Synchronous machines

, 2023
This article describes the fundamentals of electrically-excited rotating synchronous machines, either used as motors and generators. Firstly, the main fields of use for these machines are reviewed and their peculiarities are highlighted for the different areas of application.

SYNCHRONOUS STARTING OF SYNCHRONOUS MACHINE

Electric Machines & Power Systems, 1993
ABSTRACT Synchronous starting is one of the methods for starting large synchronous motors by small synchronous generators. The equations for Concordia's interlocked generator-motor block logic for synchronous starting are derived in detail. The equations for software implementation including saturation and motor friction torque are presented ...

Synchronizing transients and synchronizers for large machines

Electrical Engineering, 1940
IT IS a curious fact that the phenomena encountered in synchronizing operations have received scant attention in the technical literature even though the phenomena have been encountered ever since two synchronous machines were first operated in parallel, and even though a large number of synchronizing operations are performed every day.

Magnetic Noise in Synchronous Machines

Transactions of the American Institute of Electrical Engineers, 1931
Magnetic noise in synchronous machines is shown to be of two principal kinds. One is a vibration in the tooth frequency range which usually occurs whether load is present or not; the other has twice line frequency and is dependent on load current. The vibrating part of the structure is usually the stator but may be the rotor and in nearly all cases of ...

Transient torques in synchronous machines

Electrical Engineering, 1933
The calculation of the alternating torque developed on single-phase short circuit has been discussed by previous authors.1,7 This paper extends the analysis of the electrical torque on short circuit to cover the transient torques due to losses, which although not so large as the alternating torques may be the most serious factor in the effects of short-

Dynamic Braking of Synchronous Machines

Transactions of the American Institute of Electrical Engineers, 1932
TWO GENERAL electrical methods of quickly stopping synchronous machines are plugging and dynamic braking. Plugging, consisting of reversing the phase rotation of the voltage applied to the armature winding, is subjected to a number of serious objections.
