要約(英語): This paper demonstrates a control method that can reduce the start-up time of a weaving machine based on vector control. Traditionally, the induction motor used for a weaving machine was driven by a direct power grid connection, that can achieve a quick start-up time for the weaving machine. However, it is inefficient in steady-state operation. An inverter is utilized in the induction motor to obtain a higher efficiency than that of the induction motor directly connected to the power grid. However, the driving of the inverter slows down the start-up time of the weaving machine. This paper proposes a fast accelerating method for the weaving machine drive system, in which an open winding of an induction motor is connected in series to an inverter and delta-star switching unit. From the results, the start-up time of the proposed system is shown to be the same as that of the direct power grid connection. In addition, the inrush current of the proposed system is decreased by 37.7% compared to that of the direct power grid connection.
