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,

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.
