Ah. So this is a miniature dynamometer. I guess it acts as a brake
slowing the thing down to some extent while measuring RPMs. The big
dynamometers I have seen work that way.
I have an indoor bicycle trainer which is supposedly very stable and
accurate, calibrated by the factory. It has fluid that produces
variable resistance increasing with speed, mimicking the effect of a
headwind. A speedometer on the bicycle monitors RPMs and displays
speed, distance and watts. I guess that would be a dynamometer of sorts.
