Abstract

CEILING FAN Provided is ceiling fan (1) equipped with brushless DC motor (10). 5 Ceiling fan (1) includes duty instruction unit (6) that instructs an ON/OFF duty in PWM control of a switching element, and motor current detector (14) that detects current flowing through drive coil (2) of the brushless DC motor. In ceiling fan (1), a duty instruction value is determined by duty instruction unit (6) based on a detection value of motor current detector (14). According 10 to this configuration, ceiling fan (1) that can blow air by rotating blades at constant and maximum torque without being affected by a change in the distance between the blades and a ceiling due to the installation state of ceiling fan (1) can be provided.
