Merkle-Korff Brushless DC Planetary Gearmotors

Power and Control: Brushless DC Planetary Gearmotors

The 52P planetary gear reducer has higher power density and larger reduction capability in a compact package over standard parallel shaft reducers.

Merkle-Korff offers their Brushless DC gearmotors with either hall only feedback or a fully integrated control board, internal to the motor. The integral control is a fully digital control with the latest in micro-processor technology on board. The 52mm Planetary gearbox has high continuous and peak torque capability. It is also a very compact and low weight design.
