Quick Takeaways
- FAULHABER has expanded its GXR and SXR DC motor families with 14 mm diameter models.
- The 1439 GXR is presented as a compact motor with high power density and up to 7 mNm of continuous torque.
- The 1439 SXR is described as a low-vibration and low-noise option with high torque for demanding small-drive uses.
- The update is relevant when buyers need to evaluate a motor, gearhead, and encoder as one compact motion package.
Industry Update
FAULHABER has introduced new 14 mm DC motors in its GXR and SXR families, adding smaller options for designers who need compact brushed DC drives. The company positions the additions as part of a wider portfolio that can be combined with matching gearheads and encoders.
According to FAULHABER, the 1439 GXR combines small size with high power density and delivers up to 7 mNm of continuous torque. The company also says its carbon brush design supports robust operation and a long service life.
The 1439 SXR is presented as a high-torque DC motor for demanding applications where low vibration and low noise matter. For equipment builders, the main change is not only a new motor diameter, but another packaged path for fitting a drive into limited installation space.
Buyer Considerations
Compact DC motor selection often depends on the full drive stack, not the motor alone. Buyers comparing these new 14 mm options should check the required torque-speed point, supply voltage, thermal conditions, expected duty cycle, and the available gearhead or encoder combinations before specifying a replacement or new design.
The update may be useful for medical devices, laboratory automation, compact actuators, precision instruments, and other equipment where diameter, acoustic behavior, service life, and feedback integration can limit supplier choice. It may also help sourcing teams compare whether a standard motor family can reduce custom engineering work.
Buyers should confirm mounting dimensions, shaft options, gearbox ratios, encoder resolution, electrical limits, and lifecycle availability directly with FAULHABER or an authorized channel before committing the motor to a production design.

Frequently Asked Questions
What changed in FAULHABER's DC motor range?
FAULHABER added 14 mm models to its GXR and SXR DC motor families, expanding the compact brushed DC motor choices available to equipment designers.
Why does a 14 mm motor option matter for buyers?
A smaller diameter can help when the motor, gearbox, encoder, wiring, and thermal clearance must fit inside a compact assembly without redesigning the whole mechanism.
What should engineers verify before selecting one of these motors?
Engineers should check torque and speed requirements, voltage, duty cycle, heat rise, gearbox fit, encoder needs, noise limits, and expected service life for the actual application.
