Title: HIGH SPEED ELECTRIC MACHINE FOR DRIVING AN AERONAUTICAL PROPULSION DEVICE
Abstract:
An electric machine is provided which includes a rotor disk extending along a radial direction and having a rotor flange attached to or formed integrally with the rotor disk and extending substantially along the axial direction. A plurality of rotor magnets are mounted on the rotor disk and supported by the rotor flange such that the rotor flange absorbs centrifugal loads exerted on the magnets and enables high speeds of operation.
