ることを特徴とするモータのトルク制御装置。[Scope of claim for utility model registration] A device that controls the rotation speed and torque of a motor so that they have a predetermined relationship, which stores data indicating the relationship between the current, torque, and rotation speed of the motor, When setting data indicating the relationship between the number of rotations and the torque is input, a current conversion unit creates data indicating the relationship between the current and the rotational speed based on this setting data and the stored data; a current command section that calculates a current value corresponding to the detected rotation speed based on the data created by the current conversion section and the motor rotation speed detection value, and outputs this current value as a motor current command value; 1. A torque control device for a motor, comprising: a control unit that controls a current of the motor so that a detected current value of the motor becomes the current command value.
