Hi, grretings from Belgrad, Serbia
Is it possible to use this old Röwa H0 ET02 motor in DCC, i think its power consumption is about 200mA unloaded on lab.power
I'm planning to install esu lok 4.0 54611 DCC, is there any chance to do it on this old motor ?
Mulțumiri.

Hello. Try to put the locomotive on track and measure the Amps absorbed at stall (mean to measure with power on, full throttle, and wheels blocked). Use a good protected power source to avoid any trouble. If it's in the range of decoder, is okay. Did you know the type of rotor? It is 3 pole or is 5 pole?
3 pole are not so good for digital, reacting strange at slow speed.I try long time ago with a Bachmann , and discarded immediately due to jack rabbit stile of running.
If you decided to not use this motor, better try to found one new one and replace it. E-bay and another places are full with replacements. Good luck. Electrical machine look very nice.

I can't determine motor specification (3 or 5 pole, power rating), i'm planning to use motor for dcc if it is possible.
If you look in table for Esu decoder, cont. maximum load is 1,1A ?

I'm gonna leave ceramic capacitor between motor poles, and discard choke coil ?

If it's 1.1Amp continuous, at peak should be at least 2.0 Amp. No idea regarding the choke or capacitor. For my side you should remove both, and just connect the wire from decoder. Not one of my locomotive have capacitor or choke from factory. My old TT materials have capacitor and that choke. Loksound, like all quality decoder, have built in thermal protection to prevent death by overload. My Tsunamy 750 are well protected in this way, soon as the sound board reach 75-80 C, turn of the power. Loco just sit on track and blink the lights till cool down.
