PURPOSE: To decrease the nonuniformity of the rotation of a motor. CONSTITUTION: A correcting signal for offsetting disturbance torque is written into a memory 112 in correspondence with the rotating position of a motor detected with a rotating-position detector 107. The signal is read out of the memory 112 after the one rotating period of the motor and added to the torque command signal of the motor. |
