Abstract
The invention relates to a rotating electrical flux-switching machine, comprising a rotatable tubular rotor (2), an inner first stator (3), and an outer second stator (4) that is concentric and spaced apart relative to the first stator (3), wherein the rotor (2) is arranged concentrically relative to the first and second stator (3, 4) and is arranged between the first and the second stator (3, 4) in such a way that a first air gap (10) is formed between the first stator (3) and the rotor (2), and a second air gap (11) is formed between the second stator (4) and the rotor (2). The invention also relates to an aircraft comprising a rotating electrical machine of this type.
