LINEARSTEP [PFL20] Dispensing demo


This is a dispensing demonstration that uses a linear step (direct-drive type stepping motor) [PFL20]. Diameter of PFL20 is 20 mm, which is the smallest in LINEARSTEP series.

The direct-drive stepping motor uses a normal stepping motor as the base, and rotational motion is converted into linear motion using a rotor (female screw) and a shaft (male screw).


Motor outer diameter: 20 mm (2-phase PM type stepping motor)
Winding specification : Bipolar
Screw pitch : 1.2 mm
Resolution : 0.05 mm / step (1.2 mm / rev)
Stroke : 30 mm / 60 mm


  • Easy control
  • Simple structure
  • High efficiency
  • Long life
