1. The electronic speed controller for drones, also known as the Electronic Speed Controller, abbreviated as ESC, is divided into brushed and brushless electric controllers. The yellow color in Figure 1 represents the most common brushless electric regulator. Electric control receives start, stop, and brake signals to control the start, stop, and brake of the motor; Receive forward and reverse signals to control the on/off of each power transistor in the inverter bridge, causing the motor to generate continuous torque. Receive speed commands and speed feedback signals to control and adjust motor speed. Simply put, electric tuning is used to drive motors.

2. This corresponds to the brushless motor used in conjunction with the brushless electric motor, and the ABC of the electric motor corresponds to the three wires of the motor.

3. Flight Control, also known as Flight Controller, has two common types of flight controls: one is a commercial flight control from DJI, and the other is a very common F3 open-source flight control. From the appearance alone, flight control has much richer interfaces than electronic control. It is the "brain" of the flight controller, collecting information from sensors, receiving remote control commands, processing them, and then transmitting control signals to electronic control, driving motors to respond to control and achieve the goal of controlling the aircraft's attitude.

In summary, electronic control cannot replace flight control.
