Pulse Motor ( no work required to remove rotor magnets from cores )

Hi groundloop, thanks for the circuit, im just using the electronic parts i have on hand and also my circuit i have tested on other motors and works well although if this motor works out ill probably try the circuit you posted with less parts. Yes im taking the flyback off with diodes as your circuit shows into cap bank or charging batteries or cap dump charger. just about ready to fire up coils and tune them to fire appropriately.
peace love light

[EDIT] Added a proposal (tested circuit) for your coil switch. This circuit will save you
          one transistor pr. switch. Also, the back emf generated voltage is channeled
          through a ultra fast switching diode and can be used to charge up batteries.
          If not used then the bemf output must be tied to ground to protect the NPN
          transistor.

Hi Groundloop,

May I tell you to swap the PNP transistor emitter and collector pins in your schematics?  Emitter should go up towards the positive battery voltage via the 24 Ohm resistor and collector should go down to common point of the 1 KOhm resistor and the base of the NPN.   Very good circuit by the way.

Thanks, Gyula

@gyulasun,

Yes, you are right.
I have updated the drawing.
I just redraw the circuit today by memory.
Sorry for the mistake.

@SkyWatcher123,

Looking forward to see your test results. I have an "old" Muller motor collecting dust
and I may fire that motor up again if you get good results.

Hi folks, just an update. i've hooked up 1 coil phase, still hooking up others, and it runs nicely although when driving coil with more voltage the rpm increase causes too much vibration. I'm hoping its only because the other magnets interacting with the cores are causing this and that when all 3 phases are operating it should be smooth and fast, right now with the 1 phase at 24V it has some pretty good torque and speed though obviously needs all 3 phases to function properly. The only thing I dont have for testing is an rpm meter, so any ideas on how to accurately measure rpm short of buying an expensive meter which is not an option due to funds. i do have an rc model tach., but it suffers interference from the ac light bulb frequencies. Anyway heres a pic of the motor setup.
