Merkle-Korff Brushless DC Gearmotors

Merkle-Korff offers 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 motor can be mounted not only to their most robust parallel shaft gear box that they manufacture (MK’s GF gearbox) but it can also be fitted to their new line of 52 mm planetary gear heads.

Our domestically based engineering team has the expertise to customize the software to meet the various demands and requirements of virtually any application. Our brushless DC gearmotors are currently being utilized in virtually every market we serve, including the commercial food equipment, pellet stove, satellite dish and pump markets. For those applications that require a higher degree of controllability or a higher efficiency solution to meet your green initiatives, the Merkle-Korff Brushless DC product is the perfect solution.
