This document provides dimensional reference drawings for NEMA and IEC standard electric motor frames and mounting flanges. It includes dimensions for frame sizes 143T to 588/9T, as well as dimensions for C, B5, D, and B14 flange types. Key dimensions such as shaft extension, mounting hole patterns, and terminal box locations are specified. Notes indicate that dimensions are specific to WEG W22 series general purpose motors and that the drawings are for reference only, not representative of all frame sizes.
