Product Description

Medical Detector 28mm Hybrid Stepper Motor 0.67A 1.2kg.Cm 4-Leads Mini Stepper Motor


      The motor is made of high-quality silicon steel material with high magnetic permeability and large resistance coefficient. The motor coil is made of pure copper enameled wire. The advanced winding process makes the copper wire evenly arranged, the motor temperature rise is lower, and the deformation problem will not occur for a long time.




Stepper motor are widely applied in 3D printer, mini cnc router, engraving machine, textile machine, medical equipment, stage light equipment, robotic, CNC router, music fountain, and other industrial automatic equipment.
