I have a nice regulator of ds of 35ohm. now the inside is getting a bit black (as can be seen in the picture) my question is, how exactly does this happen?

Hello Robbin,

It seems no one has answered your question about why this happens.

It's a direct relation to the amount of use. If you use your controller a lot. You need to maintain it a bit more often.

Higher powered motors also create more current through the sweeper. If you like the fast stuff. You need to clean the wiper board more often.

Lastly. Magnets can create a lot of forward resistance to a car that should otherwise roll easy.

These three factors along with a few other things (binding gears, etc) create enough current to cause that black stuff.

I actively race with a few clubs. Sometimes there are several races per week. I have a Professor Motor controller that works like a charm. If I don't clean the board every six months. The brake starts to fail. I don't mind losing races. But a lack of maintance on my part would mean I would finish in last place every time.

Warm regards,
Ken
