Brushless DC motor, or BLDC motor, consists of two types: internal rotor and external rotor. It is an electric motor without brushes and commutators. The stator current is adjusted according to the position of the permanent magnet in the rotor to generate torque. Although it is called a "DC" motor, it is actually a permanent magnet synchronous motor (PMSM) that uses three-phase electricity. It is called a "brushless DC motor" because it can replace brushed DC motors in many applications; Therefore, BLDC motors are also called EC (Electronic Commutator) motors to distinguish them from mechanical commutator motors that contain brushes.
