Stator Temperatures & Cooling
Stator death is a common issue with the stock shunt regulator, and even simply due to bad batteries. As shere are many threads about troubleshooting electrical issues to determine if the stator has failed, if the battery is bad, and also replacing the regulator to help prevent stator failure, that's not the focus here.
I'm curious about stator temperatures and cooling.
I have a few questions:
1. At what temperature do stock and/or aftermarket stators tend to fail?
1a. What kind of insulation do the stator windings use?
2. What is the best way to get an idea of stator temperature considering it cannot be measured directly?
2a. What are some ways (and challenges) to setup these monitoring systems?
3. What is *your* (and ultimately a normal) estimated stator temperature (and/or proxy temperature that indicates approximate stator temperature) on average?
How has this been for your stator? (has it burned out at this range before?)
3a. At what temperature has your stator burned out?
4. What are ways to ensure good stator cooling? (other than using a series type regulator, and limiting electrical load - see other threads for details)
