Abstract
Abstract The rotor of an electromotor which directly drives a spinning element is arranged in the extension of the shaft of the rotating spinning element. The shaft on which the motor rotor is mounted is supported by means of supporting discs. At each supporting location at least two supporting discs are provided on which the shaft unrolls. The diameter of the supporting discs is several times the diameter of the shaft.
