System Solutions with Servo Gearmotors

System solutions with servo gearmotors: helical gear units, parallel shaft helical gear units, helical-bevel gear units and helical-worm gear units can be mounted on SEW-EURODRIVE’s synchronous servomotors DS, CM and CMP servomotors.

The /R option (reduction of circumferential backlash combined with high efficiency and high-endurance gearing) gives the gear units servo-typical characteristics, such as high positioning accuracy. With their wide range of options, the MOVIDRIVE® drive inverters provide you with the functional, scalable and intelligent systems you need.

The standard gear units of the 7 Series incorporate power and variety. The synchronous and asynchronous servomotors are characterized by precision, dynamic and torque in a compact design. The combination of these gear units and motors sets standards worldwide. SEW-EURODRIVE’s modular concept, which offers millions of combinations in the area of gearmotors, can now be used in the area of servomotors, providing you with all of the freedom that you need.

Helical-bevel servo gearmotors
Helical-bevel gear units from SEW-EURODRIVE provide a high degree of efficiency of over 95% in both torque directions and at all input speeds – performance designed to last. High-endurance gearing enables high-torque, wear-free operation long into the future. The remarkably high efficiency of our helical-bevel gearmotors makes them energy-savers. As they also have a long maintenance-free service life, they can be used in every application with AC asynchronous motors and synchronous servomotors.

Helical-worm servo gearmotors
Installation of angular gear units is particularly space-saving. The attenuation characteristics are a further bonus resulting from the simplicity of the mechanical design. As a result of longitudinal application of the force on the input shaft, the torque impulses are dampened. The noise level for this device is very low, even when a large amount of force is applied. This means that our helical-worm gearmotors can be used even for stage elevators.

Helical servo gearmotors
The variety of sizes allows almost all requirements to be met. For high output speeds, the RX57 to RX107 series of single-stage gear units offers compact, space-saving solutions. And applications where weight is an issue will benefit from our multi-stage gear units: Thanks to their die-cast aluminum design, the models R07, R17 and R27 are three particularly efficient lightweights – ideal as satellite drives and for use in light machine constructions.

Parallel shaft helical servo gearmotors
A standard drive that is not only favored because of its performance, but also for its structural properties. Typically found in conveyor and materials processing applications, the parallel shaft helical gearmotors from SEW-EURODRIVE can always be relied on to perform diverse drive tasks.

SPIROPLAN® servo gearmotors
SPIROPLAN® servo gearmotors with directly installed CMP synchronous servomotors are extremely efficient, quiet and, with a wide variety of different designs, offer the customer the greatest possible flexibility. The W37/W47 Spiroplan right-angle gear units enable high speeds at even the smallest reduction ratios and the wear-free gearing minimizes losses due to friction and optimizes the mechanical efficiency. Thanks to the gearing, maximum performance is easily achieved. In addition, the low initial and life cycle costs make these drives ideal for simple positioning and conveyor applications.1
