(PETG or Carbon Fiber Polycarbonate) or laser-cut wood/MDF for prototypes. Encapsulation

An air core (or ironless) axial flux motor/generator features a flat, disc-like architecture where the magnetic flux runs parallel to the axis of rotation, and the stator contains no ferromagnetic material. This design eliminates "cogging" torque, resulting in extremely smooth motion and high efficiency at high speeds due to the absence of iron-related energy losses like eddy currents.

or resin to secure coils and provide structural rigidity to the stator. Shaft/Bearings (PETG or Carbon Fiber Polycarbonate) or laser-cut wood/MDF

The coils are encased in a non-conductive medium (like epoxy or resin) rather than wrapped around iron teeth. This means there is no magnetic attraction between the stator and rotor when the motor is off, allowing for zero-drag rotation. or resin to secure coils and provide structural
