stacked stators and rotors PMA

[Bernd]

If you feel eddy currents, how did you noticed that ? Did you feel something like cogging
or something like a little stiff axis ?
I think there is something wrong with connecting the coils together to one phase.
Maybe one coil has a short current.
Normaly you shouldn't notice eddy currents or just a little bit if all is connected correctly .

First you should measure the voltage you get from one phase between the two connectors from one stator.
Like Andreas said you have to switch the beginning and end connectors of every second coil when
you connect them together to one stator. Example:
The end of the first coil you have to connect to the end of the second coil, the beginning of the second coil
you have to connect to the beginning of the third coil, the end of the third coil must be connected to the end
of the fourth coil...... and so on. You ever connect end to end and beginning to the next beginning.
This is the correct connecting if the number of coils and magnets is equal and if each coil is identically wiring.
If you haven't connect this way, you will get almost no voltage.

Grüße, keine Verzahnung. Der erste Stator und Rotor eingestellt war ich Spinnen von Hand und es frei gedreht. Als ich am nächsten Stator und Rotor aufgenommen, noch Spinnen von Hand die Drehzahl reduziert. Hinzugefügt dritten Stator und Rotor letzten, noch Spinnen von Hand, ohne Verzahnung, sondern Rotation sehr langsam. Ich muss den Draht-Verbindungen und der Output gemessen beenden. Da die Statoren in 3 Phasen verdrahtet sind es vielleicht die natürliche des gegnerischen Feld berührt oder reflektierte Impedanz, aber weiß es wirklich nicht. Ich muss es wissen mehr ich ein paar Tage. Genießen Sie den Tag.




Greetings, no cogging. The first stator and rotor set was I spinning by hand and it rotated freely. As I added the next stator and rotor, still spinning by hand the rotation speed decreased. Added the third stator and last rotor, still spinning by hand, no cogging but rotation very slow. I will have to finish the wire connections and measure output. Because the stators are wired in 3 phase it maybe the natural affect of the opposing fields or reflected impedance , but really do not know. I should know more I a few days. Enjoy the day.

Have you connected the coils into the stator the way i said before ? (beginning-beginning, end-end)

Hi, the coils in the stators are wired output to input in a 3 phase configuration.

Project Update:
After considerable deliberation I have decided that the current configuration used to place the stators between the rotors is not cost affective. The design does work, proven by the fabrication of two PMA’s, one 6 inch diameter and one 8 diameter. Material cost and labor is to great. I am redesigning the PMA case using more traditional methods. The new design will allow for easier stator placement and reduce fabrication time. I will post photos in the near future. Enjoy the day.

Hallo, sind die Spulen in den Statoren Ausgang zu Eingang verdrahtet in einem 3-Phasen-Konfiguration.

Project Update:
Nach erheblichen Überlegung habe ich beschlossen, dass die aktuelle Konfiguration auf die Statoren zwischen den Rotoren Ort ist nicht kosteneffektiv affektive verwendet. Das Design funktioniert, durch die Herstellung von zwei PMA, ein 6-Zoll-Durchmesser und einem 8 Durchmesser bewährt. Material Kosten und Arbeitskraft ist groß. Ich bin der Neugestaltung der PMA Fall mit traditionelleren Methoden. Das neue Design wird für eine einfachere Stator Platzierung zu ermöglichen und zu reduzieren Fertigungszeit. Ich werde Fotos in naher Zukunft veröffentlichen. Genießen Sie den Tag.

Grüße, begann neue PMA Fall. Ich bin mit Fiberglas 3 / 8 Stangen und Stellringe auf die Statoren Position. Brauchen Sie Ideen für explosionsgeschützte elektrische Anschlüsse Wetter. Kommentare willkommen.

Greetings, started new PMA case. I am using fiberglass 3/8 rods and shaft collars to position the stators. Need ideas to weather proof electrical terminals. Comments welcome.

Hi, the coils in the stators are wired output to input in a 3 phase configuration.

Hmm... there seem to be some misunderstanding.
What you said sounds to me if you have made each Stator in 3 Phase design.
The number of coils of your stator and the number of magnets of the magnet rotor plate are equal.
If so there is no chance to make each stator to a three phase stator.
So i think each stator plate is one phase ?
If i'am right then what you said about connecting into the stator ( output of a coil to the next coil input) is wrong.
if one stator is one phase, then you have to connect the coils the way i showed before.

Hi, sorry for the confusion, I have been working on many vertical PMA,s. I confuse myself at times.

I am making a new PMA. It will have 4 rotors and three stators. The rotors have 16 magnets, 1” x ¾” N45 cylinders. The stator coils are one in hand 18 AWG with 100 turns. The stators are 3 phase configuration with 4 coils each phase and when they are all wired together they form a 3 phase with 12 coils per phase. I am hope this configuration will produce a charging voltage at a much lower RPM. I am a few weeks away before I can do any testing. Comments welcome and enjoy the day.



Hallo, sorry für die Verwirrung, habe ich mich auf viele vertikale PMA, s. gearbeitet Ich verwirren mich manchmal.

Ich mache eine neue PMA. Es werden 4 Rotoren und drei Statoren. Die Rotoren haben 16 Magnete, 1 "x ¾" N45 Zylindern. Die Statorspulen sind eins in der Hand 18 AWG mit 100 Windungen. Die Statoren sind 3-Phasen-Konfiguration mit 4 Spulen jeder Phase und wenn sie alle sind miteinander verdrahtet sie einen 3-Phase mit 12 Spulen pro Phase. Ich bin hoffe, dass diese Konfiguration wird eine Ladespannung bei einer viel niedrigeren RPM erzeugen. Ich bin ein paar Wochen weg, bevor ich irgendwelche Tests machen kann. Kommentare willkommen und genießen Sie den Tag.

Grüße, waren die Läden vor Ort nicht in der Lage, die benötigte Menge an Wellenbunde liefern, so verbrachte ich den Tag der Herstellung der Betrag, den ich brauchte. Ich bin sehr zufrieden mit den Ergebnissen. Ich habe die elektrischen Anschlüsse zu machen und ich sollte in ein paar Tagen getestet werden. Prost



Greetings, the local stores were unable to supply the required amount of shaft collars, so I spent the day fabricating the amount I needed. I am very happy with the results. I have to make the electrical connections and I should be testing in a few days. Cheers

Hey Govertical,

this stack looks great! Good luck testing the generator. Hopefully you get the expected results. I am realy looking forward to your experiments.

greetings Micha

Greetings, I completed the connections for a star 3 phase. When spinning by hand , there is a lot of drag. Measuring resistance between outputs the values are

L1 to L2 is 3.2 ohms
L1 to L3 is 6.0 ohms
L2 to L3 is 6.0 ohms

All these valves should be the same? Comments welcome.
I am glad that I took the time to add all the terminals.

This indicates to me that there is wiring problem. Proceeding to track down the problem. Enjoy the day.
