Mikhail wheel no mopre finger subjectiv feeling
Hi all After the good finger feeling from my previous video, i decided to become independant of subjectivness, and redo my test bench to get more precise results. So i mounted my 2 weights wheel on the shaft of a big brushless electric motor, I choose this motor , because under no electrical connection at all to any battery, the bearing and magnetic friction is important and present a suitable torque for the size of my wheel. Furthermore, i added some more resistance by shortcircuiting 2 of the 3 phases to get some more generative brake. This system is quite good and simple and can represent the OUTPUT torque. which stay almost constant for this test. Than i wanted a reliable INPUT torque, without measurement error. So i have some experience with a weight which unwind and simply measuring the timing of unwinding. So with those 2 input and output unvariable torque, each test is really reproductible. So i can make comparisons of different configurations on the main wheel and get some more credible result than the one i get with my finger feeling.. So in this test i could compare – first the wheel with fixed fulcrum , so the fulcrum are only some mass at the end of the wheel and we are here with a pure flywheel. – second the fulcrums are free to swing and we are more in the approach of the Mikhail system. So the results of this test shows that the flywheel needs about 15.15 seconds to unwind, and the Mikhail /woopy config unwind in 15.81 sec. I ofcourse redo this test a lot …
