Abstract
To reduce a torque ripple during a pressing operation, while achieving an increase in generation torque to the pressing operation.SOLUTION: A motor controller 10 controls energizing current of a motor 22 in such a manner that the maximum torque is obtained with respect to a current command value for generating torque, when making a moving body 27 approach a work-piece 30, and controls the energizing current of the motor 22 in such a manner that a variation width of the torque with respect to the current command value is more reduced than in a case of controlling the energizing current of the motor 22 so as to obtain the maximum torque, when pressing the moving body 27 to the work-piece 30.SELECTED DRAWING: Figure 1
