Planetary geared motor in various designs

Planetary geared motors are available up to 75kW and are used today in various areas with high torque requirements and compact designs. The modular planetary gearboxes consist of a sun, planet and internal gearing. The planetary gearboxes are available in different versions and with a wide range of accessories to meet the requirements in different working areas. As the planetary gearboxes operate in small spaces with high torques, their high power density results in a correspondingly high thermal load in the gearboxes. For this reason, the thermal performance must be checked when selecting a gearbox. Planetary gearboxes are primarily used in mobile machines and have become established in cranes, metal processing machines, construction machinery and wind turbines.
