APPARATUS FOR DRIVING BRUSHLESS MOTOR FOR OUTDOOR FAN OF AIR CONDITIONER

摘要

PURPOSE: An apparatus is provided to easily control the stop for braking, stopping and deciding a position even if a fan driven by a brushless motor is rotated by external elements. CONSTITUTION: An apparatus for driving a brushless motor is composed of: a single hall IC(2) for detecting the stimulus position of a brushless motor; an inverter circuit(3) having plural switches bridge-connected to feed or isolate electric currents; and an MCU(100, Main Condensing Unit) turning on/off the switches of the inverter circuit on the basis of an output signal of the hall IC.
