if one had ideally set up pulse motor with GENUENE zero cemf,would it guarantee ou?

That is going to be a tricky question to answer.  Would it be TRUE OU, I guess we will have to wait and see, because to my knowledge, there does not appear to be a situation I'm aware of that has tested this as of yet.  At least I'm not aware of it.

But the real question is this...  Just because you get more mechanical energy out, than electrical energy you put in... How useful is it even if it's OU...  It's like comparing apples to oranges, and the only way to know the truth is using equations.  This is why so many people do not take the road of using a pony brake to prove anything.  Most of us agree, a pony brake will prove things, but if we put electrical energy into a system, we need to see electrical energy back out, and compare apples to apples.  It's the conversion process of going back to same type of energy as you started with that most of us are concerned about.  Even though I totally agree, measuring the mechanical energy out, and heat and friction loses, and comparing to electrical energy in will give you the answer.  But what good does that do us?

Prony brake
Hola.
La fabricación de un Prony brake para medir una energía tan pequeña como 1watts requerirá de un esfuerzo grande.
Como cada vez que se pone en marcha uno de los dispositivos que se están probando tiene lugar un aumento de la velocidad, hasta que ésta se estabiliza, es más fácil calcular la energía necesaria para aumentar la velocidad en un intervalo de tiempo dado, y a su vez determinar la energía empleada durante ese período de tiempo, empleando para ello el consumo de corriente y el voltaje.

Hi all
Thank you powercat and captainpecan for your answers,if there is such a motor,would it  follow that a genny working on the same principles,but in reverse,would have no bemf?

@powercat,

>>a lot of people have built motors  with no attempt to generate power

I have made a version that also had a generator output coil.
My solid state has an output generator coil also.
And I posted both in this thread.

Groundloop.

Working on it too...
