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.
Claims13
A method for checking the alignment of a stator core comprising:
- placing a laser source and a target a given distance apart on a stator core;
- activating said laser such that said laser strikes said target;
- measuring on said target where said laser strikes;
- and
- interpreting the measurement to determine any misalignment of said stator core in said given distance.

A method for checking the alignment of laminations being assembled into a stator core, comprising:
- placing a laser in a slot in a first series of laminations;
- placing a target in a matching slot in a second series of laminations;
- projecting said laser to said target;
- measuring where on said target said laser projection strikes;
- interpreting said measurement for misalignment of said second series of laminations;
- and
- correcting any misalignment by at least one of, re-aligning the second series of laminations and adjusting the next series of laminations to compensate for any misalignment.
