Is one of your new mini-split units going to be near a return air vent? If so, running just the fan should work rather well. If not, where does the return air come from? Hmmmm.....

The fan motor you linked to is awesome. Five speeds to choose from, all at high efficiency. Carrier and Trane are installing these types of motors in their new variable speed, variable capacity split systems (both indoors and outdoors). If it fits your existing blower, it should save much energy over a shaded pole motor and some energy over a split capacitor motor. At $250, not a bad price for a new motor. However, it could take many years to pay its cost back in energy savings. The more it runs, the more it saves.

I figured Mike would like it, it has FOC. They call it speed defined torque control.
