Geared 1.8deg 0.4a 3.1kg.Cm 12v 42mm Diameter Nema 17 Hybrid Stepper Motor
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.
