(...) I suppose I could try soldering wires to it and thereby put it between the DCC decoder output and the motor. Does it need to be thermally coupled to the motor though or is the heat of the current passing through it sufficient? Matt (26 years ago, 15-Mar-99, to lugnet.trains)

Hmmm, that's a jolly fine theory, I didn't know such a material existed. Maybe I need to go back and figure out a way to incorporate the disc into the modified motor[1]. It would be kind of embarassing if my motor fell out onto the track one day (...) (26 years ago, 15-Mar-99, to lugnet.trains)

I am sure it has a purpose and unless you know what it is you won't know whether it's safe to leave out or not. Manufacturing nowadays doesn't typically put stuff in that's not needed, need to save those pennies. My guesses: capacitator (but if this (...) (26 years ago, 15-Mar-99, to lugnet.trains)
