STOBER develops new generation of planetary gear units

No Other Product is as Compact and Versatile. STOBER develops new generation of planetary gear units.

The new generation of servo planetary gear units from STÖBER Antriebstechnik offers drives that are the most compact on the market in their power range and with their diversity of combinations and options. What’s more, any motor series can be directly attached in any available size. This variability allows STOBER to create the right drive solution for any application. In contrast to the prior generation, STOBER also equips the new planetary geared motors with an electronic nameplate, which makes commissioning controllers and drive controllers much faster.

Pforzheim, 2019-10-01 – STOBER has developed the third generation of servo geared motors, which are the most compact drive solutions on the market with their level of versatility. To achieve this, the lengths of the new gear units were significantly reduced. All STOBER motors, such as the EZ series or sensorless Lean motors, can be directly attached without an adapter, in any desired size.

Thanks to this compactness, the user benefits from a smaller installation space, lower weight, greater torque and a resulting power density that is increased by up to 65%. The mass moment of inertia is lower because the motor adapter is no longer needed, which allows the full dynamics of the drive to be used. This is a real advantage for the customer, particularly noticeable with small and medium sizes in shorter cycle times.

The new generation also features the highest backlash stability and ruggedness. The excellent housing and gearing quality ensure high acceleration torques as well as the highest running accuracy and precision at the same time. Users benefit from acceleration torques increased by 60%, a speed increase of 45% and an increase of the torsional stiffness by up to 50%.

Flexibility from the Motor Attachment to the Bearing System

The most impressive feature of the new generation of planetary gear units is its enormous variability. This means that not only are the gear units able to be combined with different STOBER motors via direct attachment, they can also be attached to all third-party motors in any size using variable adapters. The drive specialist offers a one-of-a-kind interface technology for this purpose. STOBER motor adapters are available with different couplings as well as in the ServoStop variant with an integrated brake.

The adapters can also be combined with standard or reduced-play gear units. In particular, the large design of the STOBER adapter with an extra-large motor plate makes it possible to connect the most compact STOBER gear units with motors of very large sizes—a truly unique selling point.

Depending on the application, another advantage compared to the competition is that the right bearing can be selected, whether deep-groove ball, cylindrical roller or angular contact bearing. These low-friction bearings enable generally higher speeds.

Thanks to this enormous variety, engineers have all the options in the design phase to put together exactly the right drive solution for any application. A smaller motor to optimize efficiency? A smaller drive controller might go well with that—which also lowers costs.

Easier Commissioning Thanks to Added Electronic Nameplate

Another special feature of the new generation is the electronic nameplate. In combination with the STOBER electronics, every geared motor automatically sends its electronic, mechanically relevant data by plug and play to the corresponding drive controller upon commissioning. As a result, the geared motors are uniquely identified. This eliminates high-effort, error-prone parameterization, which shortens the total system configuration significantly.

Meet us at the SPS

STOBER will present the new generation of servo planetary gear units for the first time at the SPS IPC Drives in Nuremberg, hall 3A booth 451 at the end of November. Sizes 2, 3 and 4 will be available from 1st October 2019, sizes 5 and 7 from 1st March 2020 and sizes 8 and 9 from 1st May 2020. Since the 1980s, STOBER has specialized in the development of planetary gear units, the premier class of drive technology! At the end of 2019, we presented the 3rd generation of planetary servo gear units, bringing drive solutions that are the most compact on the market for their performance range and enormous variety of combinations and options!
