 | Houston,
1 Gleichstromgetriebemotor (max. 12V 3A) functions super with a Notebooknetzteil.
2 this Notebooknetzteile are present and the motor should itself according to into Steckdose gestecktem power adapter turn - The Netzteile are gegenpolig on the motor montiert.
If only 1 power adapter montiert is, functions the motor but are both Netzteile montiert then klickert only the each bagged power adapter instead of whom motor To turn.
I have of Elektr(on)ik hardly Idea, vlt. registered a manner Sicherung in the each bagged power adapter a "Kurzschluss".
this functions naturally:
power1 -> power adapter1 (+-) -> motor turn right
power1 -> power adapter1 (-+) -> motor turn left
power2 -> power adapter2 (+-) -> motor turn right
power2 -> power adapter2 (-+) -> motor turn left
however not working:
power1 -> power adapter1 (+-) ___ motor turn not  power adapter1 power only each second quiet "klick".
---------- -> power adapter2 (-+) /
and not:
---------- -> power adapter1 (+-) ___ motor turn not power adapter2 power only each second quiet "klick".
power2 -> power adapter2 (-+) /
self-evident are never zeitgleich both Netzteile bagged, It's all right only therefore by Einstecken the jeweiligen Netzteiles The Drehrichtung To to determine.
I need well one manner 12V 3A- Y-Bauteil, that once of A power comes B zumacht or once of B power comes A zumacht so I both Netzteile simply behind this Bauteil gegenteilig on whom motor poland can.
Hülfe, what kind of Bauteil need I or. How becomes something like called? |

| I faith i see unfortunately what you mean - therefore becomes my Test today Yes sooner a act of desperation.
If I then successful failed be would I gladly over again your obigen Circuit consecrate. |

ByteAttack | | into Plusleitung eachone fountain a Diode ought to wealthy, without very to know what really the target his should. |

| Mist, will be well to Do. not testing can, obs still simply by Dioden functions.
>> Plusleitung eachone fountain a Diode
If because then The despair naht, I will too these Mgl. debug!  |

ByteAttack | Why really two Stronquellen? will be not integrally schlau drauß???
alike - there's z.B. too Kippschalter 2polig One/from/One and the as Polumschalter using (left/from/right) |

Freier | well that The Netzgeräte a Thermosicherung (presumably) having, because You make always a Kurzschluß.
Nochmal The Netzgeräte/Gleichrichter in the principle:
@Marc: there sits presumably apiece of/ one to of/ one Steckdose, the whom motor only in a direction turn let must. 
@GDL: can you not for iF a Blackbox, possible with MOSFET, make? Stefan has Yes yet leave. |

| @Thomas: Thanks you understand I increasingly of it, I there do. ^^
there sits naturally nobody in a "Kippschalter" around the motor then To turn! 
I have a USB-Steckdosenleiste and can above 220V Schukodosen by Kommandozeile on- and turn off - this against happens by Webserver - the motor itself already quasi "per Handy" turn can only unfortunately only in 1 direction.  |

|
| | i don't know whether it helpful is, but I would self-evident z.B. simply with Conrad everything run down what for necessary is and it (naturally) too zusammenlöten - for such einmalige activities could such one Lötkolbenstarterset first of all suffice. ^^ |

Thomas
Freier | then nimm time this Prinzipbild:
carry your border with Conrad to with the erforderlichen Lastdaten.
The can The suitable MOSFET and Widerstände raussuchen or there's a finished Bausatz.
One Kurzschluß won't prevented, if both Netzteile at the same time active are! me falls on The speedy no Circuit one, except Relais.
to Info : [...] 
but How said: is Stefans or George Metier.
I coming to 40 years in 1 B 21 Bochumer street short with Transistoren in touch and having professional then with Hochspannungsanlagen and its Primärgeräten To do. for Lüster+clip gabs electrician. |

ByteAttack | i think too, the one with a Relais rather wegkommt. one needed too only a Stromquelle.
The problem will be, that if one 2 Gleichspannungsnetzteile Ausgangsseitig verpolt zueinander parallel toggles these itself mutual kurzschließen! even if only one with 230V keeps becomes.
with Dioden alone can itself on this trouble too so quick nothing Change.
Solution: I go time of it from, that You each einzelene Steckdose einzelnd chid can.
One Netzeil to Versorgung the Motors use, and the others one 2xUM-Relais as Polwendeschalter for motor operate. |

Freier | The problem is his Netbooknetzteil, that not as gaze Spannungsquelle to examine is.
here, there do you need at Löten not so softly-softly his, one suggestion with Conradteilen. DC-DC - Wandler and 5VDC Relais.

| understand I The drawing correctly., that hereon the following To see is:
+ 2 Netzteile
+ 2 5VDC Relais
+ 2 DC-DC Wandler
+ 1 motor
+ Lauter Klingeldraht
? |
|
| |
| |
| |
|
|
Thomas
Freier | Yes, where I at "Klingeldraht" consult let would. possibly, that it too Grundplatinen for Montage gives. important, that the DC/DC-Wandler whom Spannungsbereich abdeckt. already times the thrill of power adapter measured?
Leerlaufspannung 19VDC and under Motorlast 10VDC? |
