Helical bevel geared Lean motors

Efficient without any compromises: Helical bevel geared Lean motors.

Save on everything without reducing performance and energy efficiency!

When you use the encoderless Lean motor coupled with a first-class STOBER helical bevel gear unit, you can reduce the size of your drives while achieving a motor efficiency of up to 96%.

BENEFITS

This compact and very stable drive unit offers the best conditions for energy-efficient tasks in areas such as packaging and machine tools, automation or robotics.

And it also enables extremely space-saving machine and assembly concepts.

The very rigid gear units in this series feature high-quality helical gears that guarantee unsurpassed smooth operation and backlash stability.

K gear units paired with Lean motors are a winning combination, especially due to the extremely compact, rugged geometry of the housing at an exceptionally low weight. And its efficiency is excellent thanks to the motor’s IE5 classification rating.

The jointless, torsion-resistant block design and directly attached Lean motor form an extremely stable drive unit.

The motor shaft and gear unit output are on the same level, which makes the design of your machine or system so much simpler.

The geared motors of this series are mainly used when applications call for low weight, a small installation space and, above all, high energy efficiency. For more productivity and profitability.
