In addition to the issues jraef has mentioned, it is important to realize that unless specifically stated otherwise, motor nameplate data is based on sinewave power. As soon as you introduce VFD or pulse power to the motor, everything changes.
That's why it is important to always enter actual nameplate data into a VFD. The drive will factor those numbers based on numerous other considerations to properly thermally protect the motor. Even then, the protection is estimated, not measured. You may very well set up all the overloads, etc. properly but if the goon squad comes along and sets a large cardboard box tight against the fan intake on a TEFC motor, the motor may well burn up before the estimated protection realizes there is any problem. or what if the fan slips off the shaft, or the forktruck operator rams the fan shroud and.....you see the problem.
If you want real thermal protection, you want measured temp, not estimated. That requires thermistors in the motor windings (p leads in the junction box) or something else that actually measures temperature in the motor windings.
Inverter duty motors often have these switches with the resulting protection circuit. Sadly, in my now-ending career the P leads were often left disconnected and the better protection forfeited because many field people don't know what they are.
