Bowman Permanent Magnet Motor Self Powered

[russwr]

1950 engineer built table model of free running magnets motor.  2 large discs with 90 degree rod alnico magnets. The discs were in line , but turning opposite directions. The back 2 sides were in bearings going to 2 gears in 2 : 1 ratio. Separate adjustable magnet in front was for starting, then locked down. North + South poles caused attraction + interference .

Gears are expensive, so I devised a method to make any gear ratio cheaply. Get thin rubber cogged appliance belts approximate size. Cut belt in half. Get plastic disc trimmed so as slightly larger than circumference. Put disc spinning in drill press. File down disc  outer edge. Stop. Keep rechecking rubber over circumference. When the 2 ends meet, remove disc and super glue the belt to discs.  The gears need the teeth counted before hand on straight belt so as can get the required 2:1 ratio. Oilite bronze bushings can be used or bearing blocks mounted on wooden board. The two horizontal non magnetic brass shafts require nuts and dual lock washers.  Surplus Neodymium rod magnets are on Ebay from China any size. My idea was to mount wire induction coils around outer edge of discs for 24 hour permanent night lights at low voltage. See data on Internet about the original Bowman Motor.

This paper may also be useful for some members (educational).  Not specifically deals with the Bowman motor though, sorry Russ.

Looks somewhat familiar, but with a novel experiment discussed in the paper.
Thanks, Brad!

Here is their conclusion:

4 Conclusion
The findings of the experiment indicate that the optimal configuration for the placement of magnets on the rotor is one that has a V-Gate angle of five degrees and a base dis- tance of twenty-four millimeters. This configuration yields the best results. Directly in the middle of the magnet arrangement pattern for the rotor is where the magnets on the stator are arranged in such a way that they face each other directly. Because of the way the magnetic configuration is set up, it can generate a rotor spin of 146 revolutions per minute. According to the calculations, the value of the mechanical power was 7.52 Watts, and the electrical power that was required to turn on the generator system was 8.24 Watts; as a result, 15.76 Watts of power were required to drive the system. Ac- cording to the results of the tests, the power demand can be satisfied with the 20,50 Watts of electricity that were generated.

Brad, have you found a way to increase the output power?

Does your device look like this, with TWO rotating disks?

Thanks again

Hi Steve

No, my design is unlike that.
My motor does not require any electrical input. 

I will be starting a thread shortly, in regards to distorting magnetic fields to make them work for us.

Another gate device like the hojo motors I worked on was the David LaPont device. The issue when trying to run them in a circle is that they became balanced. I was working on one which showed promise that was unbalanced but life got in the way. https://www.youtube.com/watch?v=hxg6gZRElW0

Thanks for doing this.  I see others are throwing guesses, so please entertain my guess.

I propose (possibly) The system uses the same torque plate design, with gear cogs on the main rotor.  Stationary magnets are secured to attract the inside of the torque plate like the original design, but the outside coil is now replaced with identical permanent magnets on  outside gears.  The main rotor's splines are the timing mechanism which time the outside magnets approach and exit, thus taking the place of the coil being turned on and off.

the the same 1+1=3 occurs, but now using only PM's and distance instead of a coil. 

I look forward to the revealing!

What could be seen as the torque plate, is now stationary, and where the magnets move.

Judging from the gear image you posted and this info, reminds me of this design attached

Yes, some of us tried that design many years ago, and couldn't get it to work.
Oddly enough, the 1+1=3 thing occurs, which is what led me to the torque plate motor design, that was based around that effect.

Nice, I always thought that design may benefit from a 3rd wheel on the opposite side attracting in while the other end wheel is trying to escape. Thinking possibly the extra force from the attraction may give it enough oomph to get past the valley of death.

Following your Gear + Video of the monopole, I can't help but to notice there is a slot in your gear that would fit a speaker magnet. So the side holes are for metal bolts or studs to create the monopoles like your video. So we have 2 of these gears with a stationary torque plate between.

Getting close?

Well there is no doubt about it. you're a thinker.
