摘要：
An apparatus for controlling a speed of a fan motor (HIM (Hybrid Induction Motor)) of an air-conditioner extends a speed control range of a fan motor of an air-conditioner by controlling revolutions per minute (RPM) of the fan motor. In order to extend the speed control range of the HIM, an RPM of the HIM is controlled based on a pre-set duty ratio of a switching device electrically connected with the HIM.
