Christian Posthoff,Konrad SchultzIn the discussion of transformers and also of salient-pole stators or rotors, reference was made frequently to . formed from individual . wound around cores by having them connected in series. Indeed, without this possibility of using coils of many turns, no practical electromagnetic devices for power conversion could be built at all.

Klassische Statistische Physik,The machines discussed up to this point, whether they are single-phase or polyphase, synchronous or asynchronous, generators or motors, are all operating with alternating currents and voltages. Their most important mode of operation is the sinusoidal steady state.

Transformers,The purpose of a power transformer, as explained in Section 1–3, is to enable different parts of a power system to operate at different voltages. Such a transformer may be interposed between a generator and a transmission line, between a distribution network and a load, etc. It should neither consume nor store any energy.

Electromechanical Energy Conversion,The great leap from the study of the static transformer to that of rotating generators and motors must be undertaken by the reader in several slow steps.
