DougStealing a few minutes from mortar and stone, I am working on our daisy chain motor experiment of six or is it eight years ago?Anyway, I am very much more careful with exactly separating the source DC from the back EMF noise capture.With just two motors, using two plain blocking diodes, a few minutes ago, both motors are running on 15 volts. There are 90 volt motors. The EMF motor is a very substantial gear head and is turning just fine, and there is nothing I have handy that is going to stop that shaft.The adjustable regulated power supply is reading less than 1 amp load.Must check if it changes with the additional motor.I will keep adding motors as I epoxy the magnets back down.Sitting in unheated spaces and being knocked around loosens the magnets on most DC motors. There are extreme temperature issues with the differential of expansion of materials, like steel and those ferrite magnets, I suspect.No permanent damage that 5 minute epoxy can't fix. Each one must be taken apart, and so on.Nylon fish line is your friend with the brushes to re-assemble. That, and masking tape.So good so far!Cheers Warren

Hi Warren.
I dunno...2A and 24V...48W...thats lots of power input.
Only going 800rpm or so
My muller gen with flat disc flywheel of 16 20mmx5mm neoymiums goes 620rpm at 15v and .20 amps: so .3watts (point 3)
Not to brag eh!
His flywheel power measurements have no mechanical load resistance so that actual HP can be measured ...looks like his measurements/calculations are only of a spinning mass and how much energy is stored within (but not actual power since no mechanical resistance is being applied so as to.be able to measure torque)
He could have a generator hooked to it, as a load too (of course generator not lenz free type)
Or Prony brake on shaft:
