Burning Temperature of Copper Winding of Motor.
I Have 3 motors 150watt 0.75Amp 220V in Copper and Aluminum and Copper clad aluminum.
I want to know the maximum internal temperature of these motors so that I can apply a Thermal protection sensor to avoid burning in the future.
Can anyone tell me the approximate range of temperature of burning of winding wire.
Someone suggested that I apply 45C temp sensor . I dont think she is right.

How hot it's allowed to get depends on what it's insulated with.
Here's a handy guide from MWS Wire Industries, and here's the source.
If there's any question at all, err on the safe side and choose 100C.
