Latching Hall-effect sensors, mounted in the motor, are used to measure the motor’s position, which is communicated to the electronic controller to spin the motor at the right time and right orientation.
Fans are used in a wide variety of commercial and industrial applications such as in commercial building HVAC systems, commercial kitchen exhaust systems, agricultural ventilation, and material handling.
