Replace the Carbon Brush to pay attention to the matter
Double servo motor rotor commutator car is specialized for some micro motor and motor vehicles, motorcycles starter motor produced by the high-end products, mainly for micro motor rotor commutator precision turning, motor commutator finish is relatively high , The spark between the brush can also be a lot of reduction, noise, so you can improve the performance of the motor. The Carbon Brush needs to be replaced after a certain degree of wear, but if it is ready to replace the new Carbon Brush, it is best to replace all the Carbon Brushes all at once, because if the new Carbon Brush and the old Carbon Brush are Mixed with the time, there may be uneven current distribution of the situation.
For a variety of models of large motor units, if the shutdown due to the replacement of Carbon Brushes affect the normal production, we under normal circumstances can be recommended to replace each 20% of the Carbon Brush, that is, each motor of each brush 20%, so the replacement, then about 1 to 2 weeks each time interval, and so on after the gradual run-in and then the remaining Carbon Brush replacement work, so you can ensure that the motor can be a normal continuous operation.
But we need to pay attention to our customers, in the same motor above, when the replacement of Carbon Brush, you should try to use the same type of Carbon Brush, but for the individual for special difficulties in large and medium-sized motor, you can also use Gemini , Because the twin-Carbon Brush sliding edge of the lubrication performance is still relatively good, so slide out once the use of can inhibit the spark of Carbon Brush, you can make the Carbon Brush to improve the operation.
In the motor Carbon Brush after a period of time will appear the phenomenon of wear and tear, or even just installed on the Carbon Brush will wear the situation, in the end what is the situation? How to solve it? Here are a few examples of the common motor Carbon Brush wear causes and solutions.
1, motor overload --- reduce and limit the motor load
2, commutator or collector ring on the oil --- cleaning commutator or collector ring
3, brush and brush the resistance between the uneven - cleaning and fastening joints
4, brush contact surface with abrasive particles --- re-run and clean the brush surface
5, the current distribution is not uniform --- adjust the brush pressure
6, brush models mixed --- can only install a type of brush
How to solve the motor Carbon Brush wear
Carbon Brush is a brush motor can not be missing a component, its main role is to external current (excitation current) through the Carbon Brush and added to the rotating rotor, that is, input current. As well as the static load on the large axis through the Carbon Brush into the earth (output current) and change the direction of current.

Motor Carbon Brush has four major roles:
1, the external current through the motor Carbon Brush and added to the rotating rotor;
2, the large axis of the electrostatic charge through the Carbon Brush into the earth;
3, change the direction of current;
4, the large shaft lead to the protection device to provide rotor ground protection, measuring the rotor positive and negative ground voltage.
In fact, the commutator is also composed of brush and commutation ring, Carbon Brush is a brush.
