NEMA Electric Motor Dimensions

The National Electrical Manufacturers Association (NEMA) was established in 1926 and published standards for electric motors. NEMA frame size numbers provide manufacturers and users with key information about different electric motor dimensions. Motor frame sizes with the letter "T" means that the frame has been standardized across manufacturers to specific specifications such as horsepower, speed, and certain key dimensions such as shaft diameter, height, length and mounting base dimensions.
