Series for compressed air motors with torque which can be theoretically output in a varied manner and a method for producing the individual compressed air motors of said series

A series of gear motors for differing output volumes, comprising:

• a series of at least two individual gear motors;
• each of said individual gear motors having a housing with at least two intermeshing displacing elements including a first displacing element and a second displacing element in the form of gears located therein;
• each of said individual gear motors of said series comprise having substantially identical dimensions for the axial interval between the theoretical axes, and between the theoretical axes of rotation of said at least two intermeshing displacing elements and a substantially identical gearing width in the form of a substantially identical axial extension of the gearing elements;
• and
• each of said individual gear motors differing from each other at least as regards the size of the tip circle diameter of at least one of said first displacing element and said second displacing element.
