(...) 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)

(...) Larry Pieniazek responded: (...) OK, here's my guess. It's a polymer thermal resistive protection device. Put it in circuit, and turn up the power...basically, no resistance. Now, with the power up, try to stop the wheels. This would increase (...) (26 years ago, 15-Mar-99, to lugnet.trains)

(...) Unless it's just for FCC in which case can rip it out ;) (...) I measured its resistance, it has none. So it's no capacitor. (...) Could be, although it's hard to see how. A conductor with 1/4" diameter could carry a few hundred amps! But (...) (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)
