Brushless motors typically consist of multiple coils, each of which needs to be switched on and off in a specific chronological order to generate a magnetic field. In the brushless motor drive circuit, a transistor or switch is used to control the on-off of the coil, and the on-off state of the transistor can be adjusted by PWM signal.
