What is an orbit motor and why do you need it?
Jun 19, 2024| Epicyclic gear motors are also called orbit motors, gear ring motors or gerotor motors. Unlike external gear motors, the orbit motor has very low oil leakage. The motor can produce large torques at very slow speeds (approximately 5 rpm).
Just like gear ring pumps, the rotor of the orbit motor has one tooth less than the stator. Because of the difference in teeth, enclosed chambers are formed within the orbit motor.
Epicyclic gear motors or orbit motors are available in two types: one has a central shaft and the other has a cardan shaft. Orbit motors with central shafts are widely used in hydraulic systems.
The orbit motor with a cardan shaft consists of cylindrical rolls in the set of gear wheels. It is only used for special applications (e.g. high pressures, very high efficiency and longer lifespan).
