PRODUCT DESCRIPTION
NEMA17 0.9° 42mm hybrid stepper motor 2 phase motor for 3d printer
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.
Permanent magnet and hybrid technologies are used to provide a full range of solutions.
The absence of mechanical commutation gives to these motors a long life time which is usually given by the sleeves
according to the load applied on the shaft.
