First, the principle of brush motorTo clarify the problem, you should have a rough idea of how the brush motor works. Next, a three-electrode, two-pole internal rotor brush motor is used as a demonstration.
Two, brushless motor working principle
First, the brushless motor is not a DC motor, although the model is powered by a DC battery, but after a brushless ESC, the transition is transferred to the three-phase alternating current to three polarities. As can be seen from the following figure,

A stepping telephone switch is an automatic telephone switch composed of selector and relay. It uses mechanical actions to replace the wiring actions of the telephone switch operator. When a user calls a dial-up, the selector in the switch changes the connection position step by step as the pulse current is triggered during the dial-up, and the telephone line between the caller and the called user is automatically connected.
