摘要: A flyer frame has a first AC motor for obtaining a general rotational movement of various parts of the frame and a second AC motor for obtaining only a variable component of the rotational movement of the bobbin. An inverter is provided for operating the first and second AC motor. A controller is divided into a general section for operating the frame powered by AC power source, and a winding section for obtaining a winding control of the frame. The winding control section is operated by a DC current, which is usually supplied by an outside AC source. A DC output of the inverter is connected to the winding section via a diode or relay, which usually disconnects the DC line to the winding section and which is closed upon the occurrence of the power failure, for supplying a regenerating current from the inverter to the winding section. A desired winding control is thus maintained upon the occurrence of the power failure, until the stoppage of the frame, to prevent rovings at respective spinning positions from being broken.
