ZERO CROSSING POINT ESTIMATING CIRCUIT, MOTOR DRIVING CONTROL APPARATUS AND METHOD USING THE SAME |
| 摘要 |
A motor driving control apparatus may include: back-electromotive force detecting unit detecting back-electromotive force generated by a motor apparatus; a zero crossing point estimating unit estimating a zero crossing point by performing at least one of differentiation and integration on a voltage difference between the back-electromotive force and a preset reference voltage; and a controlling unit controlling phase switching of the motor apparatus using the zero crossing point. |
