Planetary Gearhead

Maxon Precision Motor Planetary Gearhead

Planetary gears have simultaneous meshing between the sun gear and planet gears and between the planet gears and the internal gear. The sun gear is connected to the motor and a carrier, supporting the planet gears, is connected to the output. Single stage planetary gears can achieve reduction ratios up to 10:1. Ratios above 10:1 utilize a two stage design where the carrier of the first stage drives the sun gear of the second planetary stage.


Industry usage includes:

  • Robotics
  • Spaceflight applications
  • semiconductor manufacturing equipment
  • Factory automation equipment
  • Medical diagnostics
  • Surgical robotics
