Helical bevel servo geared motors

Designed to be absolutely practical: Helical bevel servo geared motors.

In this series, helical bevel gear units and synchronous servo motors form a compact unit featuring very convenient installation dimensions and a high power density.

The result is an extremely wide range of efficient design options for the packaging and machine tool industries as well as for automation and robotics. STOBER is an experienced manufacturer for helical bevel servo geared motors and supplies a large number of customers from different industries.

BENEFITS

This coupling-free combination of a K series gear unit and EZ series synchronous servo motor reduces the space requirements and rotating masses, thereby lowering the total weight.

This increases the dynamics and saves costs.

All geared motors in this series of helical bevel servo geared motors feature high-quality helical gearing that guarantees unsurpassed smooth operation and backlash stability.

K gear units paired with EZ motors are a winning combination, especially due to the extremely low weight, a high volume performance and high torque.

The jointless, torsion-resistant block design and the directly attached EZ motor combine to form a highly rigid 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.

Helical bevel servo geared motors: The geared motors of this series of helical bevel servo geared motors are used primarily when applications call for high dynamics, low weight and, above all, a small installation space.

Thanks to the technology that provides robust bearings and high-quality gearing, the gear units of the KS series are extremely durable and tip-resistant.

They can be used in continuous operation without any problems – even at high speed levels.

The advantage of direct attachment: the bevel gear stage, planetary gear unit and EZ motor form a compact unit featuring extremely convenient installation dimensions. Complemented by the square mounting flange, the geared motors can be mounted close together.
