APPARATUS FOR DRIVING MOTOR AND CONTROLLING METHOD THEREOF
摘要
<p>An apparatus for driving a motor and a method for controlling the same are disclosed. According to the present invention, the apparatus for driving a motor comprises: a rectifying part which generates a direct current power source (DC) by rectifying an input power source (AC); an inverter which applies the direct current power source to each phase of a motor through a switching operation; and a motor driver which converts a value of a counter-electromotive force which is sequentially treated by sampling in a floating section of each phase into a digital value, and detects positional data of the zero crossing point (ZCP) of each phase through a pattern of counter-electromotive force which is formed using the value of the result of a comparison between the digital value and the value of the reference voltage.</p>
