Motor Insulation Class F Means. — motor insulation class specifies the maximum allowable temperature of the motor winding insulation to provide a life of 20,000 hours. A, b, f & h •temperature rise by resistance limits for low voltage, random wound. Modern insulation materials means class f insulation is commonly used for motor windings. this practice means that a motor with class f insulation and an 80°c rise is referred to as an 'f/b' motor. — use of class f or class h insulation can increase the service factor or the ability to withstand high ambient temperature conditions. operation of motors within the designed parameters of their insulation class can yield significantly increased reliability. — three classes of insulation are in common use (with 'f' being the most common): •nema identifies four insulation classes: temperature tolerance class f is the most common for international and 50 cycle motors. nema motor insulation classes describes the ability of motor insulation in the windings to handle heat.
