Abstract

A rotor for a motor of an electric aircraft is provided. The rotor includes a retention band surrounding a plurality of magnets. The retention band is designed to retain the magnets in their positions and provide a way for heat to dissipate from the magnets. The retention band may also reduce eddy currents found within the rotor. A method of manufacturing a rotor with a retention band is also provided.
