Armature slot radial clearance-gauging device

Abstract

A radial clearance measurement device includes a pair of opposed drive heads, connected by an adjustable strut. Each drive head is fitted with a radial distance measurement device including a plate adapted to slide within a dovetail groove in a radial stator core slot, a spring-loaded plunger adapted to engage a surface of an armature bar located in the radial stator slot, and a linear voltage displacement transducer for measuring distance between the dovetail groove and the armature bar. The device is adapted to move through the bore of the stator, with the plungers engaged with armature bars in diametrically opposed radial stator core slots.
