Designed to be absolutely practical:
Helical bevel servo geared motors.
In this series, helical bevel gearboxes 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.
- Helical bevel gearbox with EZ motor
- KEZ: Versatile and compact, for exceptional backlash stability
- KLEZ: Elegant, dynamic and completely without offset
- KSEZ: Strong, stable and with the highest possible power density
This coupling-free combination of a K series gearbox 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 feature high-quality helical gearing that guarantees unsurpassed smooth operation and backlash stability.
K gearboxes paired with EZ motors are a winning combination, especially due to the extremely compact geometry of the housing featuring an 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 gearbox 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 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 gearboxes 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 gearbox 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.
