Can the generator be made without silicon steel? Can I make it hollow?
Silicon steel is used to magnetic, not the electromagnetic efficiency will be reduced, the ideal state is 100% of the electrical energy into magnetic energy, with more than 90% silicon steel may not be 50%, silicon steel that is not ah, how power can be, ah, what is this design, who died!
Creative, encouraging, encouraging, yes, at present, the hollow generator, motor have, but the efficiency is very low, can only be used for the production, there is no practical significance.
The hollow is not the generator. It is an air core reactor, not a silicon steel sheet.
