Brushless DC Planetary Gearmotors
Merkle-Korff offers our 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.
