The Difference Between Dc Brushless Motors And Brushed Motors In Micro-Pump Applications

In the DC motor, brush motor is the earliest contact with a class of motors, secondary school physics classroom to introduce the motor is also to show it as a model. The DC brushless motor is a new type of motor, which has been gradually applied to daily life in recent years. But in fact, as early as 1917, the basic idea of brushless DC motor has been born, because the brush motor brushes are easy to be worn out is a fatal shortcoming, which affects the brush motor in the field of the overall application, people need a can not need to be maintained on the long-term use of the motor to replace it. It wasn't until 1955, when D. Harrison and others in the United States first applied for a patent to replace the mechanical brushes of a brushed DC motor with transistorised commutation lines, that the birth of the modern brushless motor was officially marked. So what is the difference between them?
