ST2818 - Miniature High Torque Stepper Motor - Nema 11
The smallest stepper motor construction size ST2818.. is suitable for applications which require high precision in small construction volumes (28 x 28 mm -Nema 11) with a long service life. At a resolution of 1.8°/step, existing controllers can also be used for this step motor.
The standardized shaft diameter of 5 mm makes it possible to install a cost-effective encoder in the double shaft version in order to monitor the rotation.
