Title:
MOTOR CONTROL METHOD AND DEVICE THEREOF
Document Type and Number:
Japanese Patent JP3807335
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a motor control method and a motor control device displacing a movable part of the motor or a driven object driven by the motor in higher accuracy than in the past to a target displacement amount even when it is in a fine quantity.
SOLUTION: A CPU 2 of a motor control device 1 sets a conveying amount of printing paper to a conveying amount setting register 12 of an ASIC 3 to additionally read a voltage value corresponding to this conveying amount from a memory 18 set to a voltage value setting register 11. And a variable electric power source 9 sets voltage of the concerned variable electric power source 9 in accordance with this voltage value. A PWM generater 8 of the ASIC 3, based on a motor control signal (u) generated in a feedback arithmetic part 7 based on a count value (y) or the like of a rotational amount counter and the voltage value set to the voltage value setting register 11, sets duty ratio of a PWM signal supplied to a motor driver 4.
