Axial fan motors that are rated for 480V 3-phase power are used to power large axial fans, which are commonly used in industrial and commercial ventilation and cooling systems. The fans use an electric motor to drive a propeller-like blade that moves air along the axis of the motor, hence the name "axial fan."
The 3-phase power supply provides a high level of electrical power to the motor, which allows it to operate efficiently and effectively. The 480V voltage rating is typically used in commercial and industrial applications where high levels of electrical power are required. The 3-phase power also provides improved performance and greater reliability compared to single-phase power systems.
