Synchronous Machines Revised: October 4, 2021 1 of 23 EXPERIMENT Synchronous machine with DACI Synchronous Machines OBJECTIVE Three-phase Synchronous Machines account for a high percentage of this country s power generation. Understanding the machine s behavior and determining its equivalent network and performance characteristics are of prime importance to a power engineer. This experiment studies the characteristics of doubly-excited Synchronous motors and generators. Specific tests are run to determine equivalent circuit parameters, torque, and power factor control.

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.

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.

Small synchronous machines – use slip rings and brushes. Larger machines – brushless exciters are used to supply the dc field current. A brushless exciter is a small ac generator with its field circuit mounted on the stator and its armature circuit mounted on the rotor shaft. The 3-phase output of the exciter generator is rectified to direct

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.
