Electric Motor Safety Factor at Stephanie Barden blog

Electric Motor Safety Factor. The nema (national electrical manufacturers association) standard service factor for totally enclosed motors is 1.0. Basic isolation (or insulation) protects against high voltage as long as the insulation or isolation barrier remains intact. Safety standards such as iec. Motor service factor (sf) is the percentage of overloading the motor can handle for short periods when operating. Service factor is a multiplier that indicates how much a motor can be overloaded under ideal ambient conditions. Most documentation and motor selection guides state that engineers should choose a safety factor of around 1.5 to 2.25. This is practical as it gives you some ‘fudge’ in estimating horsepower needs and actual running horsepower requirements. To most it seems quite simple; Motor “service factor” is probably the most misunderstood value on a motor nameplate. The service factor (sf) of an ac motor is a measure of continuous overload capacity at which a motor can operate without overload or damage, provided. Motor service factor (sf) is the percentage of overloading the motor can handle for short periods when operating normally within the correct voltage tolerances. If it is a 1.0 you can run a motor to 100% load, if it is 1.15, then it can be.
