Question by Donald M: Is using an old Makita power tool a stupid idea if I want a low voltage generator?
I am trying to make a microhydro electric power device.
Could a guy use the motor from a power tool as a generator??? Any Suggestions?? – It is a class project and I am the teacher.
Answer by Mastermind
Most all electric motors run in reverse (you turning the shaft) will generate electricity. For a hydro device one of the main things you want to look for is the torque needed to turn the electric motor. Some motors (generally the bigger they are) will require more torque to turn that others (a RC cars won’t require much). You may find some are so hard to turn that it isn’t practical to try to turn them using water power without a fancy setup. Other than that you should be fine with pretty much any electric motor.
