Is this the first selfrunning overunity motor w/o batteries ? Mike?s motor

[Peterae]

Something that is also interesting about this picture is if you look at the Power terminals on the breadboard there are 2 wires 1 red and other black going under the board as if to a battery.But this circuit layout was only meant to prove it worked with a battery anyway.He later added the ssr circuit.

this is the pic of mikes motor i have

  it looks like the washers are a part of a wire reel or something he
  has used to hold his magnets
  i dont think there is any need to worry about this
  may be a large washer acting as a flywheel would make sence
  a fly wheel would help the rotor spin evenly

  thanks

Hi Warren,

The photo of mikes motor you just posted seems to have a couple of
donut magnets on the shaft as a flywheel with disks in-between.
It looks like a cylinder homopolar type of setup ?
without being connected though.

ok, maybe if you read this, instead of the output being used for 'work' it gets fed back to running the motor...........


A compulsator is the short name for a compensated pulsed alternator, a form of power supply. As the name suggests, it is an alternator that is "compensated" (see below) to make it better at delivering pulses of electrical energy than a normal alternator.

The principle is very similar to an alternator, except that the rotor is usually kept spinning by its inertia (having been "spun up" by an external motor, or the compulsator itself having been used in reverse as an AC motor) and the small matter of the "compensation". The compulsator is used like a capacitor, to gather energy from a low-power source and store it, then generate a high-power output for a short period.

The windings of a compulsator are different from those of a normal alternator in that they are designed for minimal inductance. This allows the current in the windings to change very rapidly, which is why this "compensation" makes it better at delivering pulses.

The kinetic energy of a rotating object depends on the mass of the object, the shape of the object, and the square of the speed of rotation. Therefore, compulsators tend to have very light rotors that spin very fast in order to store the most energy in the available mass, and because too much mass in the rotor causes problems with the magnitude of centripetal force required to prevent the rotor from flying apart.

Compulsators are popular choices for high-end railgun power supplies. One possibility being considered is to build an electric tank that uses a conventional diesel engine for propulsion and to charge a compulsator. The compulsator would be used to power a railgun, and potentially other pulsed energy weapons (particularly electronic warfare systems); also, the compulsator could be used in non-pulsed mode to drive the tank with electric motors for limited periods as a kind of "quiet mode", which could be useful in urban combat.

OK I've gone back and done a re-examination of all the info and pics.

It appears that there is perhaps an error in what Mike told us, but my findings are not in agreement with Peter's.

Have a look at the attached pic. I've annotated it with references. It looks to me what Mike did when winding the coil-mass, was to solder all 3 wires together at one end before he started to wind. Then when he finished, the 3 wires were again separated, as evidenced by the residual solder that can be seen in the pic on two of the 3 wires on the left side (zoom in real well). The Gen+ wire looks twisted, but that is just remnants from when all 3 were twisted together.

If you look at the 3 wires to the right side, you can see that the Gen- wire is in fact the same size as the Main- wire, and that is a 28 AWG.

Mike told us the Trig and Gen wires were both 30 AWG, but that does not seem correct according to the picture.

I have analysed the motor and determined that the coil-mass dimensions are very close to:
w= 4.6"
h= 4.4"

so one complete loop ~ 18" or 1.5'

From this I have recalculated the Main inductance value. Using the voltage amplitude ratios from the sine scope shots, I then figured out the Trig and Gen inductances. They are very close, but now the Gen winding is with no. 28 wire, so its resistance is about half.

By analysing the D2 scope shot of Mike's, and extracting and analysing the audio from his video, I was able to determine that his motor is running at somewhere between 342 and 382 RPMs. I have chosen 345 for the rest of my analysis.

So, bottom line is there appear to be 3 windings, one of 30 AWG, and two of 28 AWG wire.

Hi Darren
Thanks for trying to see what im trying to understand,
The wires as you said look as if they have all been soldered, in this picture,  to me it looks like each wire is a twisted pair, but you may be right about them being twisted when wound, then un twisted.

The trouble is now i have no idea of how he got those resistances.
I start construction tommorow, and i need to work these dam coils out.


But the Gen wire on the left looks twice as thick as the gen wire on the right Oh well.

OK OK
I give up.
I am going to make your coil above but what i will do is make 2 sets of coils 240 turns each that way i can use the second coil to play around altering the resistances and will use 1 strand to double L2 to 473 turns.

Have you made your version yet or are you just trying to get the parameters at the moment.

Peter
