Hi Groundloop,

I see now, he is showing the ferrite core of each coil magnatized and thus being magnatized, it is indeed in attraction mode to the rotor magnets.  Perhaps that is what he meant.

Cheers,

Bruce

Further to Bruce`s post above . How to make your own Litz wire for these coils . Get some enamelled wire with a diameter of 0.125 mm . Your local electric motor rewind shop is a good source .This wire is very thin so work carefully . First and hardest part is estimating the length of wire needed for each coil .Let us guess , an average length of one inch per turn . So 300 turns would be 300 inches or 25 feet . If your workshop is less than 25 feet long , work outside . Mount 2 hooks 25 feet apart facing each other , on wall bench clothes posts etc . Attach the loose end of your wire to a hook , walk to the other hook , loop the wire round it and walk back . Walk back and forth 7 times , looping at each hook until you have made 7 trips .Tie off the wire at the hook and cut the wire . Bind the 7 strands together with tape near each hook . Now slip one end of the bundle off a hook andput a screwdriver through the loop where the hook fitted . Use the screwdriver to twist the strands together loosely . Cut off the loop at one end and carefully remove the enamel and solder the wires together . Use this end to start winding your coil , and wind the desired number of turns .You will then probably find your bundle was too long .cut off the excess and measure it .   Subtract its length from 25 feet , and adjust your hooks for the next performance . Finally strip and solder the ends together .Hope this will help someone .

Hi Groundloop.
thanks for the updated picture, but this
could be a bit misleading, as the core of the driver coils are still
ferrite and no magnets.
So maybe you can change it this way, that you just only paint North and Soutpole
by letters there and write beside it, that these are the generated fields from the transistor driver ?

Many thanks.

Regards, Stefan.

Hi All,
here are now the backups of the RomeroUK Videos:

http://www.youtube.com/watch?v=8KVU3ZM14rw

http://www.youtube.com/watch?v=o3YqCp84IOE


Romero, how many times per revolution of the rotor disc is each
driver coil pair energized ?

8 times ?

But each driver coil pair is out of sync to the other driver
coil pair, right ?
So there are 8 + 8 = 16  driver coil pulses per revolution
of the rotor disc ?

Do you have a scope , so you could show the waveform on
one of the pickup coil pairs ?
That would really help to analyze it.
Many thanks.

Estimates for coil wire length

my cores are 15mm x 10mm

15mm (ferrite core) / 0.6mm(wire diameter) = 25 (turns per layer)

300(turns) / 25(turns) = 12 (number of layers)

Layer 1; 10mm dia x pi = 31.4mm (per turn) x 25 (total turns for layer) = 785mm

Increase core dia by 1.2mm for each of the 12 layers

I calculate for 12 layers of 0.6 wire on a 10mm core will total 15.637metres

I hope this helps

Hi Romerouk
As neptune suggested with ceramic magnets from microwave ovens
Im interested with the output  wattage it can produce????? ???
Also instead of the driver coils ,   i will try  the rotor from a vacuum machine  with carbon contacts  direct dc  to rotate the magnets

Trying to replicate the set up on a low budget
cheers  and regards to Groundloop ::) ::)

@bourne. many thanks for that calculation . With home made multistrand  it will never wind as neat as you expect . I recomend adding 40 to50% to the calculation for the first try . Then you can refine the length as  I previously said .

@neptune.

Thanks, It's an 'ideal world' calculation and of course does not include tails and imperfections.

I thought I would post it because the difference between layer1 (785mm) and layer12 (1821mm) is quite large and may lead to underestimating the length needed to complete 300 turns.

This is a great thread.

thanks thats a great idea
I have the wire never accrued to me to wind my own.

@toranarod .Poverty is a great educator ! Pleased to be of service ,but thats what these threads are for .If we all put something in , the net result will be wonderful .Thanks for posting the rotor diagram . Do you plan to one for the stator please .

(Hi, I am still not 100% clear on the electric circuit in how the remaining things are connected, in which order and where to. I have now drawn a picture, can someone look at it and correct it if its wrong and clear up the few points )


EDITED: picture corrected, after schematic from Groundloop, and tipp from gyulasun

7 X 0.125MM SOLDERABLE STRAND EN.Cu 500g

If the wire comes in 500g rolls anybody know how much we would need to make all the coils in the motor?
any ideas Please?

can i say this is very helpful it would be very close if not correct
thanks
