Abstract:
A micromachine comprising:a rotor disk journalled for rotation in a stationary structure by a journal bearing; a plurality of radial flow rotor blades, substantially untapered in height, disposed on a first rotor disk face; an electrically conducting region disposed on a rotor disk face; a plurality of stator electrodes electrically interconnected to define multiple electrical stator phases and disposed on a wall of the stationary structure located opposite the electrically conducting region of the rotor disk; a first orifice in the stationary structure providing fluidic communication with the first rotor disk face at a location radially central of the rotor blades; a second orifice in the stationary structure providing fluidic communication with the first rotor disk face at a location radially peripheral of the rotor blades; and an electrical connection to the stator electrode configuration for stator electrode excitation and for power transfer with the stator electrode configuration as the rotor disk rotates.
