Stober Planetary Servo Geared Motors

Stober Planetary Servo Geared Motors

The most impressive feature of the new generation of planetary gear units is its enormous variability. All STOBER EZ series motors can be directly attached in any size you need – without adapters.

This compact drive gives you the benefit of up to 65% increased power density. And with the lower mass moment of inertia by leaving out a motor adapter, you can also utilize the full dynamics of the drive.

Planetary Servo Geared Motors from Stober are available in five series: PEZ: For high precision and smooth operation, PHEZ: For the highest precision and performance, PHQEZ: Quattro power for maximum power density, PHVEZ: For large gear ratios, and PEEZ: The attractive economy variant

PEZ Series

The decisive characteristic of the P series planetary gear unit is the high-quality helical gearing that gives you smooth operation that is second to none. When the P series is combined with our extremely compact, highly dynamic EZ motor, the result is a precise geared motor featuring high torsional stiffness and backlash stability.

Technical Data

  • Total ratio: 3 – 28

  • Allowed acceleration torque: 5.7 – 250 Nm

  • Backlash: 8 – 13 arcmin

  • Efficiency: 95 – 97%

PHEZ Series

The PH series planetary gear units are high-performance servo gear units with increased torsional and tilting stiffness. Here, their inner workings are also distinguished by our proven, high-quality helical gearing. The output shaft is designed as a flange. PH with EZ – the result is a high-performance geared motor, ideal for any kind of drive solution that has the highest requirements for rigidity, precision, and reliability.

Technical Data

  • Total ratio: 4 – 100

  • Allowed acceleration torque: 24 – 7500 Nm

  • Backlash: 1 – 4 arcmin

  • Efficiency: 93 – 96%

PHQEZ Series

PHQ is a precise servo gear unit with high-quality helical gearing as well as maximum torsional and tilting stiffness. For maximum torque. When it’s combined with an EZ motor, you get a geared motor that above all has an impressively innovative 4-planet system. Our Quattro power series is ideal for applications where space is precious – like for drives in pick-and-place applications.

Technical Data

  • Total ratio: 5.5 – 600

  • Allowed acceleration torque: 84 – 22000 Nm

  • Backlash: 1 – 3 arcmin

  • Efficiency: 90 – 96%

PHVEZ

PHV – a precise high-performance servo gear unit with proven high-quality helical gearing as well as very high torsional and tilting stiffness.

The gear units are especially ideal for large gear ratios.

PHV and EZ – as the two elements are very short, the combination gives you a geared motor that is extremely compact and highly dynamic.

Technical Data

  • Total ratio: 61 – 121

  • Allowed acceleration torque: 1638 – 7500 Nm

  • Backlash: 3 arcmin

  • Efficiency: 90%

PEEZ

The PE series are highly cost-effective planetary gear units for the economy range with high performance.
They also have the high-quality helical gearing typical of STOBER – for low noise development and the best smooth operation.
It’s a unique feature on the market in this price and product class!

When you combine this gear unit with one of our EZ motors you get the advantage of a very economical and also powerful geared motor. Especially in the automation and robotics industries.

Technical Data

  • Total ratio: 3 – 28

  • Allowed acceleration torque: 5.7 – 250 Nm

  • Backlash: 8 – 13 arcmin

  • Efficiency: 95 – 97%
