[lolonghauler]

are we talking 12v or 240v etc??

[jeffmolly1]

@lolonghauler that depends on the stator core used.Typically they are made for wind turbines and hydro applications.

[lolonghauler]

how much power does this out put?

[jeffmolly1]

@lolonghauler that depends on which stator and rotor used.

Hi jeff great videos I had a question or two. When you connect the stator core wires with the three phase jack wires you really don't need to connect it to the rectifier in the pma right, it's just cleaner? You could actually just take the rectifier out of the pma and just have the wires connected but they would be loose right? Once you have that rectifier out of the pma you can use it to change the three phase AC back into DC?

@VOODOO74W that is correct voodoo74w.

[turbineguy100]

whats the point of using 3 phase ac?

and what kind of alternator is that?

[BudsMoKing]

I got a little long winded there. My question is, if your running 3 phase instead of dc from the alternator, why not use the rectifier from the alternator instead of buying or building a new one? This setup is a cost saving measure anyway.

@OKMUNWURX A Perm Mag alt doesn't need current to generate the mag field, the mag field is "free" only needs something to rotate it. A regular alt feeds on dc to create a mag field so current can be generated and also needs to be rotated by another force but the mag field is "created" by current flow so, it presents more resistance to rotation and thus, the force needed to rotate increases noticeably as the electric load increases.

How can you say it does not matter how you connect the wires. Shouldn't one be pos, one neg, and one the ground.?

[snappy327]

i have to say i am happy to see a company showing the end user how to set these systems up without having to pay for consultation. for that reason alone would make buying from these guys more attractive. i have seen a couple videos on here from end users that refer back to this company with pure loyalty. I was poking around on their site and i didn't see the option to buy the rotor assembly. for someone like myself, i would like to buy all the parts separately and assemble them from scratch.

Hi Sir Very nice work, I just wonder how much rpm does it take to charge a 12v car battery using same car alternator stator and magnet you used. thanks for sharing your knowledge to everyone.... (suppose i have a 70amp 12v car alternator, what do you think would be the ideal speed ??? )

[TheDegree777]

How many rpms this pma make?

[OKMUNWURX]

Why use a PM rotor when the original will provide the magnetic field? The original allows voltage regulation : as output voltage rises, the dc feedback to rotor is reduced and so preventing further output increase ( a regulator unit is used; sometimes built in). With the PM rotor, output voltage will vary due to load and rpm.  The only reason I can see for using a PM rotor would be for 100% attention free operation....Is that the reason for using a PM rotor? please email me; much to discuss

[rusty2507]

Great videos Jeff. Excellent job of explaining several points I needed cleared up for next project. I've subscribed & am looking forward to viewing more ideas for renewable energy.

Thankyou

[meisterjager66]

The point is the cheaper wiring,less power drop

[nerfren01]

My question is how to make the alternator turn on and off and where it should be placed (if you can get wet) and nothing happens. Also if I can use like the wind away from home and when I would need to move all the electrical things in the house?

[ccowdog72]

I Really enjoyed these video's
