Abstract
An air cycle machine includes a turbine section, a compressor section, an axial flux magnetic gear system electromechanically coupling the turbine section to the compressor section, and a stabilization system for at least one shaft of the air cycle machine. The axial flux magnetic gear system includes a stator, two rotors, a winding system, and a control module. Each rotor interacts with the stator such that the rotor rotates when the axial flux magnetic gear system is exposed to an electrical current. The winding system stabilizes the position of the rotors along their rotational axes. The control module is configured to supply the electrical current to at least one of the winding system, the stator, and the rotors to drive rotation of the rotors. The stabilization system stabilizes the position of the at least one shaft of the air cycle machine along the shaft's rotational axis.
