Synchronous Machines Revised: Octo 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 Size: KB. Synchronous Machines 2 In this chapter, we concentrate on conventional synchronous machines whereas the brushless dc motors will be discussed later in a separate chapter. Synchronous Machine Structures Stator and Rotor The armature winding of a conventional synchronous machine is almost invariably on the stator and is usually a three phase Size: KB. Synchronous Machines Introduction One might easily argue that the synchronous generator is the most important component in the power system, since synchronous generators • Are the source of 99% of the MW in most power systems; • Provide frequency regulation and load following; • Are the main source of voltage control;. As synchronous machines operate at effectively constant speed, the open circuit voltage test provides the relationship between field current and induced voltage for all load conditions. The induced open circuit voltage is sometimes known as the "excitation voltage", or even simply as the "excitation".

The no-load or open-circuit voltage is generated in the armature windings of a synchronous machine when the armature terminals are open-circuited and the rotor is rotating at synchronous speed while the field winding is induced open-circuit voltages in the three phases are given by. Figure illustrates a typical open-circuit .

is a platform for academics to share research papers. motors (synchronous machines), it is important to have a brief overview of the operation of a synchronous motor, most common faults, common test methods, how Motor Circuit Analysis (MCA) works with large synchronous motors, basic steps for analysis of synchronous stators and rotors, and, expected test results. A synchronous motor (Fig. ) is electrically identical with an alternator or a.c. generator. In fact, a given synchronous machine may be used, at least theoretically, as an alternator, when driven mechanically or as a motor, when driven electrically, just as in the case of d.c. machines. Most synchronous motors are rated between.
