It is a ring-shaped structure composed of numerous silicon steel laminations (stator laminations), each of which has regular teeth. You can clearly see the layered texture of the laminations.
The teeth on the inner ring are used to accommodate the motor windings (coils), while the outer ring forms a complete magnetic circuit loop.
Applications
New energy vehicle drive motors (high-end electric vehicles and hybrid systems)
Industrial robot joints and precision servo motors
Unmanned aircraft and aerospace lightweight power systems
Key Advantages
As the "magnetic circuit framework" of the motor, when energized, the magnetic field generated by the coil will form a closed loop in the iron core, converting electrical energy into mechanical energy (in a motor) or vice versa (in a generator).
This segmented and stacked structure can significantly reduce energy loss caused by eddy currents compared to a single solid iron core, and is one of the key technologies in modern motor design.
