Summary: | PURPOSE: A motor operating device and a method thereof are provided to accurately detect a current position of a motor by applying a weighted value to a count value according to a speed of the motor. CONSTITUTION: A speed detecting unit(120) detects a rotation speed of a motor according to an edge of a hole signal. The speed detecting unit applies a weighted value according to a reference count value preset in a clock signal count process set based on the detected speed. A position calculation unit(13) calculates a rotation position of the motor according to a count value of the speed detecting unit. An operating unit(140) operates a motor according to position information of the motor calculated by the position calculation unit. The speed detecting unit includes an edge detecting unit(121), an RPM detecting unit(122), a counter(123), and a clock signal providing unit(124). [Reference numerals] (110) Hole sensor; (121) Edge detecting unit; (122) RPM detecting unit; (123) Counter; (124) Clock signal providing unit; (130) Location calculating unit; (140) Motor operating unit; (AA) Operating signal |
