1.33A 2.6kg.cm 2.8V 1.8 Degree Nema 17 Stepper Motor with planetary gearbox
The Nema 17 Stepper Motor Bipolar with 13.7:1 Planetary Gearbox is a stepper motor with 34mm body and 1.33A rated current, integrated a planetary gearbox of 13.7:1 gear ratio. Adding a gearbox to a stepper motor system can improve the motor’s performance by decreasing the load-to-motor inertia ratio, increasing torque to the load, and reducing motor oscillations.
Compared to the other two types of stepper motors, hybrid stepper motors provide higher torque with smaller step angle and have a better dynamic property. With the development of science and technology, especially the development of permanent magnet materials, semiconductor technology and computer technology, these stepper motors have been widely used in industrial automation, robotics, textile and medical industries.

Stepper Motors, Stepper Motor Drivers and Controllers
Stepper motors enable accurate positioning with ease. They are used in various types of equipment for accurate rotation angle and speed control using pulse signals. Stepper motors generate high torque with a compact body, and are ideal for quick acceleration and response. Stepper motors also hold their position at stop, due to their mechanical design. Stepper motor solutions consist of a driver (takes pulse signals in and converts them to motor motion) and a stepper motor.
