Planetary gear motors, usually cylindrical in form, are made of steel, brass, and plastics. It's easy to get very low gearings in a small space using planetary gearings. They have a large amount of meshing tooth surface area. So, you can get large amounts of power transfer without worrying about stripping gears.

A planetary gear train consists of several planet gears, a sun gear and an outer gear or annulus. It also consists of a movable arm or a carrier that holds the planet gears. The carrier, along with the planet gears, rotates around the sun gear. In the gearing configuration, the outer gear or annulus rotates with the planet gears. In the planetary gear system, the axes of the gears are usually parallel to each other and are concentric. Disadvantages include high bearing load, inaccessibility, and design complexity. However the advantages of planetary gears over parallel axis gears are compact size, higher efficiency, and low noise level. The gear train itself has a higher level of stiffness, along with its uniform mass distribution, making it highly stable. In planetary gear systems, the load is shared by two or more teeth.

ZHAOWEI is committed to providing high quality planetary geared motors offering low noise, strong torque, long lifespan, and high efficiency.
