Short questions and answers EE1251 Electrical Machines II 1. Why almost all large size Synchronous machines are constructed with rotating field system type? The following are the principal advantages of the rotating field system type construction of Synchronous machines: • The relatively small amount of power, about 2%, required for field system via slip-rings and brushes. • For the same air gap dimensions, which is normally decided by the kVA rating, more space is availabl...
