Drives for rehabilitation and prosthetics
Mastering movement.
Climbing stairs, tying shoelaces, grabbing a fork – the emulation of human movements with mechatronic systems is one of the greatest challenges for engineers. Highly innovative companies rely on drive systems from maxon for precise movements.
Our product recommendations.
Motors
Many movements involve large forces, but at the same time a high level of dynamics is required, since the motors must constantly change the direction of rotation due to the movement. In addition, a compact design that takes up as little space as possible must be considered.
Gearheads
Our gearheads combine maximum power with low weight and low noise levels. This does not affect the performance of the prosthesis and increases user comfort.
Encoders
Encoders are essential for the dynamic control of prostheses. During normal, conscious movement, reflex loops between muscles, nerves, and the brain interact about 20 times per second. For a prosthesis or an exoskeleton, high-performance sensors are required to reproduce the necessary motor skills as closely as possible.

Frequently asked questions
How big is the gearhead backlash?
maxon gearheads differ in their gearhead backlash. For the standard gearheads, this value is indicated in our catalog on the respective product page under Average Backlash.
Are there zero-backlash gearheads?
Zero-backlash gearheads have very little free play. A maxon gearhead with very low backlash is currently in development (Cycloflex). Zero-backlash gearheads can also be integrated by Harmonic Drive.
Gearhead direction of rotation?
The gearhead direction of rotation is irrelevant in the application (CW and CCW)
Are the gearheads backdrivable?
Planetary gearheads are designed for efficiency and therefore not intended to be backdrivable. Single-stage or two-stage gearheads may be backdrivable in some cases. With a three-stage gearhead, however, backdrivability is not possible. Even “zero-backlash” gearheads are not backdrivable.
What range of encoder resolutions can be offered?
Encoder resolutions start at 1 cpt to 65536 cpt (RIO encoder). Different absolute encoders (single-turn, multi-turn) are also available up to a 19-bit resolution.
Are dual-loop solutions/two encoders possible on one motor controller?
Yes. The EPOS 4 supports dual-loop mode (two encoders).
