Dear Mr.SH,

Thanks for brushing up my Electrical theory which is about 30 years old.

Reasons:-For laminated cores:- to reduce core(Iron) loss,Better insulation to ground

Easy handling and stacking, even distribution of magnetising current etc.

For design please refer to M.G.Say-AC machines design.

Single core:- Bulky to handle. The magnetism( distribution) will be only

pheriperal .

Please remember this forum is to discuss some valuable doubts

and is not a teaching / coaching college !
