Knowledge — ESC

      （Piawn ESC parameters） Before making ESC parameter adjustments, we need to understand some basic concepts and considerations. ESC, full name electronic speed controller, is a device used to control the speed of the motor. It achieves precise control of motor speed by adjusting the input voltage and current of the motor. The adjustment of ESC parameters can affect the performance of the motor, including speed, torque, efficiency and other aspects. Correct parameter settings can make the motor reach the best state under different working conditions and improve the overall performance and efficiency of the equipment.    ...

Controlling a bidirectional Electronic Speed Controller (ESC) using PWM signals typically involves sending specific PWM values to control the motor's speed and direction. Below is a simple example control code using an Arduino to generate PWM signals and control a bidirectional ESC. Please make sure your bidirectional ESC is connected to the Arduino's PWM pins and powered correctly. #include <Servo.h>Servo esc; // Create a Servo objectvoid setup() { esc.attach(9); // Attach the ESC to pin 9 on the Arduino esc.writeMicroseconds(1500); // Initialize the motor to a neutral position delay(2000); // Wait for 2 seconds}void loop() { int throttle = 1500;...

The neutral stop signal is its unlocking signal
Using a 50Hz signal, the signal period is 20ms.
The percentage in the instructions refers to the percentage of the PWM control pulse width, not the actual duty cycle of the PWM signal (it is easy to misunderstand here).

A lot of researchers who want to control the operation of the thruster with a microcontroller to find a lot of information on the Internet, but found that a lot of them are not written very clearly, APISQUEEN roughly record how to solve.I hope you can exchange experience in the comments section, can help more people.We buy the ESC may be different, but the overall control idea is the same, so I believe you can certainly achieve your goal after reading this article. PWM signal:(1) PWM wave control (generally speaking ESCs are controlled by PWM wave at 50Hz, that is...

The brushless motor/thruster cannot be connected directly to the power supply. The phase sequence is controlled by the controller (ESC) in order to ensure the motor/propeller operates properly and can make the motor/propeller work more efficiently. If you need to use a brushless motor, please make sure to pay attention to the correct operation method to ensure the normal use and long life of the motor.
