Abstract
A device and method are disclosed for inspecting core laminations of an electrical machine, such as an AC induction motor. The core laminations define inner diameter and outer diameter slots preferably in a predetermined orientation with respect to one another. The inspection device of the invention includes a bed plate defining at least one key channel to align with the inner and outer diameter slots in the predetermined orientation. A first key is slidable in the key channel to engage an inner diameter slot. An outer diameter slot is engaged by a second key if the predetermined orientation has been achieved. If the predetermined orientation has not been achieved, the second key will not engage the outer diameter slot. A plurality of post members may be inserted into registered slots provided in a stack of core laminations to facilitate visual inspection of several attributes.
