브러시리스 모터와 브러시 모터의 차이점
The difference between brushless motor and brushed motor is whether there are brushes. Brushless motor has no brushes and realizes rotor commutation through electronic controller. It has the advantages of high efficiency, low noise and long life. Brushed motor realizes commutation through the contact between brush and rotor. It has the advantages of simplicity and low cost, but has disadvantages such as friction, wear and brush life.
