Carbon Brushed DC Motors ensure that the commutation process remains free from sparks and helps conduct electric current between the moving parts of the motor. This prevents the motor, or commutator, from wearing out. These motors are commonly used in consumer goods, small appliances, and automotive applications. 38D x 57Lmm, 3.6~9.6V
