Class B Motor Insulation Rating at Philip Mayers blog

Class B Motor Insulation Rating. There are four insulation classes. 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. Nema motor insulation classes describes the ability of motor insulation in the windings to handle heat. Three classes of insulation are in common use. Anyone specifying or using electric motors should have a basic understanding how the insulation is related to temperature. This practice means that a motor with class f insulation and an 80°c rise is referred to as an 'f/b' motor. Motor with class b insulation and a 40°c ambient temperature. Temperature tolerance class f is. Motors rated as class “f/b” have a maximum winding temperature equal to that of insulation class f (155 degrees c), but an allowable temperature rise of insulation class b (80. Temperature tolerance class b is the most common insulation class used on most 60 cycle us motors. •nema identifies four insulation classes: Vfd controlled motors should have higher voltage ratings on the winding insulation, but that is not reflected in the class rating.
