In a case scenario where the stator core is made from solely one solid piece of material-the associated heatproduced and currents will amount to a large sum-resulting in a melted stator core.
A stator core is built up as laminations are placed side-by-side in order to make a complete circular or ringed layer. The next layer is laid, offsetting each layer like a brick or cinder block wall.
As such, there is a need to laminate the stator core and insulate each layer. Eason being that the circulatingcurrents will be brought down to a size that is much more smaller and controllable. Hence. Allowing the heatgenerated by the currents to be managed by pumping cooling gases(hydrogen or air)through and/or acrossthe stator core structure.
Above all this makes sure that the stator core`s performance is not compromised or even driven to the nointof terminal malfunction.
