4mm Micro Coreless DC Motor – 8mm Model NFP-D0408

4mm Coreless Motor, Coreless DC Motor


3.7V DV Brushed Motor Model NFP-D0408 Data Sheet

DC Coreless motors, as the name suggests, have no iron core in the rotor. Its three characteristics are as follows:

  • Not having an iron core in the rotor prevents cogging caused by magnetic induction; hence the rotation is smooth, with minimum noise and vibration.
  • Longer service life due to less galvanic corrosion.
  • Linear speed/torque characteristics allow easier control.
