Example 17: In a hydroelectric power plant, 100 m3/s of water flows from an elevation of 120 m to a turbine, where electric power is generated. The total irreversible head loss in the piping system from point 1 to point 2 (excluding the turbine unit) is determined to be 35 m. If the overall efficiency of the turbine–generator is 80

Smaller synchronous machines are sometimes used for private generation and as standby units, with diese l engines or gas turbines as prime movers. According to the . arrangement of the field and armature windings, synchronous machines may be classified as . rotating-armature type. or . rotating-field type. Types of Synchronous Machine

Construction of synchronous machines The rotor of a synchronous machine is a large electromagnet. The magnetic poles can be either salient (sticking out of rotor surface) or non-salient construction. Non-salient-pole rotor: usually two- and four-pole rotors. Salient-pole rotor: four and more poles.

Synchronous Machines Revised: October 4, 2021 2 of 23 Figure 1: Cross-sections of synchronous machines. As shown in Figure 1, the rotor can be of either the salient-pole type or the cylindrical (non-salient-pole) type. The machine used for this experiment is somewhat salient, but the impact of the salient is negligible.

synchronous motor has a synchronous reactance of 1.95 ohm/phase. Compute the max. torque in N-m which this motor can deliver if it is supplied from a constant frequency source and if the field excitation is constant at the value which would result in unity power factor at rated load. Assume that the motor is of cylindrical rotor type.
