Motor control device and motor control method

摘要

A motor control apparatus and a motor control method according to the first embodiment of the invention are configured to instruct deenergization of a motor a predetermined period of time later than arrival of a subject to be driven by the motor at a speed measuring position, the predetermined period of time corresponding to a current speed of the motor upon arrival of the subject to be driven at the speed measuring position, and the speed measuring position being at a predetermined distance before a target stop position of the subject to be driven. A motor control apparatus according to the second embodiment of the invention includes a position detector (6a) for detecting the position of paper driven by a paper feeding motor (1) on the basis of output pulses of an encoder (13) that rotates in response to rotation of the paper feeding motor (1); and a drive controller for controllably driving the paper feeding motor by additionally applying a current value to the paper feeding motor on the basis of a target value of the paper feeding amount and an output of the position detector (6a), and it is characterized in generating a current value signal that causes the paper to stop or rotate in the reverse direction from a normal paper feeding direction in response to output pulses of the encoder after the paper feeding amount reaches the target value, and controllably driving the paper feeding motor with the driving controller in response to the current value signal. <IMAGE>
