However, I do expect all to stop running when the stored energy within the device is exhausted. This will be manifest by a reduction in rotor speed over time.

hi Hoppy

i'm interested to know what stored energy you believe there to be in Romero's system


i can see that the 47000uF capcitor is one store of energy - at 12V it stores less than enough energy (approx 4 Watt-seconds) to sustain the 12W motor drive for half a second

the rotor inertia is a second store of energy - spin-down from switch-off at regular running rpm sustains rotation at a decreasing rate for around 100 seconds


what is the third (and any other) store of energy which you see as sustaining operation (with & without additional electric load) for the remaining approx 15 minute runtime during Romero's video?

15 minutes of motor drive requires an energy input of 10.8 Kilowatt-seconds

where do you see  this 10.8 Kilowatt-seconds  as being 'stored energy within the device'?

Hi np,

No more than you have stated, which is why I see all replications running down to a stop.

?!?


what i stated accounts for much less than 100-and-a-half seconds of operation


i asked you where you see the OTHER 10.8 Kilowatt-seconds being stored in Romero's system, which is how much stored energy would be required to  keep it operational for the remaining 900 seconds of his video?

thanks
