How much noise reduction do the low-noise GPT gearheads offer compared to standard models?

The 22 GPT LN and 32 GPT LN reduce noise by up to 10 dB compared with the standard version, while still transmitting occasional peak torques of up to 4 and 12 Nm, respectively.

What torque and speed range does the largest GPT gearhead deliver?

The 42 GPT series can achieve intermittent torque of up to 25 Nm, with continuous torques between 6 and 18 Nm and speeds up to 24,000 rpm.

What is the operating temperature range for the new GPT gearheads?

Standard and low-noise variants operate from −30° to +110°C, while the HT models operate between −30° and +120°C.

3 Key Points

What happened
FAULHABER launched its new GPT gearhead family, engineered for high torques and compact performance. The lineup includes standard versions with diameters from 14 to 42 mm, low-noise variants (22 GPT LN and 32 GPT LN) that reduce noise by up to 10 dB, and HT models for robust environmental conditions. The 42 GPT series can achieve intermittent torque of up to 25 Nm, with continuous torques between 6 and 18 Nm and speeds up to 24,000 rpm.
Why it matters
The new gears are designed to work with FAULHABER's existing DC drives and motors, allowing matched combinations without additional connecting elements—a practical advantage for system integrators building compact drive systems. Low-noise variants address applications used near people or where multiple motors operate together, expanding the addressable market for collaborative and sensitive applications.
What to watch
The product line offers reduction ratios ranging from 3:1 to 1437:1, operating temperature ranges from −30° to +120°C depending on variant, and gear backlash of 0.8° or 0.6° for precise positioning. The gearheads are available now with three or four gear stages in numerous configurations.
