Wo bekomme ich einen Synchronmotor mit 230V für mein Klappzahlradio her?
Bei meinem Klappzahlwecker (mit Radio) ist gestern zum 2ten mal nach Jahren der Motor (wohl durch Staub an der Motorachse) stehen geblieben. Dabei ist wohl die Spule durchgebrannt. Nun finde ich im Internet einfach keinen baugleichen Ersatz. Ich hatte vor Jahren aus 2 Defekten Motoren ein ganzen gemacht. Bei einem war der Zahnradantrieb defekt, und beim andern die Spule. Ich habe damals auf dem mit dem funktionierendem Motor die Zahnradübersetzung aufgepresst. Ist ja genietet gewesen. Nun sind beide Spulen Schrott. Anbei 3 Fotos vom Uhrenradio, und 1 Foto vom Typenschild.

Old station clocks could have such a motor in it, microwaves have the ones for the turntables… if you pre-connect a small transformer that reduces the 220 volts to 6-12 volts, you could, I think, also use almost any other motor that is similarly built or with gear.
Even with riveted capsule motor housings, the rivets can be removed and their coil(s) can be rewound and stored in the engine winder.
Then you’ll only have some money at the specialist company.
Or it would have to be seen whether an electronically controlled pulse operation via a magnetic coil reciprocating piston is possible. could be realized for old Klapziffernuhren with minuted digits.
Hello, Gnurfy!
It doesn’t sound very good. 🙁 I am looking for (if possible) an identical engine, for this radio alarm, with a folding clock. I had written in my question where I could get a used and working motor. Let it be repaired (for so much money) is not worthwhile for me.
Unfortunately, you did not give us any picture of the original synchronous motor drive on the gearbox part of the folding number mechanism, but if necessary you also fit another SM in front of the chest with an adapter.
The simple SM motor itself runs in its spindle speed per minute at a sufficiently low counterload otherwise yes always synchronously with the AC voltage power frequency of, for example, 3000 rpm at 50 Hz, or 3600 rpm at 60 Hz alternating voltage.
Hello, Gnurfy!
I have still set photos of the drive in the appendix, and the engine I have built years ago.
I don’t want to have to look for the engine proposal on the web. I’ll give you that in the search.
Get some craftsmanship You will then certainly also base a small adapter plate for an only slightly different motor housing for attachment to the mechanism itself.
In the main program sequence switches of old washing machines, such motors were also installed for the movement drive.
Hello, Gurfy!
I had the picture of the drive first. Only I rebuilt the radio alarm just before I set the question. That’s why I photographed the tag in the hope that you can find on the Internet of this device where it is shown openly. The engines are always identical in such watches (almost).
