Axial flux stator and rotor core


Axial flux stator and rotor cores are the core magnetic components of axial flux motors, distinguishing themselves fundamentally from traditional radial flux motor cores in structure and working principle. Unlike cylindrical radial flux cores, they adopt a unique disc-shaped, flat layout, with magnetic flux traveling parallel to the motor’s rotation axis rather than radially. This special structural design defines their compact and high-performance characteristics.
Fabricated from high-precision laminated silicon steel sheets or advanced soft magnetic composites, the stator and rotor cores form the key magnetic circuit of the motor. The stator core carries winding coils to generate alternating electromagnetic fields when electrified, while the rotor core, usually fitted with permanent magnets, interacts with the stator magnetic field to produce driving torque. Some coreless stator designs further eliminate iron loss and cogging torque, delivering smoother operation and higher efficiency.
