Low-Noise Precision Gearheads for Sensitive Motion Control Applications
In many motion control applications, performance is not measured solely by torque and speed. Acoustic noise can be equally important, particularly in laboratory automation, medical devices, optical systems, testing equipment and other precision instruments where quiet operation improves both usability and system performance. FAULHABER has addressed this requirement with the introduction of the new 22GPT LN and 32GPT LN low-noise gearheads.
Why Low Noise Matters
Traditional gearheads can introduce audible noise that may be undesirable in:
-
Laboratory and analytical equipment
- Medical devices
- Optical and imaging systems
- Test and measurement equipment
- Precision automation systems
- Scientific instruments
The new GPT LN series has been specifically developed to reduce operational noise while maintaining the performance characteristics expected from the FAULHABER GPT platform
Key Features
-
Up To 10 dB Noise Reduction
-
The new low-noise variants feature an optimised design incorporating a plastic input stage, enabling noise reductions of up to 10 dB when compared with standard GPT gearheads. This improvement is achieved without sacrificing durability, reliability or torque performance.
-
-
High Torque In A Compact Package
-
The 22GPT LN delivers up to 2.2 Nm of torque in intermittent operation, while the larger 32GPT LN provides up to 8 Nm. Both models are designed to accommodate occasional peak torque demands for applications requiring high performance within limited installation space.
-
-
Built For Demanding Environments
-
The stainless-steel housing provides robust protection, making these gearheads suitable for industrial and demanding operating environments. The units support operation from -30°C to +110°C and maintain efficiency even when subjected to frequent load changes
-
Typical Applications
These applications often require a combination of low acoustic emissions, compact dimensions and reliable torque transmission
-
Laboratory automation systems
- Medical and diagnostic equipment
- Optical positioning systems
- Test and measurement equipment
- Precision robotics
- Semiconductor handling equipment
- Automated scientific instruments
The 22GPT LN and 32GPT LN gearheads can be combined with compatible FAULHABER motors, encoders and controllers to create complete motion-control solutions tailored to application requirements. Their compact size and efficiency make them a practical option where installation space is limited but performance cannot be compromised
