  • Method and apparatus for measuring compression in a stator core
    Patent number: 7946023
    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.

  • METHOD AND APPARATUS FOR CHECKING STATOR CORE ALIGNMENT
    Publication number: 20080231844
    Abstract: In one embodiment the present invention provides for a method for checking the alignment of a stator core that comprises placing a laser source 14 and a target 18 a given distance apart on a stator core 10 and activating the laser such that the laser strikes the target. Then measuring on the target where the laser strikes, and interpreting the measurement to determine any misalignment of the stator core in the given distance.
