Basically motors & generators are pretty much interchangeable. You'll find
that if you gear the "generator" up to a higher speed (5:1 is good), it'll
be harder to turn, but you wont have to crank as fast. Also, if there's a
big load on the "motor", the "generator" will get harder to turn.

| These motors, used in Mindstorms, have 3 programmed states: On, Off and Float. When 'On' the motor runs at the set power level. When 'Floated' the motor coasts to a stop (power removed). When 'Off' the motor brakes to a stop. This braking is quite (...) (24 years ago, 5-Oct-00, to lugnet.technic)
