GATE ECE 1993 | Question-38

While starting a de shunt motor:

  1. reduced armature voltage $V_{n}$ and reduced field voltage $V_{\text {, }}$ should be applied and full regulator resistance $R$, should be included in the field circuit.
  2. reduced $V_{A}$ but full $V_{f}$ should be applied and $\mathrm{R}_{r}$ should be zero.
  3. rated $V_{n}$ and rated $V_{f}$ should be applied and $R_{r}$ should be zero.
  4. rated $\mathrm{V}_{a}$ and rated $\mathrm{V}_{f}$ should be applied and $\mathrm{R}_{r}$ should be maximum.
