About this document
Electric Motor Frame Size Guide by salazarafael is a document available to read on EtoBox.
The document discusses the evolution of electric motor frame sizes over time, including: 1) Three generations of frame sizes - original, U frames from 1952, and current T frames from 1964. New frames allowed more horsepower in smaller sizes. 2) Improvements in insulation enabled higher operating temperatures, further increasing possible horsepower. 3) Reference tables show horsepower and frame size standards for open and enclosed motors for each generation at common speeds.
