Does anyone know of any websites to do this? I have an old 110v AC motor from an old vacuum.
Actually, almost any AC motor can be turned into a generator. Your AC motor will produce an output aafter you excite it with a quick hit with a vattery. Once you have AC, you can rectify it.
You can't, not without a lot of work. Easier to just get the correct type of motor. .
You try to modified the rotor as a permanent magnet rotor connect a suitable bridge diodes in out put winding get the DC..Best of luck .Other method you have to modified with extra winding with excitation may not suitable expensive..
