    • PROBLEM TO BE SOLVED: To supply energy at an ideal voltage ratio in response to the type of a motor in a spinning machine or a spinning machine system. SOLUTION: At least three direct current voltage cables are connected to electric sources. Herein, at least one direct current voltage cable is commonly connected to at least two direct current voltage sources, and electric current loads are selectively connected to two of three direct current voltage cables. Thereby, (a) an electric voltage U1 and U2 between a first direct current voltage cable and a second direct current voltage cable, (b) an electric voltage U1 between the first direct current voltage cable and a third direct current voltage cable, and (c) an electric voltage U2 between the second direct current voltage cable and the third direct current voltage cable are at least selectively supplied.

    • PURPOSE:To prevent the yarn breakage in restarting a spinning machine, by suddenly rotating spindles in restarting a motor in the spinning machine, tightly stretching relaxed yarns, operating the motor in the inertial rotation, starting the main motor, and accelerating the rotation of the spindles to the normal motion. CONSTITUTION:In stopping a spinning machine, yarns passing through front rolls to spindles are relaxed to cause snarls by all means. In restarting a motor (M) of the spinning machine, mans for directly starting the motor (M) driving and rotating the spindles, e.g. a pushbutton switch (PB1) for start-up, an auxiliary relay (CR1) and a solenoid contactor (MS1) for driving the motor (M), are operated to rotate suddenly the motor (M) and spindles, and yarns in the relaxed condition are tightly stretched. The motor (M) is directly subjected to the inertial rotation with a power source cutoff means (TR1), and then driven with a power source connecting means (TR2) before the rotation of the motor (M) is stopped. Thus, the motor (M) is transferred to the normal motion.
    • 目的:为了防止重新启动纺纱机时的纱线断裂,通过在纺纱机中重新启动电机时突然旋转主轴,紧紧拉伸松弛的纱线,在惯性旋转中操作电机,启动主电机,并加速旋转 心轴正常运动。 规定:在停止纺纱机器时,通过前辊到纺纱的纱线放松,一定会引起咆哮。 在重新启动纺纱机的马达(M)时,直接启动马达(M),驱动和旋转主轴,例如, 用于启动的按钮开关(PB1),用于驱动电动机(M)的辅助继电器(CR1)和电磁接触器(MS1))被操作以使马达(M)和心轴突然旋转,纱线处于放松状态 条件紧张。 马达(M)用电源切断装置(TR1)直接进行惯性旋转,然后在电动机(M)的旋转停止之前用电源连接装置(TR2)驱动。 因此,马达(M)被转移到正常运动。
