Product Details

Model: Jkongmotor 42mm JK42BL 12V 24V 36V Round Brushless Dc Motor with Planetary Gearbox 42x42mm

A planetary gearbox is a gearbox with the input shaft and the output shaft aligned. A planetary gearbox is used to transfer the largest torque in the most compact form (known as torque density).

A planetary gear is a type of gear system comprised of spur gears. In planetary gearing (also known as epicyclic gearing), a center gear, called a sun gear, serves as the input and driver of the set. Three or more “driven” gears (referred to as planets) rotate around the sun gear.
