Experiments 10.2, 10.3 and 10.4

There are three experiments presented here. The technical settings of the experiments are displayed at the beginning of the experiments, in the videos.

1) Experiment 10.2: We apply sinusoidal torque at 1 Ampere for a few cycles, and then 2 Amperes for most of the 'active' part of the experiment i.e. that part of the experiment where all three sets of motors are working - the wheels are spinning, the subassembly is spinning and the main motor is spinning the cage.

2) Experiment 10.3: We apply sinusoidal torque first at 3 Amperes, then at 4 Amperes and then at 5 Amperes and then finally at 6 Amperes.

3) Experiment 10.4: We apply sinusoidal torque at 1 Ampere and then for 2 Amperes, keeping the wheels at 0 RPM.

The important purpose of Experiment 10.4 is to demonstrate that the cage undergoes ever increasing, gradual increase in rotational speed, making the experiment unsafe after a certain point.

Remember, that is just at 2 Amps for a few seconds. We see that in Experiment 10.3, we are able to apply up to 6 Amperes (fully 300% more), and not run the danger of uncontrolled acceleration! The reason is, I believe, that spinning wheels have this inductive ability to store and manipulate a lot of energy. In fact, they must be able to do more than that.  The spinning wheels in the prototype set up are somehow able to expel energy from the cage (or armature). There might be a connection between this energy expulsion process and the 'pitching' or 'elementary flying action' that the machine frame experiences with increasing intensity as we increase the max. torque of the main motor.

Note also that the entire frame is increasingly 'dynamic' as we increase the max torque.

I am considering continuing the experiments with higher and higher torques in the next week. Note also that the machine continues to spin around for a few rounds even after the sinusoidal pulses cease. This seems to indicate that the machine is operating in a 'free' state, rather than a 'forced' once that ceases as soon as the input ceases.

Clarification regarding my previous post, Experiment 10.1 : During the last few seconds of Experiment 10.1, the prototype (The one with the red tape on its back, to be precise) suffered a partial power outage. So if you look at Experiment 10.1 closely, you will notice that one of the wheel sub-assemblies stops spinning.

This of course renders the 'usable' portion of experiment 10.1 very short (the part where all the three sets of motors are on, the wheel motors, the sub-assembly motors and the main motor.) however, with these new experiments, we have more exposure to that crucial combination of conditions.
