Grundkurs Theoretische Physik 1nnected to . systems, and accordingly, their analysis was based on the rotating magnetic field produced by balanced polyphase currents. But the two-phase servomotor to be studied in Chapter 16 operates with unbalanced supply voltages, and as far as the single-phase motor of Chapter 17 is concerned,

https://doi.org/10.1007/978-3-662-61914-8The 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.
