The service factor is a rating that indicates how much
a motor can be safely over-loaded. For instance, a motor that has an
SF of 1.15 can be safely overloaded by 15%. That is, if the motor is
rated for 1 hp, it can actually carry 1.15 hp safely. To determine the
overload capability of a motor, multiply the rated horsepower by the
service factor. The motor is capable of being overloaded because it's
designed with ways of dissipating large amounts of heat. |
