this is a mechanical resonance machine with kenetic and potential energy being transferred between flywheels and springs. the difference in mass/radii of the 2 flywheels sets the resonance frequency. that's why it speeds, up, the resonance rpm is higher than the original speed, as the smaller flywheel on the outside stores excess potential energy and transfers it back to kinetic energy in phase with the springs. it is a 2nd order differential equation with the 2 masses and springs. all that would stop this resonance is a load, or else friction will wear it out to a standstill just like spinning a top eventually loses its stability. t. electrical engineer / physicist
