ABSTRACT:
An apparatus for controlling a brushless type blower motor of an automobile air conditioner includes a rotational speed setting unit for setting a rotational speed of the brushless motor, a drive unit for driving the brushless motor according to the speed of rotation set by the rotational speed setting unit, and a switching control unit for controlling the excitation timing of the brushless motor achieved by the drive unit. The driving unit includes a waveform storage unit for changing the waveform of a voltage to be impressed to the brushless motor. The waveform storage unit outputs a sine waveforms, a trapezoidal waveform or a square waveform according to the rotational speed set by the rotational speed setting unit.
