On a motor nameplate, the "Frame" designation indicates what?

Explanation:
The Frame designation on a motor nameplate tells you the motor’s physical size and mounting envelope. It corresponds to a standardized set of external dimensions, bolt patterns, and shaft interface used for mounting the motor and for matching it with other components like feet, couplings, and gearboxes. This information is essential for ensuring the replacement motor will fit the existing mounting and align with the shaft and mounting hardware. It is not about speed, material, or color.
