I admit that the efficiency depends of torque and speed but It’s quite difficult to have a right model. A good aproximation per example will be with the theory of Hertz contacts of Hookes Theory (with finite element modelling). But my software is very simple. I can’t introduce this type of theory with theory.
For the RPM, calculation is made with value in charge, mesuring by me. And I mesure the same speeds as philo.
I am waiting for your result and your detailled operating experiment.
Thanks for your comment ;)
