I'm working on an axial flux alternator. As a safety feature, I would like to integrate temp sensors into the stator, as close as possible to where the magnets pass, so I can monitor internal temperature and trigger a shut down in case the alternator starts overheating during operation.
I have some 18B20 lying around, but I'm not sure if they will perform well inside a generator due to the presence of strong inductive forces, magnetic fields etc. Maybe it's just a question of having the right filters? The Alternator is slated to run at a steady 500-550 RPM, so EM noise should only occur in a distinct frequency range during normal operation.
The whole stator element, including sensors, will be pored in resin before operation. So, what ever I decide to do, once it's done, it's done
I'm open to any suggestions, ideas... Thanks!
