Triple the power

FAULHABER in introducing the most powerful power transmission technology in its size class to the market with the new 20/1R planetary gearhead: A diameter of 20 mm allows the stainless steel gearhead to achieve continuous torque of 800 mNm, and up to 1100 mNm for short periods during interval operation. Following intensive development with a comprehensive series of tests, the power output was able to be more than tripled in comparison to previous models. The input speed reaches 12,000 rpm. The 20/1R can be combined with DC, brushless motors and stepper motors with a diameter of 17 to 22 mm.

The output shaft of the 20/1R has no axial play thanks to the pretensioned ball bearing. The gearhead is available with one to five stages, and the span of the 16 possible reduction gear ratios ranges from 3.71:1 to 1526:1. There is also a choice between the normal temperature range of -10 to +125°C and a low temperature variant with -45 to +100°C. The typical temperature range for planetary gearheads made from metal is therefore extended considerably. Numerous product variants, including an autoclavable version, makes it easy to adapt to completely different applications. The connection of the new 20/1R planetary gearhead is compatible with its predecessor, the 20/1. When upgrading, the previous gearhead can be replaced with the new model without further changes.

FAULHABER specializes in the development, production and deployment of high-precision small and miniaturized drive systems, servo components and drive electronics with output power of up to 200 watts. The product range includes brushless motors, DC-micromotors, encoders and motion controllers. In addition, FAULHABER also offers customer-specific complete solutions for, among others, medical technology, automatic placement machine, precision optics, telecommunication, aerospace and robotics. FAULHABER has more than 1,600 employees worldwide.
