iwooten.comThe service factor rating is the amount of output the motor can develop without causing harm to the motor. If a 5 HP motor has a service factor of 1.15 the motor can produce an output of 5.75 HP without harming the motor. The service factor could be seen as a safety measure which would allow the motor to produce extra power if it was needed.
