Stober has developed the third generation of servo geared motors, which it claims are the most compact and versatile drive solutions on the market in their power range. To make this possible, Stober has significantly reduced the length of the new gear units. What’s more, all Stober motors can be directly attached without an adapter, in any desired size.
As a consequence of the compact unit size, users benefit from lower weight, higher torque, and an increase in power density of up to 65%. There is also a space-saving benefit to installation. Another real advantage of the integrated motor gearbox for the customer is that as a motor adapter is no longer required the mass moment of inertia is reduced, which allows the full dynamics of the drive to come into play.
Additionally, the highly robust new generation range also features high backlash stability. And with excellent gearing quality, high torque acceleration, operational accuracy and precision are also achieved. In fact, users benefit from an increase of acceleration torques of 60%, an increase in speed of 45% and an increase of the torsional stiffness by up to 50%.
Stober’s UK director, Martin Preece says: “The most impressive feature of this new generation of planetary gear units is its enormous versatility. Not only can these gear units be combined with different Stober motors via direct attachment, they can also be attached to all third-party motors of any size with our modular adapter range.” Depending on the application, another big advantage is the option of selecting the output bearing configuration.
