I'm thinking that it might be important to monitor armature temps in the brush area for brushed dc motors. Does anyone have any ideas on how to do this? I'm wondering if there's a non-contact sensor out there. Thoughts?
At this point I'm leaning towards a thermistor mounted on a brush holder; I couldn't find any cheap IR sensors. If you have any info I would appreciate it; some sort of readout is a necessity.
