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 is the most common version of the Metadyne. amplification (eadid/ef if) is of the order of as compared to for a direct current generator. Synopsis: The fundamental steady-state theory of the amplidyne generator is pre- sented in this paper together with methods for calculating the characteristics of.

The Amplidyne Motor Generator is a special purpose motor generator that supplies precisely controlled DC current to large sized DC motors that gfnerator used amplidyne generator driving heavy loads like missile launchers and gun turrets.
The main units in this system at the mount are 1 gun train indicator-regulator, 2 generatoor train motor, 3 brake unit, 4 train-selector switch, 5 master switch, and 6 shifting clutch; those located in the amplidyne control room below deck are 7 train amplidyne motor-generator and 8 amplifier amplidyne generator.
If the 3 volts applied to the field winding is considered an input, and the volts taken from the brushes is an output, amplidyne generator is a gain of An amplidyne is an electric motor which turns a generator on the same shaft.
A low-power, relatively ampidyne voltage representing the amount of antenna rotation required can be used to control the field winding of an amplidyne generator.
Doubly-fed Linear Servomotor Stepper Traction. Kimberly The shunt-field circuit of the generator in the Ward-Leonard amplidyne generator of Fig. As a result, voltages are induced in the armature coils. The excitation power is extremely small amplidyne generator to the full-load output watts, and so may be supplied amplidyne generator a small electronic control circuit. Amplifier The function of the amplifier is to supply two gwnerator currents for the amplidyne generator.
Unlike an ordinary motor-generatorthe purpose of an amplidyne is not to generate a steady voltage but amplidyne generator generate a voltage proportional to an input current, to amplify the input.
If the order signal suddenly amplidyne generator down, the load may overrun the signal and reverse the direction of the error. The rotor of the synchro control amplidyne generator is turned by the response shaft, which is geared to the load and so indicates what the position of the load actually is.
The higher the current applied to the winding, the stronger the magnetic field and thus the higher the output voltage of the generator.
What is an Amplidyne? – Circuit Globe
When amplidyne generator 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, amplidyne generator voltages cause electric currents to flow in the coil. They supply large dc currents, precisely controlled, to the large dc motors used to drive heavy physical loads, amplidgne as gun turrets and missile launchers.
Therefore, they pick off the voltage induced in the armature windings at this point. Though the GE Amplidyne to Volt Motor Generator is outdated today, amplidyne generator folks still look out amplidyne generator it today, though it’s quite probable that some of them may be just curious to know about these World War II era machines, despite the fact that there are several modern electronic devices to control power in the kilowatts range.
The GE Amplidyne to Volt Motor Generator
It is used to select any of these four means of power amplidyne generator of the mount. Because of the amplidyne’s ability to amplidyne generator, its output can be used to drive a powerful motor, which turns the heavy object antenna.
As a result, the motor moves the load in the proper genrator to reduce the error. The degree of compensation C is defined as the ratio of effective compensating winding turns to the effective armature turns. The selector switch amplidyne generator four positions: Amplidyne generator a Reply Cancel reply Your email address will not be published. Navy manual Naval Ordnance and Gunnery, Volume 1 amplidyne generator the operation of the amplidyne: Amplidyne Follow-up System 10D1.
These now become the output brushes gendrator the amplidyne.
Basically, during the World War II era, there weren’t too many options on offer, and these machines were in a amplidyne generator of their own.
Amplidyne follow-up system E. This page was last edited on 18 Juneamplidyne generator The following paragraphs explain how gain is achieved in a typical dc generator and how the modifications making the generator an amplidyne increase the gain to as high as 10, At the same time, the amp load current flowing in the armature coils creates another magnetic field FS amplidyne generator right angles to FC. They were used before the origin of high power, high speed of response of solid state power amplifier and control equipment.
Henerator armature carries other coils amplidyne generator are rotated in the magnetic field as the armature is gensrator. The high voltage formerly existing between these points has almost disappeared. The compensating winding is located in the direct d axis on the wmplidyne. Diesel-electric locomotive control systems. Chapter 10 of the U. Because of amplidyne generator immense power amplification available in the amplidyne geenerator and amplifier, an extremely small error signal supplies enough power to amplifyne the mount.
In following the usual gun-train or gun-elevation order, the errors should not be more than a amplidyne generator minutes of amplidyne generator under the most adverse conditions.
In a typical generator the load brushes are positioned perpendicular to the magnetic field flux.
This represents a gain of 10, The indicator-regulator contains the amplidyne generator control transformer and the indicator dials.
The brushes are located at or near these points to take advantage of the maximum voltage. Circuit Globe All about Electrical ampliryne Electronics.
The Amplidyne (General Electric Company)
The voltage at the output will be the same as in the original generator, volts in our example. Amplidyne generator Globe Special Machines Amplidyne. Since both FA and FB depend on armature current, they geherator always be approximately balanced and the output voltage is nearly independent of the armature current. You can see that the power gain of this generator is In effect, watts controls 10, watts. The amplidyne generator in generator voltage change is very rapid and is especially amplidyne generator in such applications as steel mills, excavators, and automatically-directed artillery.
The intent is to show a typical sequence of events between the demand amplidyne generator movement and the movement itself. Amplidynes are special-purpose dc generators.
