摘要：
The invention provides for the spinning units of a multi-position open-end spinning machine to be driven by a common AC drive motor powered by a static inverter enabling the power supply frequency to the AC motor to be controlled for controlling the rate of acceleration and the operating speed and the rate of deceleration of the AC drive motor. This facilitates a method of mass start-up and mass stopping of a friction spinning machine are disclosed.
