In HVAC variable frequency drives add energy efficiency and precise control for fans and pumps. The variable frequency drives offer demand control for airflow and water in chilled water systems, hot water systems, and air handling systems. Variable frequency drives require inverter duty motors and variable frequency drives can be purchased for three phase and single phase applications although the vast majority of variable frequency drives are used in commercial three phase applications. Electrical system âÛ" if variable frequency drive >25% of load, must take steps to mitigate; Frequent/constant running at full speed decreases efficiency and life of variable frequency drive; Alternative/Innovative Uses of variable frequency drives; Use to ...

Variable speed drives are ONLY for 3 phase motors, any method to speed control an induction motor. Variable speed drive with ONLY single phase input can drive capacitor start/run single phase motors. Variable speed drive operating from single phase have output voltage on each phase equal to input voltage. Higher capacity single phase motors with separate high torque/high current starting winding operated by centrifugal switch can not be used with variable speed drive. However a triac speed controller may work, as this could duty cycle the AC sine wave form. Try an off the shelf light dimmer and see if this can control the desired speed range of the fans. If this works, then some circuit research/lab work could produce a circuit that takes 0...
