BLDC Motor

It is an electric motor containing permanent magnets, also known as a permanent magnet synchronous motor (PMSM motor). The stator winding generates alternating current through electronic control, thereby generating a stator transformation magnetic field, which interacts with the magnetic field generated by the permanent magnets on the rotor, thereby generating rotor rotation.
