4mm Tiny Coreless DC Motor – 12mm Model NFP-D0412

Moving Coil Motor Model NFP-D0412-3978 Data Sheet

---

Coreless DC motors are different in construction than the usual can motor. Moving Coil or Coreless Motors, instead of rotating iron armature, is made from lightweight material with the magnet wire wound around it. Usually have a less current loss. It doesn’t draw as much current as some other motors, so when powered by a battery the battery will last longer. They are designed for rapid acceleration.
