Abstract
Drive arrangement for spinning stations of an OE spinning machine. The feed rollers of the spinning stations can be driven by an electric motor and the draw-off rollers by another electric motor. At least one of these two motors is a synchronous motor. Each of the two motors can be fed supply currents of adjustable frequency by a reverse rectifier, with the rotational speed of one of these two motors being adjusted as a function of the rotational speed of the other motor which is sensed by a pulse generator in such manner that the set rotational speed ratio of these two motors remains constant at operating speeds and in that the operating speeds are ensured even in case of brief network outage.
