Description

Technical Field

[0001] The utility model relates to the technical field of carbon brush structures, in particular to a carbon brush structure of a six-phase micro brushed motor with limiting function. Background Art

[0002] The six-phase micro brush motor is a type of brush motor. The six-phase micro brush motor is a rotating motor that contains a brush device and converts electrical energy into mechanical energy (motor) or mechanical energy into electrical energy (generator). The working principle of the carbon brush is realized through friction and conductive properties. The carbon brush is usually composed of magnetic powder and conductive material. They are fixed on a mechanical part that can rotate or slide. When the mechanical part starts to move, the carbon brush contacts the rotating or sliding surface and generates friction. At this time, the carbon powder will be rubbed onto the surface, and the conductive material plays a conductive role. Because carbon has good conductivity, the contact between carbon powder and conductive material can form a conductive path. When the current flows through the carbon brush, it can be transferred to the rotating or sliding parts, thereby acting on them. The conductivity and friction of the carbon brush are key factors to ensure its normal operation. If the conductivity of the carbon powder is not good or the friction is insufficient, the conductive path may be interrupted, affecting the working effect of the mechanical parts. In addition, the carbon brush also has the characteristics of self-lubrication. The carbon brush can replenish the worn parts by releasing carbon powder and maintain a good friction effect;

[0003] However, existing carbon brushes usually use a single spring to push the carbon brush head tightly against the rotating shaft. The stability of the single spring is poor. When in use, the carbon brush head is easy to contact the rotating shaft at a certain angle, resulting in a small contact area between the carbon brush head and the rotating shaft, affecting the conductive performance of the carbon brush. Therefore, it does not meet the existing needs. In this regard, we propose a six-phase micro brush motor carbon brush structure with a limit. Utility Model Content
