Is it possible to make a hand-cranked motor out of a sewing machine?

Does the electric motor have permanent magnets in it? Some motors use electromagnets to generate the magnetic field which means you can't use them as generators since you've got the Catch-22 of needing power to generate power.

Even if it's a permanent magnet motor you'd need precise speed control to generate the 120v 60Hz most appliances need. Something simple like a lightbulb or heating element will handle whatever random RPM you can produce, but not a laptop charger or monitor.

How can I tell which is which? Electromagnets would be just a coil of wire around a piece of metal, right?

basically, yeah

ANS: probably not but even if you did it would be pretty worthless except as a science project / experiment.

too much work for too little return

Put a screwdriver or anything else ferromagnetic next to it. Do you feel a pull from permanent magnets?

Theres a video of a professional bicyclist powering a generator with a stationary bike- the only thing plugged into it was a toaster. Guy almost passed out from the effort.

You can spin a generator my hand to light an led bulb- but more electric load = more effort to turn generator.
