Geared nema17 1.8deg 0.4A 3.1kg.cm 12v 42mm diameter Stepping Motor
Stepper motors are known for their accurate positioning
capabilities and high torque delivery at low speeds, but they
require careful sizing to ensure the motor matches the load and
application parameters, to minimize the possibility of lost steps
or motor stalling. 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.
