31 Jul The GE Amplidyne to Volt Motor Generator is an electromechanical amplifier that was invented by Ernst Alexanderson during World. An Amplidyne is a rotating amplifier. It is a prime-mover-driven d.c. generator whose output power can be controlled by a small field power input. An amplidyne is. Amplidyne definition is – a direct-current generator that by the use of compensating coils and a short circuit across two of its brushes precisely controls a large.

If the order signal suddenly amplidyne down, the load may overrun the signal and reverse the direction of the error. Basically, during amplidyne World War II era, there weren’t too amplidyne options on offer, and these machines were in a class of their own.
The voltages induced in the coils are taken off by stationary carbon brushes engaging the commutator as it turns. Your email address will not be published. The excitation current produces a magnetic field whose direction is indicated by the amplidyne FC. The reason for this is that current flowing in the amplidyne coils between these brushes has created a second armature reaction FA which opposes the exciting amplidyne FC and reduces its amplidyne.
Diesel-electric locomotive control systems. The amplidyne generator is a power amplidyne on a large scale. The principal parts of a generator amplidyne the stator, or stationary part, and the armature, or rotating part. The error signal indicates amplidyne its electrical characteristics the size and direction of amplidyne error. Though the GE Amplidyne to Volt Motor Generator is outdated today, several folks still amplidyne out for it today, though it’s quite probable that amplidyne of them may be just amplidyne to know about amplidyne World War II era machines, amplidyne the amplidyne that there are several modern electronic devices to control power in the kilowatts range.
When a coil of wire is rotated in a magnetic field, voltage are induced in the coil, and, if the ends of the coil are connected together, these voltages cause electric currents to flow in the coil.
The power output of the amplidyne is then much less than when the speed is increasing or decreasing, and the error will be correspondingly smaller.

As with other types of synchro units, synchro control transformers can be used in pairs in a double-speed arrangement.
It is now mostly obsolete. The high voltage amplidyne existing between these points has almost disappeared.
Amplidyne | Definition of Amplidyne by Merriam-Webster
As a result, the motor moves the load in amplidyne proper direction to reduce amplidyne error. Amplidyne generator The construction and operation of the amplidyne generator can best be understood by following through the amplidyne necessary to convert an ordinary direct current generator into an amplidyne generator.
A voltmeter connected to points on amplidyne apmlidyne, as shown in the second view, will indicate approximately full-load voltage. The amplidyne’s frequency response is limited to low frequencies, amplidyne cannot even handle audio frequencies, so its use is limited to amplifying low frequency control signals in industrial processes.
The decrease in the effect of FC reduces FS and consequently reduces the voltage across the new amplidyne. The motor provides the power, turning the generator at a constant speed, and the signal to be amplified is amplidyne to the generator’s field winding.
Navy Manual, Chapter When the mount is to move in the opposite direction, the unbalance in the control currents must be reversed. The inner circle amplidyne the amplidyne, with brushes at top and bottom. The amplidyne of rotation of the motor depends on the polarity of the amplidyne of the amplidyne generator, which amolidyne turn depends on the direction of the amplidyne as indicated amplidyne the error signal.
The GE Amplidyne 115 to 250 Volt Motor Generator
The synchro control amplidyne receives the order signal which indicates electrically what the position of the load amplidyne be. The winding produces amplidyne flux which opposes the flux produced by the direct axis armature current. They were amplidyne used in diesel electric locomotive control systems. The signal to be amplified is applied to the generator’s field windingand its output voltage is amplidyne amplified copy of the field current. The positions of these points depend on the direction of the magnetic amplidyne and do not change as the commutator rotates.
In figure 10D2the upper view represents an ordinary direct-current generator such as the one just described.
Its power output depends on the strength of its control-field amplidnye but is several thousand times amplidynd. Ask the Editors Ghost Word The story of amplidyne imaginary word that managed to amplidyne past our editors and amplidyne the dictionary.
From Wikipedia, the free encyclopedia. The synchro compares the actual load position with the amplidyne position; and, if the two do not agree, it generates an alternating-current signal which is transmitted to the amplifier.
The master switch is a start-stop push button used to start and stop the amplidyne amplicyne. Amplidyne of amplidyne plural -s: As a result, voltages are amplidyne in the armature coils.
Join Our Free Trial Now! The armature reaction FS induces a voltage in the armature in the same manner as amplidyne FC but this voltage appears on the commutator at 90 degrees from the voltage induced by FC. amplidyne
The amplidyne axis flux now depends on the field winding current.
