The new generator no effect counter B. EMF part 2 ( Selfrunning )

Mister Caribbean Roots:

Well, it's really up to the builders if they want to know about someting or not...it all depends on what the purpose is when you build something... (http://overunity.com/Smileys/default/wink.gif)
Do we want to learn about something and maybe improve it or do we just want to replicate it as a fun hobby project...

I can't disagree with you there.   However, if you are going to get technical and share technical information with your peers, then you want to say things that are correct and make sense.  You have a responsibility to do your own checking.  So for example, there is no "delayed Lenz effect."  Likewise, if you say, "When I add a generator coil to my pulse motor the the RPM decreases and the current consumption increases. Therefore the added mechanical load of the generator coil is the cause of the increased current consumption."  With a pulse motor, as we now know, there are many things that can affect the current consumption so that statement is not necessarily true.

What is your take in regards to coil resistance MH. Is it better to have a coil of high resistance(many turns of small wire),or a coil with low resistance(few turns with a larger gauge wire)?. We will say our pulse motor will be useing a 12 volt power supply for the P/in.Our coils will be of the air core type. What coil would produce more losses in an identical setup?.

Tinman usually one figures out the voltage / current versus turns that can be supported with an acceptable temperature rise for a given winding shape.  Then the choice of wire diameter is made based on the maximum voltage of the available power supply and whether or not a chopping drive will limit current.   If no chopping is used, then temperature rise is the usual criteria.

OK,i will make it a little clearer.
We are building a pulse motor(lets just say a simple SSG circuit).We are looking for torque and inductive kickback collection.We are useing a 12 volt battery as our P/in sorce,with a limit of 250mA for I/in. Our air core coil formers are of a fixed size.

So what we want to know is-->what would be better ,lots of turns of a smaller gauge wire(higher resistance) or fewer turns of a larger gauge wire(lower resistance)?.Which coil would loose more to heat?,which coil would produce a stronger magnetic field for the P/in avaliable?.

These are things i already know,and the questions are just to see and help those that may not know the answers to these questions.

What are you relying on to limit the current to 250mA?  If it is the winding and you would not saturate any magnetics at 250mA times the number of turns, then you would design your winding for 12V/250mA = 48 Ohms.
