What is BLDC Stator Core?
A BLDC Stator Core (Brushless DC Motor Stator Core) is the stationary magnetic core inside a brushless DC motor. It is typically manufactured by stacking precision-punched electrical steel laminations to form the stator body and its winding slots.The stator core provides the magnetic path for the motor and supports the copper windings. When current flows through the windings, the resulting magnetic field interacts with the rotor magnets to generate torque and rotation.
