Redundant electrical machine for driving a means of propulsion

A redundant electrical machine for driving a propulsion means, having a drive system, wherein the drive system has

• a stator arrangement having at least two stator winding systems,
• rotor arrangement having at least one rotor, wherein each rotor has at least one permanent magnet, and
• wherein
• each stator winding system is assigned one of the rotors, wherein a respective stator winding system and the rotor assigned thereto are arranged with respect to one another so as to form a respective air gap between one another, such that the respective stator winding system and the permanent magnet of the rotor assigned to the respective stator winding system are able to interact electromagnetically with one another across the respective air gap during normal operation of the electrical machine,
• and wherein
• the electrical machine has a movement device for mutually moving the faulty stator winding system and the rotor assigned thereto out of a normal position for a case of a fault that occurs in a faulty one of the two stator winding systems, wherein the movement device is designed such that, by virtue of the movement out of the normal position, the air gap between the faulty stator winding system and the rotor assigned thereto is increased.
