I finally got to finishing my version of Lasers motor. I dont have a lot of time to spend as much as I used to. But its done and it works. Im doing a rundown with a 1000uf cap right now. Started at 35v and has been 22 min and we are down to 15.2v. So it works as described.  ;) Thanks Laser. ;D And Im working with graphite treated bearings instead of needle bearings. I was worried a bit cuz I know the needle bearing has virtually no resistance, where I have more Im sure.

I did not even try much timing yet. Got to get to sleep as I didnt get much sleep last night and was dragging at work.

Heres a couple pics. Will do a vid tomorrow.

Oh, the reed holder is temporary till I get the dual read switch holder/adjuster completed. This one I used plastic tubing and attached the reed to the outside and I have a small neo connected to the end of the clear plexi rod inside the white tube to adjust the lil neo towards the back of the reed to bias it for N pole magnets as I have alternating NSNS on the rotor.

The dual reed concept will have 2 phases where 1 reed fires and when it opens, the coils will dump what ever field collapse current into the other phase cap and vice verse. So 2 individual drive circuits which dump collapse current to each other. Im going to check to see if the is any bemf, as the might not be much due to 15.36kohm total series coil resistance. But still want to do the dual reeds regardless.

Hi Mags,

Very nice build, hats off! Thanks for showing the results.

Just out of curiosity, I was playing with some numbers in this link http://www.circuits.dk/calculator_capacitor_discharge.htm where I entered your 35 V as max and your 15.2 V as minimum cap voltages, for ESR I used .03 Ohm (not critical for such calculations at microAmps)) for the 1000 uF capacitor. I found that entering about 22.2 uA as Imax current I got 1320.3 seconds for the resistor load cap discharge. (Your 22 minute long run time was 1320 seconds.)
If I choose the constant current discharge time to be 1320 seconds, then the Imax is 15 uA and the load impedance 2333.3 kOhm
This calculation indicates that your series coils (with the duty cycle defined by the reed on/off and the rpm) represent a 1582.99 kOhm load for the capacitor in the resistive discharge and a 2333.33 kOhm for the constant current discharge.
This load is the series inductive impedance of course and includes the 15.36 kOhm copper resistance, the total coils impedance being also increased by the duty cycle.
So your max current consumption if I am not mistaken much may have been between 15 to 22 uA, you may have a chance to check it, just for curiosity.

Looking forward to the collapsing field's energy capture, hopefully the dual reed contact will be speedy enough not to miss too much from the event under the switchover time.  The energy stored in the series coils is given by  formula  .5*L*I2 and it remains to be seen how much energy you find ( .5*C*U2) as going  into the other phase cap from the process.

I should have waited till tomorrow. lol Im beat. But I did it anyways. http://youtu.be/QyU0H_kJLxQ

My camera seems to only want to do 10min, 9min, vids then stops. I checked the menu and dont see a setting for that. And its a 4g card that is empty, so its not a mem issue I dont believe.
So I got cut off. ::) Like 4 times and redo. Ugh

Anyways, I got that over with, so future vids can concentrate on running aspects, not the build and parts if im only limited to under 10 min or whatever it is. lol  Ill figure it out when Im not so sleepy. ;)

Ok, gota git
