(...) 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)

(...) Didn't open a motor yet but with the description I would say that it is a thermistor (thermal resistive device). Better find a way to live it in place. (...) When I opened my controller I didn't saw (or remember seeing) such a device inside (...) (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)
