| 摘要 |
<p>The present invention relates to an apparatus for driving motor. It comprises: a reference voltage generator which generates at least one reference by using a neutral point voltage of the BLDC motor; a motor driver which generates PWM signals to detect a back-EMF zero-crossing-point (ZCP) of the each phase by comparing phase voltages of the BLDC motor′s each phase and to control the switching action of the inverter and the phase voltage of the each phase by using the ZCP, location information and so on.</p> |
