Design Power vs. Motor Power and Service Factor can be expressed as
PD = SF P (1)
where
PD = design power (hp, W)
SF =service factor
P = motor power (hp, W)
A 1 HP motor with a Service Factor - SF = 1.15 can operate at
PD = (1 hp) x 1.15
= 1.15 hp
without overheating or otherwise damaging the motor if rated voltage and frequency are supplied to the motor.
Insulation life and bearings life are reduced by the service factor load.
