An electric motor comprises a rotor and a stator. The rotor includes a housing having an inner surface and an outer surface, a first end, and a second end. Permanent magnets are located along the inner surface of the rotor housing. At least one groove is defined in the first end of the rotor housing. A sealing member includes at least one protrusion located in the at least one groove. A honeycomb panel may be located in a recess defined in the outer surface of the rotor housing. The electric motor may form part of a propulsions system for an aircraft, used to drive a rotor assembly including rotor blades.
