Service Factor Engineering ToolBox

The service factor SF is a measure of periodically overload capacity at which a motor can operate without damage. The NEMA (National Electrical Manufacturers Association) standard service factor for totally enclosed motors is 1.0.. A motor operating continuously at a service factor greater than 1 will have a reduced life expectancy compared to operating at at its rated nameplate horsepower.

Motor Protection Communication for Critical Loads Eaton

A motor protection relay is used to measure or calculate the motor thermal condition. When the motor protection relay determines that the motor temperature is beyond design limitations, it signals a power component to de-energize the motor. To protect a motor from overheating we must use a motor protection relay. A common term for a motor protection relay is called an overload, which today is

Power Monitoring for Process Control NK Technologies

Power Monitoring for Process Control In applications where a load is not constant or the motor is over sized, the power factor improves as the load increases. The current draw of a standard squirrel cage motor does not rise in proportion to the wattage until the load is around half of the nameplate ratings. Consequently monitoring current only will not be as accurate as sampling power use
