The MD adapter combines the advantages of a direct motor attachment with the benefits of an adapter attachment. Despite its enormous compactness, the MD adapter offers positive torque transmission as well as the option of simply replacing the CM3C servomotor.
The HN adapter provides a variety of different possible motor mounting dimensions for even more flexible motor mounting by the customer. Mounting is non-positive via a clamping coupling. The ZN.. cycloidal gear unit from SEW-EURODRIVE is optimised for operation on the servo inverters of the MOVI-C® modular automation system. The modular attachment via the MD and HN adapters complements the existing ZN... servo cycloidal gearmotors. CMP... in direct motor mounting.
