The DC geared motor is made on the basis of ordinary DC motor, plus the matching gear reducer. Let's take a look at the reasons why the brush of the DC gear motor is too large:
1. Cause of failure: The brush of the wound-type motor is not smooth due to wear during the long-term operation, the brush pressure is not enough, the slip ring is not round, or the oil droplets or other debris on the bearing falls to the slip ring. Between the carbon brushes and other reasons, the brush will spark.
2, the treatment method: eliminate the brush sparks: the fine sandpaper can be used to polish the contact surface, adjust the pressure of the brush, and check whether the slip ring is round, also apply clean cotton yarn, slightly rub the gasoline, wipe the slip ring and carbon Brush, eliminate oil on the bearing and carbon brush, and protect the slip ring and carbon brush.
