um of the instantaneous values ofthe resultant currents (shown in drawn line) must be zero at anymoment, not only during the permanent condition, but also dur-ing the transition period existing before the permanent condi-tion is reached. It is interesting to apply this to the resultant magnetic… … Fig. 18. — Construction of Starting Transient of Rotating Field. As is well known, three equal magnetizing coils, placed underequal angles and excited by three-phase currents, produce a result-ant magnetic field which is constant in intensity, but revolvessynchronously in space, and thus can be…
