The life of a micro brushed DC motor is proportional to the current

1. When the working current of the motor is small, the wear and heat generation of its internal electrical and mechanical components are small, and the life is relatively long.
2. However, when the working current of the motor is too large, it will cause greater wear and heat generation of the electrical and mechanical components inside the motor, thereby accelerating the decay of life.
3. Therefore, in order to extend the life of a micro brushed DC motor, the working current of the motor should be controlled as much as possible to avoid exceeding its rated current.
4. In addition, the wear resistance and heat dissipation performance of the motor can be improved by reasonable design and selection of high-quality materials, further extending its life. Therefore, the life of a micro brushed DC motor is proportional to the current. Micro brushed DC motors are small motors that are usually used in some small electronic devices. They are powered by a DC power supply and achieve current conversion through contact between brushes and brushes.
