How Does A BLDC Motor Works?

A brushless DC (BLDC) motor, also known as an electronically commutated motor (ECM) or synchronous DC motor, is a motor that operates using electronic commutation rather than the brushes and commutator found in a brushed DC motor.
Brushless DC motors consist of a permanent magnet rotor and a fixed stator with coils wound around the stator. The stator coils are energized by an electronic controller in a specific sequence to produce a rotating magnetic field that interacts with the rotor's magnetic field. The interaction between the stator and rotor magnetic fields results in the rotation of the rotor.

The electronic controller determines the timing and sequence of current entry into the stator coil, which is critical to the efficient operation of the motor. The controller uses information from sensors, such as Hall effect sensors or encoders, to determine the position of the rotor and adjusts the current to the stator coil accordingly.
