Powercroco aka borat, ralph okon, boho1,
You told Steve Neu the motor wasn't nearing saturation at 400 amperes. If it is not why is it going to be at least a 100C there based off your own data and the photos you have posted of damage including surpassing the curie temperature of the PM and class H insulation which would be well above 70C 😀 Were waiting for data and empirical photos that show it is not. Your fans don't extrapolate your posted data very well 🙈🙉🙊 70C is enuf to start 3d printing for Americans they can know that's 158 degrees F. and they cannot hold that motor in their hand! Its unholdable at 300 amperes.100C at 400 amperes is boiling water 212 degrees F. You know in reality though the motors see over 180C to demagnetize pm in a rotor. It stopped making additional torque and having adequate field for efficient commutation long before that. In this scenario one would think the residual inductance of the PM based off temp became increasingly poor losing real pull out torque.
