This type of ceiling fan utilizes a belt and pulley system to rotate the fan blades. A motor drives a pulley connected to a belt, which in turn drives a second pulley attached to the fan’s rotor. This system differs from the direct-drive mechanism found in most modern ceiling fans, where the motor is directly connected to the fan blades.
The belt-driven mechanism offers several advantages. It allows for larger fans to operate efficiently and quietly, as the motor can be placed further away from the blades, reducing noise and vibration. Historically, this design was prevalent due to limitations in motor technology. While less common today, this approach remains relevant for applications requiring powerful air circulation and quiet operation, often found in larger spaces or settings where noise reduction is paramount.
