Below is a unit I built some time ago, it maybe of some interest, I called it my jump jack motor generator.

Sorry for the late replies on this.
Hi Topher
It’s a Free energy device I built back in 1978.
It has 2 3-phase generators that keep’s the run batteries charged.
It also charges 2 batteries for any use.
Could never fully test it as it was very loud and it kept smashing its self into bits.
Hi rgbargee
The piston where not sprung.
Hi tropes
Very nice just been watching your videos.
This was the last diagram I did on this.

Looks interesting but why the 1,5v battery i understand the need for the 1.5 volts just not the battery.

The motor prior to this one used smaller neo magnets and a resistor from the 12V source. When I built this one I increased the size of the magnets and went to a 24V source. I found I was frying the NPN transistor (TIP102 darlington pair) which is used as a switch. In order to isolate the problem I wired the LED separately as well as the 12V circuit and the 24V circuit. I found the problem to be the BEMF to the transitor when the capacitor was not connected. Since I had the separate source for the LED and the separate switch in place I left them there.
BTW, since I changed to a directional winding of the coil (rather than back and forth winding) I am able to run the motor trouble-free without removing the BEMF plus the R.P.M. has increased. I believe it is very important to match the coil to the magnets ( wire gauge, core size and material, wiring method.)

Just when I thought I was so smart to engineer a unique way of transmitting reciprocal motion to rotary I find the Rootes company engineers were way ahead of me.

Welcome Tropes!
Excellent work, have you thought of using the mechanical motion to turn a generator?

Yes I have but I have found that I am able to generate a pulsing DC current by wrapping a coil aroun each piston much like one of those "jerk-off" flashlights. Depending on the direction of the wire I get some "free" voltage. I am presently rebuilding the motor but will keep you informed.

Direction does not matter if you use a FWBR and a capacitor will
smooth out the DC as well... FWBR is "Full Wave Bridge Rectfier"
for those who may not know. I LOL'ed @ your flashlight name :D

Hi Rob
That's what I thought but there seems to be a current induced by the main coil which either slows down or speeds up the magnetic pistons as they pass through the coils around them. The direction of the wrapped wire seemed to make a difference to the RPM.
I will continue to experiment as soon as I put the motor back together.

Hey Teep,
I can't believe your diagram! Just this evening I posted a loop for coils and BEMF, but I'd been thinking of putting them around a hollow core and running a neo magnet through them to generate voltage off coils staggered through it. I wanted to use the BEMF to drive the coils instead of a battery but the similarity is shocking. Of course you beat me by a few decades!
Thanks,

Hi 'tropes',
What kind of torque does this engine have? Or to put it another way, can it be stopped with just small finger pressure? |

Torque is not so easy to measure but suffice it to say that you cannot stop the output shaft with small finger pressure. Two 1.5" neo magnets are attracted to each other and to the iron core between them. The coil is then energized and the magnets are repelled with an equal force. As more coils are added as in the 5 coil motor I wish to construct, the torque will increase.

Finally built a new crankshaft and two new pistons. I consider this the "Simple School Girl" version with one coil and two permanent magnets.I haven't been able to upload to YouTube yet but here it is on my site: http://www.theowlnest.com/HPIM1472.MPG

I think you are right re: the direction of the magnets' movement does not matter but the direction of the coil wire must be the same on both sides in order to connect the two coils in series. I am not sure if the coils should be wound the same as the center pulsing coil. The image is for discussion and your inpute would be appreciated.

I am using the switch for the LED side of the photointerrupter as the On- off switch for the motor. The LED is powered by a 1.5V battery.
I have 1.5 volts available from the capacitor but only while the motor is running. So, how do I replace the battery with the current from the cap. Any ideas?

hi Tropes,
finally i found yah U-tube page.
been checking out yah Sotropa Motor...very cool and loud.
dont understand a thing tho(haha)...but its oke.
cant u use like a crankshaft or modify 1 from a car/bike and so on...nothing is impossible :))
if u dont try it u never know...always keep an open mind...once u close it...well ur done by then.
Peace! |

I'm sure you understand that the energized coil repels the magnets and the magnets attract each other. The rest is just timing; same as all electric motors including yours.
As for using an existing crankshaft, no one makes a crank that has two pistons attached that meet together.
The loudness is just machining and balancing.
Peace be with you!

Hi tropes Daftman did do a diagram for you somewhere on his computer but I cannot find it yet will post when I find it.
But you will need 270-ohm 1/2-watt resistor. (Resistor color-code is: Red, Violet, Brown, Gold.)
Maybe this one will help for now?

I replaced the 1.5V battery with 1.5V that I am taking from the 12V battery by using a 270 ohm resister.
I am still using the switch for the LED side of the photointerrupter as the On- off switch for the motor. The LED is still powered by 1.5 volts.
I still have 1.5 volts available from the capacitor but only while the motor is running. So, how do I replace the 1.5 volts with the current from the cap. Any ideas?

What I am saying is that it makes no difference which battery source I use to get the 1.5 volts to light the LED. What I would like to do is use the capacitor as the source but the cap has no voltage unless the motor is running. The voltage bleeds off when the motor stops because of the resistors used to reduce the voltage to 1.5V.
