Abstract
A motor controlling system is disclosed. The motor controlling system is integrated in an apparatus having roll-to-roll mechanism, and comprises a linear light source, at least one camera and a modular electronic device. When a continuous web material is discharged by an unwinding unit of the roll-to-roll mechanism so as to be further transferred to an inspection unit, the at least one camera is controlled by the modular electronic device to capture at least one material image. Subsequently, the modular electronic device conducts a defection inspection for a segment of the continuous web material by applying an image process to the at least one material image. As a result, in case of there being at least one defect found, the modular electronic device stops a plurality of motors of the apparatus from running, thereby making the segment of the continuous web material be positioned on an inspection platform.
