Control apparatus of brushless motor and machine and apparatus using brushless motor

Abstract

An apparatus such as an air conditioner, refrigerator or washing machine having a control apparatus for use in a brushless motor facing a part of a compressor and/or blower of the apparatus. The control apparatus includes a voltage detector for generating a detection voltage in response to a terminal voltage of plural phases of a stator winding of the brushless motor, a standard voltage generator for generating a standard voltage, a comparator for outputting a comparison result information signal by comparing the detection voltage and said standard voltage, a controller for detecting a rotation position of a rotor of the brushless motor according to the comparison result information signal which is outputted from the comparator and for outputting an electric supply control signal, and an output unit for supplying electric power to the stator winding according to the electric supply control signal.
