Electronic Speed Control is abbreviated as ESC, which is mainly divided into brush ESC and brushless ESC.
About the connection of brush ESC and brushless ESC, generally it is like this:
|Connect the input wire of the ESC to the battery|
|The output wires of the ESC (two with brushes and three without brushes) are connected to the motor|
|Connect the signal line of the ESC to the receiver|
In addition, the ESC generally has a power output function, that is, between the positive and negative poles of the signal line, there is a voltage output of about 5V. The signal line supplies power to the receiver, and the receiver supplies power to control equipment such as steering gear.
With the vigorous development of brushless motors, brushless ESCs occupy the mainstream of the market. Many brands of brushless electronic governor have also appeared on the market. Not every brushless ESC can be matched with the motor, mainly related to the power of the ESC. If an ESC with insufficient power is used, it will cause the power tube on the ESC to burn out, and the ESC will not work. Therefore, the choice of ESC must be based on the power of the ESC, and the compatibility between the ESC and the motor. The ESC is not compatible with all motors. It must be selected according to parameters such as the power of the motor.
The input of the ESC is DC, and it can be connected to a regulated power supply or a lithium battery. The general power supply is around 2-6 lithium batteries. The output is a three-phase pulsating DC, which is directly connected to the three-phase input of the motor. If your motor reverses after power-on, you only need to swap any two of the three wires. There is also a signal wire connected to the ESC, which is used to connect with the receiver to control the operation of the motor. The signal wire must be connected to a common ground.
About the application
The main application of ESC is in toy models such as airplane model, car model, ship model, flying saucer, flying disc and so on. These models use ESCs to drive the motors to complete various instructions, imitating their real work functions, in order to achieve an effect similar to the real situation. So there are ESCs specially designed for model airplanes, ESCs designed for car models, and so on. The function of the ESC is to control the motor to complete the specified speed and action.
