Can a Solid State Speed Control be used on a Belt Drive Fan?

Greenheck does not offer solid state speed controls on belt drive fans because in order to use a solid state speed control, the motors have to be either a PSC (Permanent Split Capacitor) or Shaded Pole type. These types of motors are not used on belt drive fans because they have very low starting and running torque. Belt drive fans have added torque requirements due to bearings, belts, and pulleys, all which hinder the ability of the motor to start the fan or even keep it running if the voltage is dialed down on the speed control.
