I need to change out my motor on my Singer 1191 d300a. It now has a 12v, 3500 rpm on it. It's getting hot, my husband would like to change it over to an ac motor. He thinks a regular sewing machine motor will work because it is a 7000 rpm. I think it won't because it is a smaller motor.

Here is the question, would the 7000 rpm, ac motor, be equivelant to a 3500 rpm, 12 volt.

I know it will have to be rewired and some rigging it up so I can use a foot peddle.
