Our Planetary Gear Motors offer high efficiency and provide excellent torque output when compared to other types of gear motors. They can handle a varying load with minimal backlash and are best for intermittent duty operation. With endless reduction ratio options, voltages, and sizes A planetary gear motor mimics a planetary rotation system, the input shaft drives the central gear, also known as the sun gear, which then turns the surrounding gears, also known as planet gears When you couple a dc motor with a planetary gearbox a speed reduction occurs resulting in increased rotational torque at the gearbox output shaft. Planetary gearboxes consist of an internal sun gear that drives multiple outer ring gears known as planet gears, hence its name. The efficiency loss in a planetary gear is typically about 3% per stage. This type of efficiency ensures that a high proportion (about 97%) of the energy being input is transmitted through the gearbox, rather than being wasted on mechanical losses inside the gearbox. Planetary gear motors come with some advantageous characteristics: High Torque Capabilities Sleek Inline Design High Efficiency Ability to Handle Large Reduction Ratios High Power Density
