Video-How to Use Planetary Gear Systems for Increased Torque in Drills

Planetary gear systems are primarily used for one or more of the following reasons:

  1. Reverse Motion
  2. Transmit more torque than one gear set will allow
  3. High reduction rates
  4. Use with other sets for multiple speeds
  5. Input and output need to be coaxial

Using a planetary gear system in a cordless helps to decrease speed / increase torque all while keeping the shafts coaxial. It also has a function that allows the ring gear to slip when the torque exceeds the desired limit.
