Make an AC electric sander motor serviceable for projects?
I am currently making an instructable that requires an electric motor. I have a Porter Cable electric sander motor that I was going to use for the project. The ideal motor for this project needs to be able to hook into a wall outlet and the speed of the motor needs to be adjustable by a rheostat or some other adjustable device. I recently tried connecting the AC motor to a wall outlet which in return the motor began to heat up and produce smoke while showing no movement whatsoever. I thought this would work because the motor had no power transformer attached inside the sander whenever I took the sander apart. The base of my question is: How do I go about converting the right amount of voltage or current so that I can use the motor to my discretion of speed?
