When repairing electrical apparatus of any type, a common task is to ensure that machined fits are within acceptable limits of Geometric Dimensioning and Tolerancing (GD&T). This ranges from the simple, such as checking motor foot coplanarity, to the complex, including verifying the straightness of a stator bore as well as its concentricity with itself and with the bearings. The complexity of the task, of course, adds time, and time is never in surplus at a motor service center. Skipping these GD&T checks to save time can lead to mistakes and failures, with costs ranging from a few days of additional work to complete motor replacement and possibly lost production time for both the customer and the service center. In recent years, research has been conducted and tools have been developed that significantly reduce the time required to perform these tasks, enabling service centers to save time and ensure that all fits are within tolerance.
