<P>PROBLEM TO BE SOLVED: To provide a spinning machine, a winding device and a textile machine, capable of detecting periodic abnormality of a rotating body to improve detection accuracy. <P>SOLUTION: A spinning machine monitors at least one of torque and a rotation speed of a motor for driving a rotating body for drafting or winding up to determine the presence or absence of periodic abnormality of the rotating body on the basis of the monitoring result. For example, when a fiber bundle that moves with the rotation of the rotating body has such an abnormality that its thickness periodically varies, the load torque acting on the motor varies or the rotation speed of the motor varies. Therefore, the machine can monitor at least one of the torque and the rotation speed of the motor to determine the presence or absence of the periodic abnormality of the rotating body, thereby detecting periodic abnormality of the fiber bundle to be drafted or wound up by the rotating body. <P>COPYRIGHT: (C)2013,JPO&INPIT |
