The difference between a brushed motor and a brushless motor is whether or not a commonly used brush is provided. A brushless motor has a coil wound on a rotor and a current is applied to the ring-shaped electrode mounted on the rotor by a graphite brush or a copper brush Electromagnetic conversion, to achieve the purpose of the electrode rotation.
Brushless motor rotor no coil, no need to spread to the current brush, the motor's electromagnetic coil in the stator, the power can be generated directly after the drive rotor rotation. No brush friction noise and resistance, the whole Less noise, higher power conversion efficiency, no maintenance, longer life expectancy.
What is the difference between brush motor and brushless motor?
Brush motor advantages and disadvantages
Advantages: cheap, simple technology
Disadvantages: low conversion efficiency; noise is relatively large; speed is not high; short life;
Brushless motor advantages and disadvantages
Advantages: high speed; large output torque; long life;
