 125 is not working. <P>COPYRIGHT: (C)2011,JPO&INPIT |
