The electric adjustment is the electronic governor. The function is to convert the voltage input from the battery into 5V output to the servo, flight control, receiver, etc., and the other function is to obtain the throttle signal from the receiver to control the speed of the motor.
The ESC is divided into brushed ESC and brushless ESC. Brushed ESC is the device that controls the brush motor. Brushless ESC is the device that controls the brushless motor. Brushed ESC generally has four lines and two. The strip is connected to the positive and negative poles of the power supply, and the other two are connected to the two electrodes of the motor. It is necessary to insert another signal line to connect with the receiver;
The brushless ESC is generally two power lines, one signal line and three lines connected to the motor. The power line is connected to the positive and negative poles of the power supply, and the signal line is connected to the receiver.
Parameters on the ESC:
30A indicates that the maximum current is 30A, 2-4s refers to the battery that supports 2 to 4s, BEC output 3A 5V, where BEC represents a circuit module that converts the voltage input from the battery into a voltage of 5V for flight control. , receiver, steering gear, etc., if the ESC does not have BEC output, it must provide 5V voltage for flight control, etc.
The ESC with the logo OPTO indicates that the ESC without power supply is the ESC without BEC.
