ABSTRACT:
The rotor spinning machine includes a plurality of asynchronous motors for driving the operating elements of the machine. The motors run up from a standstill condition to an operating speed under the initial mass load of the operating elements. The machine includes a single soft-start control apparatus control circuit configured with the motors and the soft-start control apparatus for individually and successively connecting the motors to the soft-start control apparatus in a predetermined hierarchy.
