Nema11 28HSP 1200g.Cm Holding Torque Miniature Stepper Motor With Gearbox

Nema11 mini geared 28HSP 1200g.cm holding torque with planetary gearbox stepper 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.
