Brushless motor is a reliable and durable type of motor widely used in fields such as drones and electric vehicles. Unlike traditional brushed motors, motors do not require brushes to achieve current steering, thus having better performance and lifespan.
Returning to the issue of wiring, brushless motors typically have three wires: red, black, and white. The white line is used to transmit control signals for the motor. The method of wiring depends on the type of controller you are using.
If you are using a speed regulating motor controller, you need to connect the red wire to the square of the power supply, the black wire to the power supply, and the white wire to the signal input port of the controller. The controller will adjust the motor speed based on the signal on the white line.

Another common type of brushless motor controller is brushless ESC, which can control the motor speed through PWM signals. In this case, the red wire needs to be connected to the power supply, while the white wire is connected to the signal input port of the ESC.
No matter which type of controller you use, ensure that all wiring is secure and reliable, and pay attention to proper installation. In addition, you can also refer to the relevant manuals for brushless motors and controllers to ensure correct wiring and configuration.
In summary, the connection of the three wires of a brushless motor depends on the type of controller you are using. By correctly connecting the red, black, and white wires based on the signal input method of the controller and the motor, the motor can be successfully driven.
