Method and apparatus for checking stator core alignment
View Patent ↗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.
1. An apparatus for checking the alignment of a stator core comprising:
a stator core;
a laser source; and
a target;
wherein said laser source and said target are aligned a distance apart along an axis of said stator core within an inner diameter of said stator core;
wherein the point at which said laser source strikes said target indicates a measurement of misalignment of said stator core.
2. The apparatus of claim 1 , wherein a plurality of said laser sources and said targets are used.
3. The apparatus of claim 1 , wherein said stator core is a partially assembled stator core.
4. The apparatus of claim 1 , wherein said target contains gradients.
