What is the difference between BLDC brushless motor and ordinary motor
BLDC means brushless DC. BLDC brushless motor is a form of motor, although called BLDC brushless motor, BLDC brushless motor is actually an AC motor. The stator winding of BLDC brushless motor is mostly made into a three-phase symmetrical star connection method, and BLDC brushless motor is very similar to three-phase asynchronous motor. The rotor of a BLDC brushless motor is coated with magnetized permanent magnets. In order to detect the polarity of the motor rotor, a position sensor is installed inside the motor. The BLDC brushless motor driver is composed of power electronic devices and integrated circuits. The function of the BLDC brushless motor is: the BLDC brushless motor receives the start, stop, and brake signals of the motor, and the BLDC brushless motor controls the start, stop, and brake of the motor; The BLDC brushless motor receives position sensor signals and forward and reverse signals. The BLDC brushless motor is used to control the on/off of each power transistor of the inverter bridge, and the BLDC brushless motor generates continuous torque; BLDC brushless motor receives speed commands and speed feedback signals, and BLDC brushless motor is used to control and adjust the speed; Provide protection and display, etc.
