Abb Motor Frame Size Chart. Most electric motors are built to an industry standard, either us or european. This increase in temperature capability made it possible to pack more horsepower in this case, each frame size designates a particular shaft height, shaft diameter, and face or base mounting hole pattern. Frame l449t is not included in this chart.
Motor fram size is very important mechanical data;
The stator frame is a rigid steel structure that has been designed to withstand vibrations induced by the driven equipment.

There are many motors of the same horsepower built in different. However, as a frame number becomes higher, so in general does the physical size of the motor and the horsepower. Located in ningbo city, an open seaport of china, we are one of the main manufacturer specialized in the manufacture of small & medium size electrical machinery in china. Frame numbers are not intended to indicate electrical characteristics such as horsepower.
