1.  State the characteristic features of synchronous motor. Ans:   a.  the motor is not inherently self starting b.   The speed of operation…

Case i) Under excitation, Ebph < Vph . Zs = Ra + j Xs = | Zs |  ?? ? ? = tan-1(Xs/Ra) ERph  ^ Iaph = ?, Ia lags always by angle…

The Blondel diagram of a synchronous motor is an extension of a simple phasor diagram of a synchronous motor. For a synchronous…

Due to the losses in a transformer, its output power is less than the input power. ∴ Power output = Power input…

When synchronous motor is over excited it takes leading p.f. current. If synchronous motor is on no load, where load angle ? is very…
