Hi some quick peeks at the pulse mag motor running, it will take three posts, just down load them and run them after eachother. it woull look good in the dark, there is no snubbing across the contacts, and they eventually burnt out, easy to fix.
No electronics running it just plain old DC.
there is only power aross one coil at any one time, peaks at 2.8amps, I vary the voltage, starts at 24 I did take it up to 60v, and I was also getting an output, but this is no load and I am only checking the 'motor' side of it at the moment, five mags on the rotor, four on the stator, 30mm long 30mm dia.
a devel to work on with spaners!

post one I am going to tyr it on one go

Hi guys
                 this as now progressed at first to micro sws, and now to a no contact infra red diode operation, running silent, I have been up to  620 RPM, but I have heating problems with the fets, but this is now being addressed, the aim is to get to 1,000 RPM, this is when the driven bolted on car alternator will kick in, I am still getting an output from the coils, this has been all been changed, I am getting all the BEMF out as well. It only has one rotor so I am only getting out half the power that I could. but it is good, it can be controlled easy, it is now down on the input current, only peaking a 3amps at 620RPM with about 55v input. however the 3 amps time the 55 volts will not give you the true power used, you have to take .7 of that 2.1a  then then times by 55 to give average power per second as in watts,  55 x 2.1 = 155watts it can get complicated because of the time on period, this is mechanically fixed, but as the speed increases the pulse time on is shorter, the voltage is higher but the current does not change much. however this all comes down to an .334 constant.

Sounds like a big challange, Brian! Power calculations are a pain sometimes, when it is not strait DC... ;) ;)

Hi Steve
                  yes it was a big challenge but it is done the concept has been proven in what I was doing, and there will be shortly a full prototype built shortly, what I have been working with was a test rig that was modified several times to prove each part of the process, this is the last part finding a good combination of Fets that I can use with out going to expensive, when you blow an $A12 one it is not all that bad, I only have four on the test rig. I have blown a few, there is a new type of coil configuration that I want to try for the separate alternator, if it work as I think it will, it will mean a big leap forward for this type of thing, and for the wind turbine generators. I have my own ideas on that, but one thing at a time. this unit will give home owners all the power that they need, and it will eventually end up in the EV cars, take out the 1.4ICE and replace it with this to generate power, this will give the EV's an extended range, or even unlimited, but the EV has to be the size of a mid range car, like a the Volt, or a mazda 6. the battery pack will only be as high as 96 or 108v, some of the converted cars over here are using between 6 to 8" DC motors, these are ideal, two fitted inline at the front and rear along the line of the rear drive  axils, and where a 4WD would be at the front. It will be interesting soon, and so far the car companies do not know what I am up to, but to have home power generation that is free is a dream almost there. Many just want to rip people off, but this is a serious attack it may take most power companies by surprise, bad luck they had a chance here to back my plasma conversion unit, and that is being brought back out, with a big powerful RF power supply.

hi I had magnetic interference as was to be expected, could have gone out further 4" would have solved the problem
 so made cam used industrial roller plunger micros, all good now, new 600w dissipation Fets fitted, and I have cracked the magic over unity, had a run of  COP 19. and at just over 500 rpm.
so it can be done. This is only a test rig with only one rotor, with two rotor it would be twice the current. However I do no care.  I am on track to build a fully engineered unit, output expected of over 15kW and all free power.

Thats very impressive Aussepom!
Hope one day you enlight us on how to achieve COP 19!!!!
 
Congratulations!

Nice to hear! Is this going to be a private or public source project :P

Hi
          private, I would not have got this far with out help, that was only money help,  now a large investor is interested but there are a few thing that I have done during the project that could be shared, or point you in the right direction.  and Steve it could go higher to  COP 32 at around 700 RPM but I have to watch the power dissipation on the fets
