Knowledge — ESC

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.

An electronic governor is an electronic device used to control the speed and torque of a brushless motor. The main principle is based on PWM (Pulse Width Modulation) technology and closed-loop control algorithms. In an electronic governor, PWM technology is used to control the current and speed of the motor. It controls a constant-value DC power supply through a switching tube (usually a MOSFET) to produce a square wave of a certain frequency, and controls the motor current and speed by adjusting the duty cycle of the square wave. A three-phase full-bridge circuit is usually used in electronic speed controllers...

A brushless motor governor, also known as a brushless ESC, is an electronic device used to control the speed of a brushless motor. The main function of a brushless motor governor is to control the speed and steering of the motor, allowing the motor to adapt to different work loads and operating environments. The working principle of a brushless motor governor is based on the induction potential of the motor and the operating characteristics of the electronics. The main components of a brushless motor governor include the power tube, the control circuit and the sensor.The power tube is the core...
