Re: Question for you guys that are tech savvy
A router speed control is designed for an AC/DC motor. It'll burn out a 1/4 HP motor which is fixed speed only (1750 rpm). 24 VDC is the way to go. Neil Morrison

Re: Question for you guys that are tech savvy
That is an AC induction motor. You aren't going to be able to vary the speed with a router speed controller. To vary the speed of that motor you are going to need a variable frequency drive for that.
