L = Large

M = Medium

S - Small

See the diagram and chart in this link below (both pages). You can then find the difference.

As you must be aware, the two digit or three digit number in a motor frame size, implies the vertical distance in millimeters from the base of the frame to the shaft centre. The following alphabet implies the length of the frame.

S stands for Small

M for Medium &

L for Long.
