    Tips: Nema 4 micro stepper structure.

    Nema 4 micro stepper is mainly composed of base body, rotor, gear and linear guide.

    1. The base body also acts as a stator, with magnetic poles, stator teeth, coils and control circuits on its surface.
    2. The rotor is located above the stator, with mover teeth on the lower surface. The function of guide rail is equivalent to a linear bearing, keeping the rotor in place.
    3. There is a shell above the guide rail and rotor for sealing. The rotor is separated from the surrounding elements by an air gap.
