Ok, so I have a AC single phase motor that's 115 volts @ 1800 RPM. If I spin it 1800 times in a minute, can I produce 115 volts? (this would be a generator)
If the motor was a DC motor, then yes, they work very well as generators. As your question is regarding an AC motor, I'm not 100% sure, but I believe it would indeed act as a generator, although the relationship might not be 1:1.
You would have to energize one of the windings, but yes.
an AC single phase motor is not built to be a generator, and will not produce much in the way of a voltage when spun. The reason is the way the motor is designed to operate on AC without a separately powered field coil. the most common washing machine motors have a way to start with a Capacitor which provides some phase shift while starting to provide a moving magnetic field and this is switched out when running.
