Consider the following statements regarding salient pole rotor type synchronous machines:
1. Salient pole synchronous machines have a large diameter and short axial length.
2. Air gap between the stator and rotor is uniform.
3. Salient poles are laminated to reduce eddy currents.
4. Salient pole synchronous generators are employed in hydro-power plants.
5. They have robust construction and noiseless operation.
The correct order of the statements is
1
Only 1, 2 and 4
