A symmetric six-phase flat wire winding balances branch potentials to stop loop currents, raise slot fill factor, and cut insulation cost.

Independent main and auxiliary windings let an ironless disc generator deliver multiple voltage outputs without sacrificing power density or space use.

An outer-circumference aerostatic bearing stabilizes large rotor discs, preventing axial flutter while enabling precise concentricity and higher torque.

Segmented magnet regions and dual excitation coils strengthen X- and Z-direction vibration while avoiding the large current of conventional layouts.

Flexible interfaces let stacked linear motor units hold small air gaps, raising force density and positioning accuracy in lithography.

Fluid pressure creates a gap between the axial flux rotor and stator, preventing tilt, friction, and wear in a compact pump.
