@TK,


       Consider Skycollection's approach: Four bar magnets attached to a magnetic axle by the south pole covered with a brass sleeve. Combining his approach with my internal ceramic bearings would create a superior hybrid monopole rotor. He has a set of levitating bearings on the axel ends. Turning the axel along with the rotor slows his top end to about half the 50k I achieve with my internal bearings.


We reduce the inner axel to a stationary 1/8" brass rod. This mounts inside a sturdy PVC coupling to protect against a shattering. Next, the four bar magnets are stuck to a hollow 1/4"magnetic tube, and the race of precision ceramic bearings ride in between. This four magnet monopole rotor would be safe and approach Mach speeds as mine did.


A hole can easily be cut in one side of the coupling for the sensor coil, and another on the other side for the strobe window. The power coil can mount on the top while the pancake output coils rest on the bottem. A compact, safe high speed motor generator. The important advantage is that the RPM's will run over the Lenz delay threshold speed. This design eliminates your "end play" adjustment problem.

Yes, it's a good idea, but as I have tried to emphasize I don't have my precision lathe and milling machine here so I cannot work to the precision necessary to make a good highspeed machine. Thanks for the design idea though. I'm always interested in going faster, and I have my doubts about the validity of some of the high speeds that have been cited, as you know, since I've not seen calibrations or concurrently valid measurements, just an assumption that the driving frequency is equal to the rotation rate.


Meanwhile, back to the MHOP:

The neon you see in what I've shown so far is connected between the mosfet Drain and the Source. This clearly puts the 250 volt inductive spike through the neon back to ground. But... the neon also flashes just as well if it is connected to the Drain and the _positive_ pole of the battery. The spike is a lot more "positive" than the positive battery voltage! (This can be seen as having the neon "across the coil" too.) So clearly, again, the spike energy is going back into the battery when the neon fires in this configuration.

This whole setup seems a lot more controllable and "rational" than the standard Bedini setup, and it clearly produces the same kind of sharp inductive spikes and ringdown. And it's easy to put the spike back into the battery thru the neon, or less spectacularly through a diode. And if you don't want or need the Strobe LED and just want an indicator of firing, then you don't need anything downstream of the op-amp: you can just ditch the 4017 decade counter and the 555 pulse narrower. You still have to have a heavy transistor for the switching element but you can now use a mosfet instead of the lossy 2n3055! The IRFP360 that I am using stays cold, the coil stays cool... but the 1/4 inch bolt that I can use for a core heats up a little bit. But the motor actually runs better and makes prettier ringdowns without the core! You still get the huge spikes because of the clean switching of the mosfet. The op-amp acts almost like a mosfet gate driver, in that it delivers a clean pulse with good current, to fill the mosfet's gate capacitance quickly, and it turns off quickly too.

@Tk,


       Milling a center groove inside a long threadless square nut would allow us to seat one centered ceramic bearing, and eliminate precessional axel torque entirely. This is how I ran my protoype in the end. We can seat the bar magnets into the perpendicular surfaces of the nut then cover them with a sleeve, and use non-magnetic metal.


       We see Magnetman currently selling his alleged overunity generator on his new Free Energy thread right now, despite his sloppy measurments, the Hattem magnetic cogging device shown by MindFreer, and demonstrated again by Igor "Mopozco" show that COP'S>1 may be possible. A magnet core output coil in the base of this kind of generator has the potential to perhaps deliver extra power output.

@synchro: yes, being able to do things like milling slots in long nuts etc is nice and I'd be doing it if I had my Sherline tools here... but I don't. I am not into the frustration involved in trying to make something with a drill press and files that will spin stably at hundreds of thousands of RPM.

You should turn up your skepticism level a bit, I think.

Note: For the 555 pulse shortener, please change the 0.1 uF tantalum cap to a 1.0 uF tantalum, and make sure to use a 10k ten-turn pot. This makes the strobe LED brighter and gives more adjustability of its pulse width.


Meanwhile... no starting spin necessary:
