Will this speed controller work with this blower? (details inside)

basically trying to find out if they are compatible, any electric hazards? few concerns...

1. controller mentions "For use with brush type motors only"... I am sure the blower is not bushless... is it?
2. Blower manual mentions that it will over heat if voltage drops... how does the controller work? does it work by regulating the voltage?






For those who wondering why I need this or what will I use it for, well... it will be part of a backyard science project for kids. Trying to create something like a floating t-ball sort of thing, even at the lowest stock speed this thing blows a LOT of air, need to slow it down, and hopefully it will make less noise too...

Thanks for looking.
 
That leaf blower most likely has a "universal motor", that is a motor with commutator and brushes and unregulated speed. Dropping the voltage will control speed. The most common way to do this is with a variac. The electronic controllers will work however depending on their method of voltage reduction they may cause singing noises from the motor itself.

It's common practice to warn of overheat/burnout with use of long extension cords of inadequate gauge (thickness). That is true with induction motors which the blower is not. It just won't spin as fast which in turn means it won't blow as hard.
 
You would probably be better off using a DC motor and regulating voltage.

Variable speed drives on 480 VAC 3-Phase motors change the frequency of the AC power to change the speed of the motor.

So basically the regulator will work, it will drop the voltage, but is a safe way of doing it? the burning of the motor warning just applies on using wrong long extension cord type?
