or resin to secure coils and provide structural rigidity to the stator. Shaft/Bearings

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. DIY Air Core Axial Flux Motor/Generator

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.

Connect the phases in either a Star (Y) or Delta configuration. Star is common for DIY builds as it provides higher voltage at lower RPMs. (enameled copper) for hand-winding; square wire can improve

Unlike traditional radial motors where flux moves out from the center, axial flux moves through the face of the motor between parallel discs.

Secure the stator between the two rotors. The air gap —the distance between magnets and coils—is critical; smaller gaps significantly increase power but require higher precision to prevent contact. DIY Air Core Axial Flux Motor/Generator This means there is no magnetic attraction between

To maximize efficiency, a typical DIY build uses two rotor discs with magnets sandwiching a single stator disc. Essential Materials Recommendation Magnets
