THREE-PHASE MOTOR DRIVING APPARATUS AND THREE-PHASE MOTOR DRIVING METHOD |
摘要 |
The three-phase motor driving apparatus according to an aspect of the present invention comprises a controlling part that estimates a rotational position of the three-phase brushless motor based on a reference pulse signal output by the rotor sensor according to a rotational position of the magnetic pole of the first phase of the rotor when the three-phase brushless motor rotates, and controls the motor driver in driving patterns sequentially prescribed so as to correspond to the estimated rotational position of the three-phase brushless motor. |
