12V NEMA 17 stepper motor planetary gearbox high efficiency 1:54 reduction ratio
42BYGH603motor with Powder metallurgy 42mm planetary gearbox, the holding torque is 3.8 Kg.cm at 12V. The current is 0.4A. If the customer needs a higher torque, they can choose a higher reduction ratio, from 3 levels of reduction ratio, which we also call the number of gear trains. The first stage ratio is consists of 1/4 and 1/6. The second stage has ratios of 1/15, 1/18, 1/25 and 1/36. While the third stage has 1/54, 1/65, 1/90, 1/112, 1/155 and 1/216. A higher reduction ratio will result in lower speed and higher torque.

Mechanical Dimension
Unique Design for High Power Density
High power density is one of the many planetary gearbox advantages.
This is mainly due to the many planets in the gear system, which allow for efficient power distribution.
