3. Axial-field machines
3.1 Architecture
The machine consists of a disk-shaped rotor rotating opposite a disk-shaped stator. The magnetic field generated by the permanent magnets exists as soon as the distance between rotor and stator is sufficiently small. It creates a strong attractive force between the rotor and stator, the value of which per unit area is approximately :
