Abstract
An open-end spinning machine has spinning stations and a magnetic and gas bearing with a stator at each of the spinning stations. A shaftless spinning rotor being electrically drivable with a single motor includes a series of spinning cups with different properties at each of the spinning stations for receiving fibers to be spun, and an electric rotor at each of the spinning stations forming an axial field motor with the magnetic and gas bearing and the stator. The spinning cups and the electric rotor have axially opposing end surfaces, and the end surfaces of the electric rotor and of one of the spinning cups at a time are coupled together to form a functionally appropriately releasable connection as a structural unit at each of the spinning stations.
