Your advantages

High power density
thanks to high overload capacity, high torsional and tilting rigidity and freedom from mechanical play

Extreme precision
due to very high positioning accuracy and fast response time

Great versatility
thanks to integration in the modular system, which opens up countless combination options.

Any gear unit-motor combination from the modular design

Extreme precision with high acceleration torques - these are the outstanding properties of the ZN... servo cycloidal geared motors. . With their performance data, they are unique - regardless of torque, stiffness or weight.

The gearmotor is lubricated for life ex works, ready for installation and available in up to twelve sizes. The properties of the servo gear unit are particularly noteworthy: it impresses with its freedom from mechanical clearance, high torsional and tilting rigidity and outstanding overload capacity. This means that even demanding tasks, such as precise positioning or fast movement of heavy loads, can be completed with reliable repeat accuracy.

Any gear unit-motor combination from a modular design

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 servo gearmotor 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.
