<P>PROBLEM TO BE SOLVED: To provide a controller for a motor, stably operated without vibrations within all ranges in use conditions and providing the same operability and operational feeling as a hydraulic driving system by a control based on a simple algorithm. <P>SOLUTION: The controller for the motor has a motor control means controlling an output torque from the motor on the basis of each detecting value of an operation detecting means and a rotation detecting means, and the output torque is determined in response to a manipulated variable and a rotational speed. The controller for the motor makes at least either of the control gradually reducing the maximum value of a power-running torque when the rotational speed is increased, and the control decreasing the maximum value of the power-running torque when the rotational speed is increased in the vicinity of the maximum value of the rotational speed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
