Hi, thanks for the info. Can you explain how a lever works?

Gravity will pull the weights towards ground all the time, with equal force at any time
  ;)And how the gyroscope which has unusual gravitational properties?

Hi, thanks for the info. Can you explain how a lever works?

What do you mean? A lever is a lever. A mass that is lifted a given distance in altitude, it does not matter how you do it. The energy you put into the lifting process is the same if you lift it directly or using pulleys, levers or what not. Don't confuse force with energy. Energy is a product of force and distance.

Hi, Direction of the rotation will be in the of direction of higher torque. The weights falling are the real input. As the weights fall toward the rotating center of gravity they will produce a total torque at the output. A DC Buck circuit with a variable duty cycle can be adjusted to limit the load to less than the total output torque.  All motors operate at a loss. I have to fabricate a few more parts than I can test and post results.

When the weights has reached highest torque, what happens next? At some point these weights must repeat the cycle and pass a point with least torque. From where do they get the input to repeat the cycle with even more energy?


Torque isn't all. Examine at what angular velocity the mass has at a given torque.


As long you use gravity to "gain" torque, and the mass is unchanged, the complete cycle will allways end up in loss. There is no way around this - really.
