Hi all,

I was browsing the forum history and wanted to reply on some really old topics, but that wasnt allowed so here is a new topic. I am finally fed up with the noise my transfer table makes. To fix this the cheapest/simpelest way possible I thought of converting it to DC. Up to now I havent been able to find any wiring schematics on this so the questions is: is it possible at all?

I have some old laptop power supply modules with various output voltages lying around which I think would be perfect for the job.

If it isnt possible to feed the transfer table with DC (without major works that is) what other possibilities are there to quiet down the table?

PS: I remember an old quote on this forum, telling me to use it as a boat anchor, that is not really what I have in mind.

In the old topic it is said a part of the noise originates from the fact that the transfer table is driven by a half wave signal. I was wondering whether that half wave signal could be replaced by a DC voltage.

I agree that this wont't fully fix the noise issues but it might make the noise more bearable.

The ideal solution would be to exchange the motor for an sb-modelbau motor, but I would like to try a cheaper solution first. Maybe a schematic of the current implementation would already help too.

I have a k84 decoder lying around. If I would digitize the transfer table, would it be less noisier, or more noisy?

Hi Bert,

I have been running my transfer table with 12V DC for the last 6 months with no problems. It is a little quieter on the DC.

My 7294 motor burnt as well.
Any progress with successful replacement?

Hi
I have a 7294 transfer table with its overhead option.
I don't use it mostly because it is very noisy and incompatible with real medelling with sound, etc.
To be fair, the other reason is I focus on steam activity.
Of course the original Märklin motor can be powered with DC voltage to reduce noise. The speed must be adjusted for an exact positioning in front of access tracks.
Of course we all know about the SB Modellbau upgrade but HURRY because it is being phased out.
According to Stummi Forum user's the noise difference is very impressive.

Also, when replacing the motor, pay attention to the polarity and rotation direction otherwise protection diodes won't work correctly: they normally stop the motor when the bridge has reached one extremity.
Cheers

Can the 72941 transfer table be operated by the CS3? If so, what is the wiring?

I replaced the dead motor with a $3 12-24V DC motor from Amazon. Needed a little tweaking on inside to fit, but works fine with original control switch and 16vac power supply (and now have 4 spare motors :-). Not worth $50+ replacement as I rarely move it. The control box creates dc like power, so ac or dc motor both work.
