you say "what happens for the drive motor at Zero RPM, if there is nothing that is consumed in the motor, there is no movement, there is no energy expenditure."
This condition, zero RPM with power to the motor, is called stall. And the motor produces "stall torque". Look it up, please. At stall torque, the power output on the shaft is zero. (Power = torque * speed) However there is input power to the motor. (Power = voltage * current) So there is energy expenditure in the motor and the reason the motor will overheat. There is just no mechanical energy conversion taking place in the motor. So no energy or power delivered to the generator at stall.
When starting, at zero RPM, the motor is at stall. There, by definition, 0 RPM, no movement, no power transmitted, no mechanical work done. All that starts at "0+" RPM, at "0+" seconds after motion commences. Use calculus and infinitesimals to understand this.
When starting from 0 RPM, torque is needed to accelerate the mass of the rotor, both motor and generator. That requires power input to the motor. Once rotation starts, power from the motor is required to overcome friction and windage and magnetic drag which is caused by eddy current and hysteresis losses heat in the core(s). All of that required power is independent of cogging.
Energy used to accelerate the rotor is stored as kinetic energy in the moving mass. Energy used to overcome friction, windage, and core loss (magnetic drag) is lost as heat. Cogging is essentially net zero regarding energy consumption meaning it is not a loss factor. Cogging is torque aiding rotation approaching TDC and torque opposing rotation departing TDC. Of course if your motor, or hand, has insufficient torque to overcome the initial requirement (breakaway), rotation fails.
At rated RPM constant speed, power is required to overcome friction, windage and core loss. No power is required by the moment of inertia (rotor mass). No power is lost to cogging. Once electric load is applied, power is converted from mechanical to electrical in the generator therefore more power input from the prime mover is needed.
Don't just take my word for this. I don't want you to. Look it up. Study the science and learn the truth, facts and the way things actually work.
I'll run the little test when I get to it. But it really doesn't matter. Just like cogging doesn't matter. The only thing that matters is proof of Turion's extraordinary claim of a tabletop 1700 watt free energy device.
Just consider what I say and research it. You'll learn that I'm right and Mr. Turion is not.
