Stacking Factor versus compression force
Stacking Factor versus compression force
(OP)
It is my understanding that the resultant stacking factor for an induction motor core is due to the lamination insulation layer but also the amount of compression on the core prior to welding/fastening. What is the best way to determine the compression force needed to obtain the maximum SF with a given lam thickness (.020" in this case)?





RE: Stacking Factor versus compression force
Some possible takeaways:
1 – you can measure stacking factor based on change in dimensions when compressed.
2 – High 90's is mentioned as typical
3 – 1 N / mm^2 has sounds like it might be some standard ... but whether for testing or typical of machines I'm not sure.

Clyde38....I didn't even think about the stress levels affecting the actual magnetic properties, rather only thought about removing air pockets/voids between the lams. Great info though for review!
