For an air spinning frame, reluctance motors are provided for each spinning place
to drive the pairs of rollers of the drafting unit, the drawing-off means, and
the friction roller. Thereby, for the run-up of a spinning place, e.g., after a
thread break, a specific frequency converter is provided. After reaching the stationary
operating speed, a switch over onto a further frequency converter takes place,
at which time, the corresponding reluctance motors of the other spinning places
are driven in parallel. By the use of reluctance motors it can be done without
a complex speed regulation means. A specific dimensioning of the reluctance motors
permits a very fast run-up and a particularly good efficiency during the stationary operation.
