Axial flux stator and rotor core


Axial flux stator and rotor cores are the core magnetic components of axial flux motors, distinguishing them radically from traditional radial flux motor structures. Unlike conventional motors where magnetic flux travels radially, axial flux motors guide magnetic flux parallel to the rotating shaft, relying on paired disc-shaped stator and rotor cores to form efficient magnetic circuits.
Fabricated from laminated high-grade silicon steel sheets, both cores effectively suppress eddy current loss and reduce iron loss during operation, greatly improving motor energy efficiency. The stator core features a flat, segmented disc structure with wound copper coils. When energized, it generates a stable alternating magnetic field. The rotor core, usually embedded with high-performance permanent magnets, rotates driven by the stator’s magnetic torque.
This unique structural design brings prominent advantages. The flat and compact layout shortens the axial size of the motor, achieving higher power and torque density than radial flux motors. Additionally, the optimized magnetic flux path minimizes magnetic leakage and operational heat loss. Thanks to these strengths, axial flux stator and rotor cores are widely applied in new energy vehicles, industrial precision equipment and aerospace devices, becoming key components for high-efficiency, lightweight motor upgrades in modern power systems.
