In creating energy from a magnetic wheel or a gravitational wheel how do you connect to create an energy source?
If you mean the mechanical coupling of a generator and an electric motor, then you can have direct coupling, or by gearing or with belt. However, my worry is you might be speaking of a motor driving a generator and getting its power input from the power output of the generator. That of course is not possible since at most the generator can produce only the electric energy equivalent to the mechanical energy supplied to it. But any conversion from one form of energy is always accompanied by losses; therefore, the system will never work for even a short time.
When I read the short version of the question: How do you connect an AC motor to a rotating device to create an energy source? I was ready to answer it: While you can't create energy you can convert the mechanical energy of the rotating device to electrical energy. While typical AC motors are not designed to be good alternators (AC generators), if you are lucky one can use a motor, just connect it to your rotating device (perhaps a flexible coupling or belt drive would be a good idea to make alignment easier) and see if electricity comes out. If it doesn't, a short pulse of DC may get it started. But again, it may take some luck to get a motor to work. If you actually had a rotating device that was transforming some other source of energy (maybe falling water, wind, steam, etc.) you would be better off buying an alternator that was designed to be an alternator, for small projects a used automotive alternator might work. But then I read magnetic wheel or a gravitational wheel. This creates a problem for making an energy source, but you could use it to make an energy sink (or space heater), in this case the motor will be ideal, connect the motor to your device and to the electricity provided by you local utility, then your magnetic wheel or a gravitational wheel will convert power supplied by the utility to heat. Perhaps not much heat if you have good bearings, but even then, hysteresis effects or just air resistance will cause some drag.
