'''Gearbox''' is a mechanical device utilized to increase the output torque or change the speed of a motor. The motor's shaft is attached to one end of the gearbox and through the internal configuration of gears of a gearbox, provides a given output torque and speed determined by the gear ratio. | '''Gearbox''' is a mechanical device utilized to increase the output torque or change the speed of a motor.

Planetary gearboxes are named so due to their resemblance to the solar system. The components of a planetary gearbox include a sun gear, ring gear and planetary gears. The sun gear is the central gear which is fixed in the center, ring gear (annulus ring) which is the outer ring with inward-facing teeth, and the planetary gears which rotate around the sun gears and mesh with both the sun and ring gear. | Planetary gearboxes are named so due to their resemblance to the solar system.
