Two Bedini Circuits on a Pulse Motor – 9 Mag & 4 Mag Rotors Both ~600 RPM
Watch two Bedini circuits power a pulse motor with a 9 magnet rotor and a 4 magnet rotor Celtic cross both hitting around 600 RPMs. I test dumping both collector spikes into one coil and share what actually happens on the bench.

What to watch for
- ▸Two Bedini circuits can run separate coils on one motor and keep both rotors near 600 RPM even with different magnet counts.
- ▸Dumping both collector spikes into one coil dropped RPM by about 100 instead of improving performance.
- ▸The circuits seem to help each other when each has its own load coil to dump into.
- ▸A 9 magnet rotor and 4 magnet Celtic cross rotor can reach nearly identical speeds on the same motor.
- ▸The second motor spins up fast once the first circuit is running and they interact.

I hooked up two separate Bedini circuits to the same pulse motor, one driving each coil. One side spins a 9 magnet rotor while the other runs a 4 magnet rotor in Celtic cross style. Both settle around 600 RPM and I test what happens when I dump both collector spikes into a single coil.
Key takeaways
- Two Bedini circuits can run separate coils on one motor and keep both rotors near 600 RPM even with different magnet counts.
- Dumping both collector spikes into one coil dropped RPM by about 100 instead of improving performance.
- The circuits seem to help each other when each has its own load coil to dump into.
- A 9 magnet rotor and 4 magnet Celtic cross rotor can reach nearly identical speeds on the same motor.
- The second motor spins up fast once the first circuit is running and they interact.
In this bench session I ran two Bedini circuits on a single pulse motor. One circuit powers a coil facing the 9 magnet rotor, the other drives a coil on the 4 magnet rotor. Both rotors hit roughly 600 RPM which surprised me given the different pole counts.
I measured 603 RPM on the 9 magnet side and 579 on the Celtic cross 4 magnet side. When I combined both collector dumps through diodes into one coil the speed dropped about 100 RPM, so I switched it back.
The takeaway seems to be that each circuit benefits from having its own load to dump into. Once both are running the second motor really picks up speed, climbing from around 523 to over 546 RPM quickly. They kind of help each other out.
Pretty cool to see a 9 magnet and 4 magnet rotor balancing out so close in speed on the same setup. More bench notes and exact observations are in the full video.

hello ladies and gentlemen welcome to the channel this is Papa Bale what we're looking at here is a nine magnet rotor pulse motor um being run by two bedini circuits one here with the lights down there one here and it's connected to this this coil on this motor and then we've got this one over here here it's connected to that coil on the same motor so this one's going now let's get attack rating on it 603 now let's get our attack on the other one this one's going pretty fast four magnet rotor Celtic cross stle about the same 579 now I just wanted to see you can dump the energy from both of the SG coils into one of the other motor coils and it will work better or just the same um as hooking it into another coil I think it actually works better here we can test that theory real quick be right back all right so now I have both of the collector dumps the bendini circuit uh collector circuits through the diode are both now connected to this one coil and so that's twice this twice the Spike let's see what the tackle meter says where I put it there it is oh no that's a little worse oh yeah about 100 less okay so we're going to put it back to way it waso it's good to have when you're using this circuit it hooked up to something else that runs I guess and then they kind of help each other the others the end of the circuit and then the start kind of help each other so yeah that's awesome look at that look at the second motor run dude it's like so fast that's awesome already up to 523 546 that's the that's the message right there a messenger has no important about 600 over here they're about equal which is we weird we got two coils running each one that's nine magnets and this is four magnets and they're body coil in RPMs go figure awesome well thank you very much ladies and gentlemen peace out have a good day please subscribe and hit me up on the Discord if you got an email from me peace out
