FAULHABER is expanding its GPT family with two high-performance models that operate quietly—the 22GPT LN and 32GPT LN. These new gearheads have been specifically designed for applications where noise reduction is crucial, as in laboratories, optical devices, medical applications, or testing and measuring systems.

Like all models in the GPT series, the new low-noise variants combine high torques with a compact design and proven reliability, according to the company. They deliver up to 2.2 Nm and 8 Nm, respectively, for the 22GPT LN and 32GPT LN in intermittent operation and can manage occasional random peak torques of up to 4 Nm and 12 Nm. Thanks to their optimized design and an input stage with plastic gears, the 22GPT LN and 32GPT LN operate with extremely low noise without compromising performance, robustness, or durability. Compared to the standard version, the low-noise variants are able to reduce noise by up to 10 dB.

The stainless-steel housing provides reliable protection even in challenging environments. The gearheads are rated for a wide temperature range from –30 °C to +110 °C and maintain their high efficiency even during frequent or sudden load changes. This makes them ideal companions for high-torque motors.

Those using the new low-noise models will benefit from the proven GPT technology, which is now enhanced with a noise-optimized solution for sensitive environments.

FAULHABER develops, produces, and deploys high-precision miniaturized and miniature drive systems, servo components, and drive electronics with up to 200 watts of output power. This includes implementing customer-specific packaged solutions as well as numerous standard products such as brushless motors, DC-micromotors, encoders, and motion controllers. The FAULHABER trademark is recognized worldwide as a symbol of high quality and reliability in complex and demanding application areas, such as medical technology, factory automation, precision optics, telecommunications, aviation and aerospace, and robotics. From the DC-motor with a continuous torque of 200 mNm to the filigree micro drive with an outer diameter of 1.9 mm, the FAULHABER standard range can be combined in more than 25 million different ways to create an optimum drive system for a particular application. At the same time, this technological construction kit is the basis for modifications that allow it to configure special versions to meet specific customer needs.
