Bwuahahahahahahahahaahahahaha!

What part of the word "permanent" do you not understand?

Sam My Boat is so small.(just a barrel) Still wind was first used and
every motor has a fly wheel. Flywheel can store energy. They are
protential energy and go round and round I like that feature TreBert

How odd, i can't think of an electric motor nor a turbine that has a flywheel.

I have seen more than one electric motor with a flywheel.

(1) On a quite seriously fast punch machine for making the E core
shapes
out of sheet metal, the motor had a flywheel and the mechanical bit
went
bang-bang at about a 10Hz rate cutting the metal.

(2) A little toy electric motor had just one coil and contact and
worked a
little like a 2 stroke gas engine.

You should think a lot more. Rotor of electric motor is very heavy and
acts like its flywheel Same is true for the heavy blades of turbines.
Best read up on diesel electric trains. TreBert
