Effect, design accuracy requirement should be met by laminating back core internal diameter and grooved size.
Common motor stator core is formed using silicon steel plate stacking, to reduce eddy-current loss, the induction generated in iron core
Electric current, the circulation in the plane perpendicular to flow direction, makes iron core generate heat, in order to reduce eddy-current loss, the iron core of transformer
With silicon steel sheet stack insulated from each other at making to be vortexed in the circuit of thin-and-long, by lesser section, to increase on eddy current path
Resistance, the silicon in silicon steel increases the resistivity of material, also functions to the effect for reducing vortex.
According to the size of required stator core, silicon steel sheet is cut into elongated, then overlaps forming, it is thick to reduce vortex
Degree is thinner, and the slip of splicing is narrower, and effect is better, but greatly increases working hour, the effective cross-section of iron core is reduced, so using silicon
It is both advantageous and disadvantageous that steel disc makes stator core.
