MOTOR DRIVING CONTROL APPARATUS, MOTOR DRIVING CONTROL METHOD AND MOTOR SYSTEM USING THE SAME

摘要

There are provided a motor driving control apparatus, a motor driving control method, and a motor system. The motor driving control apparatus includes: a zero-crossing detecting unit detecting back electromotive force generated in a motor apparatus and detecting a zero-crossing point of the back electromotive force; a commutation point calculating unit calculating an average value for zero-crossing points detected at least three times to determine a commutation point using the calculated average value; and a control unit controlling a phase change of the motor apparatus using the commutation point.
