Electric Motor Insulation, (Read This First!)
Furthermore, if we encounter a motor with insulation class F and a temperature rise of B, denoted as F/B, it signifies a temperature rise of 80°C + 40°C, summing up to 120°C. Comparing this with the maximum allowable temperature of 145°C, the motor exhibits a surplus of 145°C – 120°C, equating to 25°C.

1. If a VFD is being used and the motor is not inverter duty should you consider a minimum class of insulation. and would it help? 2. We know there is Class B, F and H insulation classes available. We also know that <3200' elevation B should suffice in most cases. >3200' F is needed to get a B rise at altitude. >3200' H to get a F rise.
