Class B Insulation 2 Phase Nema 17 42mm Hollow Shaft Stepper Motor for Smooth Motion
High Torque Hybrid Stepper Motor.
High Torque Hybrid Stepper Motors are motion systems allowing to have a high positioning precision.
With their high power already at low speed, their stall torque and the possibility to divide the steps in micro steps, stepper motors can provide direct and precise motions in a small volume.
Hybrid technologies
Permanent magnet
Step angle 1.8°
