12mm Coreless Motor DC Motor Model NFP-D1220

3V-9V DC Brushed Motor Model NFP-D1220 Data Sheet

The primary factors affecting the lifespan of brushed motors are abrasion due to rotational contact of the brush and commutator, and electric corrosion during polarity switching. While precious metal contact material minimizes electric corrosion.
