The carbon brush is a part of the brushed motor that tops the surface of the inverter. When the motor rotates, the electric energy is transmitted to the coil through the inverter. The following micro-motor manufacturer will specifically introduce the application of carbon brushes in micro-motors. A brush is a sliding contact that conducts an electric current. The function of the carbon brush introduced by the micro-motor manufacturer is to introduce the rotor current required by the micro-motor manufacturer's motor operation into the rotor coil through the connecting piece on the slip ring. The coincidence degree and smoothness of the carbon brush and the connecting piece, The size of the contact surface affects its life and reliability. In the DC motor of the micro-motor manufacturer, it is also responsible for the task of commutation of the alternating electromotive force induced in the armature winding of the micro-motor manufacturer.

The efficiency of a micro-motor refers to the ratio of its mechanical power to its input power, and the design of the micro-motor is to improve efficiency with a lower loss to the maximum extent. The following is a specific introduction to how to improve the efficiency of micro-motors. In general, we divide the loss of micro-motors into two types, one is mechanical loss and the other is electromagnetic loss, such as copper loss, iron loss, hysteresis loss and so on. To reduce the loss of the rotor of the micro-motor, it is usually to reduce the resistance of the rotor winding, such as using relatively thick and low resistance wires, or increasing the cross-sectional area of the rotor slot. The material of the rotor of the micro-motor is also very critical, such as using a copper rotor. The loss can be reduced to about 15%.
