  • NEMA insulation classes for motors Drives and Automation

    For example, an 80°C rise is often referred to as a 'Class B', as 80°C is the maximum allowable temperature rise for a 1.0 S.F. motor with Class B insulation and a 40°C ambient temperature. This practice means that a motor with Class F insulation and an 80°C rise is referred to as an 'F/B' motor.

  • Insulation Classes for Electric Motors ~ Learning

    Each insulation class has a margin allowed to compensate for the motor’s hot spot. The hot-spot is a point at the center of the motor’s windings where the temperature is higher. As can be seen from the above table, hot-spot over temperature allowance for A, B, F and H are respectively 5 °C, 10 °C, 10 °C and 15 °C
