Abstract
The present invention a method and apparatus for measuring the compression of a stator core 10 that comprises attaching a measuring device 22 to a tensioner 20, placing the tensioner on an end of a through-bolt 12 of the stator core, and performing at least one act of tensioning the stator core 10 with the tensioner. Then measuring a compression state of the stator core by the measuring device registers determining the amount of relative compression achieved by the act of tensioning, the relative compression is the amount of actual compression of the core and the amount of stretch of the through-bolt. Finally determining an actual compression state of the stator core based on the measuring.
