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

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.
