The invention discloses a motor stator inner contour surface defect rapid online detection method, and belongs to the technical field of defect detection, and the method comprises the following steps: employing a YOLO v6 algorithm to construct a defect prediction model; a calibration mold with a standard checkerboard arranged on the inner contour is adopted to calibrate the detection mechanism; the motor stator is placed on the placing platform; adjusting the position of the detection mechanism in the horizontal plane; collecting image parameters of the inner contour of the motor stator; and inputting the image parameters into the defect prediction model to judge the defect. The invention also discloses a detection device corresponding to the method. The invention provides a motor stator inner contour surface defect rapid on-line detection method and device, which can follow the production rhythm of a motor production line, rapidly realize rapid on-line detection of motor stator inner contour surface defects,
