    Abstract: A system for inspecting a stator stack includes a rotary table, an imaging device configured to take a plurality of images of a portion of the stator stack including a stator slot, an illuminator configured to apply illumination through the stator slot, and an alignment and monitoring system configured to monitor and orient the stator slot relative to the imaging axis. The alignment and monitoring system includes a tilting system configured to move the stator slot between a plurality of orientations relative to an imaging axis, the imaging device configured to take a respective image at each of the plurality of orientations, a controller configured to control the tilting system based on one or more measurements of each image, and a processor configured to analyze each image and select an orientation of the stator slot as an optimal orientation for inspection of the stator slot.

    Abstract: A calibration system for multiple image sensors includes a manufacturing apparatus, a first imaging sensor, a second imaging sensor positioned at a different location than the first imaging sensor and configured to capture at least one different wavelength than the first imaging sensor, a calibration artifact, and an imaging calibration module. The imaging calibration module is configured to obtain first and second images of the calibration artifact via the first and second imaging sensors, determine first and second pixel mappings between the first and second images and a common coordinate system, according to a location of the calibration artifact in the first and second images, convert an image of a manufacturing object captured by the first imaging sensor to the common coordinate system, and convert an image of the manufacturing object captured by the second imaging sensor to the common coordinate system.

    Abstract: A method of inspecting a stator stack includes disposing the stator stack on a support surface of an inspection system, and performing a depth measurement of a stator slot. The depth measurement includes rotating the stator slot along a first direction to a plurality of first orientations, taking a first image at each of the first orientations, and measuring a depth based on at least one of the first images. The method includes performing a width measurement of the stator slot, which includes rotating the stator slot along a second direction to a plurality of second orientations, taking a second image at each of the second orientations, and measuring a width based on at least one of the second images. The method further includes inspecting edges of the stator slot in the at least one of the first images to detect a potential deviation.
