V5 Motor Failure Temperature

[andrew9635]

I am hoping to be able to write some code that will alert our drivers if any motors near an overheat. What would motor.temperature(percent) be equal to when the motors fail?

I would test this out myself but I am apprehensive of intentionally overheating equipment…

Thanks!

Not sure what the percentage would be (how is temperature returned as a percentage in vexcode???), but motors do start having additional current limits applied at 55C.

okay, thank you!! I’ll just run it in Celsius instead of percent

0% is 20C, 100% is 70C, and it’s a linear scale between them:

V5 Motor Temp in Percent?

The original conversion, the one that’s still in the VCS August version, is this. double temp_in_percent = (motor_temperature - 21.0) / (100 - 21.0) * 100; which was then limited to the range 0 to 100% so 0% was 21C and 100% was 100C, we knew these were not the real limits, it was really just a place holder until final numbers were determined. We updated in September to this. double temp_in_percent = (motor_temperature - 20) / 50 * 100; so 0% would be 20C and 100% would be 70C, this m…

I dont believe it is possible to intentionally overheat v5 motors due to the built in software stops, but you can read and print motor temp, as stated above.
