Brushless DC motor consists of a motor body and driver, which is a typical mechatronic product. The stator winding of the motor is mostly made into a three-phase symmetrical star connection, which is very similar to that of a three-phase asynchronous motor. The rotor of the motor is glued with magnetized permanent magnets, and in order to detect the polarity of the motor rotor, a position sensor is installed in the motor. The driver is composed of power electronic devices and integrated circuits, whose functions are: to accept the motor start, stop and brake signals to control the motor start, stop and brake; to accept the position sensor signal and forward and reverse signals to control the inverter bridge power tube on and off to produce continuous torque; to accept the speed command and speed feedback signal to control and adjust the speed; to provide protection and display, etc.
