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

Dear MileHigh.

With respect, your statement above is incorrect.

On all but the most sophisticated Drill presses the drive motor's shaft speed remains near constant. Spindle speed change is effected by changing the drive belt ratios under the top cover.

Cheers Grum.

PS. There are also three rather nifty flywheels already built in !!  In the form of the Cast Iron multi stage pulleys. 

That's an excellent point.  In looking at Luc's clip it looks more likely that there is a belt drive for the drill press.  So I may be wrong in my earlier comments about this.  Another thing to consider is that the with the drill chuck assembly plus the rotor spinning at higher speed, there is more rotational inertia and so you are possibly back with a "smoother ride," especially for the motor itself.  Perhaps that partially accounts for Luc's observations at higher speeds but I am really not sure.

P.S.:  TK thanks for the vocabulary lesson!

Yes MH, the drill press is belt driven and not a direct drive. To change speeds you have to physically re-position the belt on a different  pulleys size. See pic

Thanks for your new update due to this fact

Good to clarify this.  My micro drill press has both a variable speed motor control and the 3 position stepped pulley arrangement.

And here's another test i did with a longer coil...

Hi,

Can you measure amps and make scope shot over 1 ohm resistor if possible?
The coil output power is interesting to see.

Out of curiosity, do you have any low power pulse motor to run your setup ? That would save lots of power input
If you can reach say under 5 watts input then you might try looping coil output back to pulse motor power source.

Cheers!

Hi everyone,

as some of us have been suspecting the higher RPM seems to be storing magnetic flux in the core and possibly if it has no where to go when coil is not under load it discharges or causes a braking effect when the C core changes phase which may be the slaps sound we hear. When the coil is on load the stored flux gets out so the C core makes it through to the next phase with ease.

Here is a test example of the prime mover input power when the drill press is at medium RPM range.

120w just turning the C core with I core away
140W with I cores in position and coil not on load
135W with coil on 1 Ohm load and delivering 5W to load.

So there's 10W which is not accounted for and it's hard for me to believe that so much power is being wasted in such small cores as Eddy currents and heat losses. At lower RPM there is less losses but also less output. It all seems to be linear and under unity.
If we could come close to a break even point I would say we are on the right track but it's not looking that good at the moment.
I have tried different load values, RPM's and so on but there is always losses.
I will still try different combinations and give an update if I find something better.

Please keep in mind what I'm testing is a variation of the original idea shared in this topic.
