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.
