28 BYGH Nema 11 Gearbox Stepper Motor 4.22 V 1.8 Degree Micro With ROHS

Gearbox Nema 11 28 BYGH Stepper Motor 4.22 V 1.8 Degree Micro High Quality With ROHS

The 28BYGH Stepper Motor is made of 32MM-51MM silicon steel sheet and rare earth magnetic steel. The air gap is small and the torque is large. It has the advantages of high anti-resonance characteristics and low heat generation.

Another reason to use a gearbox with a stepper motor is to increase the torque available to drive the load. When the load is driven by a motor-gearbox combination, the gearbox multiplies the torque from the motor by an amount proportional to the gear ratio and the efficiency of the gearbox.
