Thankyou for the advice! I'll try to change it  but for now it's ok. I know it's not strong enougf . If i'll have to go to high rpm then i'll stop and try to put something  more serious. Also I followed your advice ; it spins better anti clockwise.

Thankyou romero for all the info you've been sharing with us!

Hi All,

I'm still testing but in my very sensitive machine, I do not find any Lenz reduction using a cap. in series with the coils and the
bridge, feeding a 68000uf cap with a 100 ohm load (50mA @ 5VDC) on the 68000 cap.  Anywhere between 2.5uf and 100uf series Capacatance, increments of 2.5uf, I find only a reduction in output along with and including an increase in Lenz/loading (lower RPM) on the rotor.  I could be wrong, but a load is a load is a load.  I will continue testing tomorrow but that is my initial findings. 

I have also discovered a strong interaction between the pulse width in the motor and the back EMF generated and fighting that pulse, which tends to vary the current with placement of the hall, not a change in the ratio, but a change in the current in the motor..  Poorly stated, but a problem.  Something else to juggle and get to stabilize with RPM........

Romero, what the heck are you looking for/adjusting in or out in your device with core/coil placement......that you have never told us.......help!

Did you short the DC side first? tune into a short circuit. Are you sure your coils are out of phase? this cannot work with in phase coils. Voltage over series cap into a short dc path and tuned is going to be perhaps well over 50 volts. If you get non of this something is badly messed up.

My experiment is under way, the same change in parallel and series capacitors, but not the slightest change in the output.

    Hi bolt

    Want your help, it is best to have an indicative description of the circuit schematic.

    Thank you very much!
