While during testing for inwheel motor performance, how to make the temperature of air-cool motor remains under limit?

I have to test a axial motor prototype, while during performance measurement, I do not want the motor to exceed temperature which in turn can cause demagnetization in motor, which can ultimately...

For electric motors like axial motor, when we do modal analysis, to which operating frequency should we compare natural frequency?

Should I compare the natural frequency to RPM of motor? or is it related to cogging torque? How do I know if my motor remains stable & won't vibrate at natural frequencies?

For Modal analysis in ANSYS, How to determine the Operating/external frequency of axial flux motor /inwheel motors to avoid resonance?

I am working on modal analysis, there I am getting my first mode at around 800Hz for rotor, I am bit confused to which external frequency should I compare this natural frequency, while max...

How to add variable temperature in ansys APDL, while in ansys there is option of constant temp, existing table & new table?

I want to enter my temperature as a function of radius as T(r,Θ) = T0 * (r/r0 ) * cosΘ. where theta is 0 degrees, r0 is outer radius, T0 is outer temperature. my question is how to build a...
