8mm Micro Brushed DC Motor – 23mm Type Model NFP-D8523-3933

8mm Coreless Motor, Coreless DC Motor


Coreless Mini Motor Model NFP-D8523-3933 Data Sheet

Giving coreless designs significantly higher efficiencies (up to 90 percent) than traditional DC motors. The coreless design also reduces winding inductance, so sparking between the brushes and commutator is reduced, increasing motor life and reducing electromagnetic interference (EMI)
