<P>PROBLEM TO BE SOLVED: To provide a packaging apparatus and a motor controller by which the low-price, the miniaturization and the reliability improvement of the apparatus can be promoted, since the disturbance of a smaller amplitude than a regular disturbance or the disturbance accompanied by the change of which the oscillation period is late can be detected certainly due to the biting of a packaging film without arranging sensors of these kinds which come to be exclusive for the biting detection of the packaging film when the regular disturbance exists in an end sealer shaft in the packaging apparatus. <P>SOLUTION: The controller is equipped with a disturbance observer section 2 which can calculate a disturbance presumption value to a motor 1 from torque instructions and a motor speed and biting detecting sections 3 and 4 which can detect the biting integrity in the above end sealer shaft from the above disturbance presumption value. <P>COPYRIGHT: (C)2010,JPO&INPIT |
