Internal Gears have the teeth cut on the inside of the rim rather than the outside. When used with pinions, more teeth carry the load and it is distributed more evenly. This distribution of load decreases the pressure intensity and extends the life of the gear. The compact arrangement of an Internal Gear also means the center distance for a given velocity is shorter than that of an external gear.
