Motor temperature measurement
Motor temperature measurement
(OP)
Does anyone know a way to measure the armature temperature of a PM DC motor without having to stop the motor? Reading the resistance between two leads requires the motor to be momentarily stopped which I have to avoid. I've been experimenting with thermocouple&thermistors and a Mercotac slip ring but it hasn't produced accurate results and is a bit of a challenge to setup.

I have tried to use an IR sensor but did not have good success. The surfaces of the armature that I am able to see have too low of an emissivity.
I looked into the wireless system a bit, and it looks promising. I've never used one before, so any additional information that you think I should know would be appreciated. The smallest motor is 0.01 hp so a circuit would have to be quite small (less than 1 in^2).

Would something like this be adaptable to your application?
