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...
