Hi there

I have started in GBC not a long time ago but I bought a train regulator, wires and 5 medium motors. When I all plug them on the train regulator base it shut down after 30sec. To many voltage probably? How many motors can I put on a train regulator or what can I do to power my 5 motors? (except batteries)

Thanks

It does sound like the overcurrent protection is kicking in.

You can't really say "One train regulator can power this many motors" because the current draw for a DC motor is dependent on its load. Here's a video of one battery box (with similar current protection as a train regulator, about 0.8A) running 18 motors and 2 pairs of lights. https://www.youtube.com/watch?v=ztCMlcVzD1A

But there was no load on those motors other than internal friction. Fully loaded, one or two M motors will draw enough current to overload a regulator.

Are you plugging in just the motors? Or are they driving GBC modules at the same time? I would expect one controller to have no problems with 5 M motors if the modules were running smoothly. If you take the motors out, can you rotate the axle with your fingers? It might be that you have some extra friction in your modules that you can eliminate to help.

I can't add much to what the Captain said. On GBC displays we typically run two to four GBC modules per controller. The limit usually isn't the controller, though. The limit is usually which modules can run at the same speed (and direction!), and how far the wires reach. Running 5 GBCs is possible if, as Captainowie said, the modules run smoothly.

I think the motor control ic in the train regulator is overheating and therefor shuting down. The only thing you can do about this is checking if your modules have got to much friction or to solder a stronger ic in that can handle more current. But that involves opening the controller and moding it. im not shure if you wanna do this
