1. A motor controlling system, being integrated in apparatus comprising an inspection unit and a roll-to-roll mechanism consisting of an unwinding unit and a winding unit, and comprising:
a linear light source, being disposed at a first position for facing a first photographing region between the unwinding unit and the inspection unit;
at least one first camera, being disposed at a second position for facing the first photographing region; and
a modular electronic device, being coupled to the linear light source and the at least one first camera, and comprising a processor, a memory and a human machine interface (HMI), wherein the memory stores an application program, and the processor being coupled to the memory and the human machine interface;
wherein the application program includes instructions, such that in case the application program is executed, the processor being configured for:
controlling the linear light source to emit a first detection light for irradiating the first photographing region in case of a roll of a continuous web material being discharged by the unwinding unit by a feeding speed;
controlling the at least one first camera to acquire at one material image frames from a first segment of the continuous web material that is in the first photographing region;
applying at least one image process to the at least one material image, so as to generate a first material feature image;
extracting a plurality of defect features from the first material feature image, and then determining whether there are existing any defects in the first segment of the continuous web material by matching the plurality of defect features with a plurality of reference defect features;
stopping a first motor of the unwinding unit, at least one second motor of the inspection unit, and a third motor of the winding unit from running in case of there being at least one defect detected from the first segment of the continuous web material, so as to make the first segment of the continuous web material be positioned on an inspection platform of the inspection unit;
restarting the first motor, the at least one second motor and the third motor to run after receiving a transmission restarting command transmitted by the human machine interface.
