2. An axial flux motor, comprising:
a rotating shaft, the rotating shaft configured to rotate around a first axis;
a rotor assembly mounted fixedly onto the rotating shaft, the rotor assembly configured to rotate around the first axis, the rotor assembly comprising:
a rotor disc; and
a plurality of rotor disc teeth provided on a first side of the rotor disc; and
a stator assembly mounted freely onto the rotating shaft, the stator assembly comprising:
a stator base comprising a yoke with a ring shape;
a plurality of electromagnet assemblies attached onto a first side of the yoke, the first side of the yoke facing toward the first side of the rotor disc, the plurality of electromagnet assemblies configured to urge the rotor assembly to rotate around the first axis due to a rotating magnetic field with the plurality of electromagnet assemblies and its interaction with the rotor, an electromagnet assembly from the plurality of electromagnet assemblies comprising:
a core comprising a plurality of core layers stacked onto each other;
a first fixture attached to a first end of the core, the first fixture comprising a first securing part at one end of the first fixture;
a second fixture attached to a second end of the core, the second fixture comprising a second securing part at one end of the second fixture; and
a coil winding wound around the plurality of core layers, the first fixture, and the second fixture, wherein the yoke is configured to be secured between the first fixture and the second fixture.
