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 using the same. The motor driving control apparatus includes: a back-electromotive-force detecting unit detecting back electromotive force generated by a motor apparatus; a floating correcting unit, if zero-crossing has not occurred in a current floating area, correcting the floating area by predicting a time at which a zero-crossing occurs; and a control unit determining a zero-crossing time of the back electromotive force based on an output from the floating correcting unit and controlling driving of the motor apparatus using the determined zero-crossing time.
