NEMA frame sizes include designations that can help you learn more about the size and capability of practically any particular motor. For example, the letter T symbolizes that the frame size has been standardized by NEMA.
The important thing here is that it also means that everything from the dimensions, speed and horsepower are uniform for motors with the same frame size. This kind of information can help you make an informed decision when shopping for new motors.
So what does the information on a NEMA size chart mean? It tells you where a motor sits in terms of diameter, torque, and the typical speed, or the rate of RPMs.
