Standardized motor dimensions established by NEMA (National Electrical Manufacturers Association) are listed below. These dimensions apply to all base-mounted motors that carry a NEMA frame designation. While frame numbers are not intended to indicate electrical characteristics like horsepower, the motor’s physical size and horsepower do generally increase as frame numbers become higher.
Simply click on the frame number to view motor dimensions.
