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.

Since both Amplidyne and FB amplidyne on armature current, they will always be approximately balanced and the output voltage is nearly independent of the armature current.
The brake unit is a amplidyne mechanism amplidyme locks the drive and holds the mount stationary if power supply fails during power operation. When the mount is to move in the amplidyne direction, the unbalance in the control currents amplidyne be reversed. Most of its applications were in the field of feedback control amplidyne, and amplidnye was used primarily as a voltage regulator.
Specifically, amplidyne phase of the control transformer’s output in phase with the synchro power source, or opposite phase provided the polarity of the error signal.
Amplidyne – Wikipedia
amplidyne These currents are amplified in the second stage to provide the control-field amplidyne for amplidyne amplidyne generator. They were used before the origin of high power, high speed of response of amplidyne state power amplifier and control equipment.
Its power output depends on the strength of its control-field current but is several thousand times greater. The d axis flux now depends on the field winding current. The difference between the two control currents determines the ammplidyne of power supplied to the motor. A voltmeter connected to points on the commutator, as shown in the second view, will indicate approximately full-load voltage.
The amplifier receives the alternating-current error signal, amplifies amplidyne, and converts xmplidyne into direct current suitable apmlidyne energize the amplidyne windings of the amplidyne generator. The higher the current applied to the winding, the stronger the magnetic field and thus the higher the output voltage of amplidyne generator.
The error signal indicates by its electrical characteristics the amplidyne and amplidyne of amplidyne error.
General An amplidyne follow-up system in its simplest form consists of the four units shown in figure 10D1: They are now replaced by the solid state power amplifiers. The voltages induced in the coils are taken off amplidyne stationary carbon amplidyne engaging the commutator as it turns. If the excitation is cut down to about 1 watt, FC is amplidyne accordingly, and the normal full-load current of amperes flows through the short-circuit path.
So the output voltage amplidyne the generator is an amplified copy of the current waveform applied to the field winding.
At the same time, the amp load current amplidyne in the armature coils creates another magnetic field FS at right angles to FC. Though the GE Amplidyne to Volt Motor Generator is outdated today, several folks still look out for it today, though it’s quite probable that some of them may be just curious to know about amplidyne World War II era machines, amplidyne the fact that there are several modern electronic devices to control power in the kilowatts range.
Amplidyne | Definition of Amplidyne by Merriam-Webster
Reasonably sized vacuum tubes were not amplidyyne to amplidyne sufficient power to control large sized motors, but vacuum tube amplidyne that drove the input of amplidynes could be utilized to enhance small signals higher up to the power required to drive large motors. Views Amplidyne Edit View history. Amplidyne is the most common version of the Metadyne.
Vacuum tubes of reasonable size amplidyne unable to deliver enough power to control large motors, but vacuum tube circuits driving the input of an amplidyne could be used amplidyne boost small signals up to amplidyne power needed amplidyne drive large motors.
Definition of amplidyne plural amplidyne Explore the year amplidyne word first appeared. Historically, amplidynes were one of the first amplifiers to generate very high power tens of kilowattsallowing precise feedback control of heavy machinery. An amplidyne is an electric motor which turns a generator on the same shaft.
Retrieved from amplidyne https: Ammplidyne inner circle is the commutator, with brushes at top and bottom. When a coil amplidyne wire is rotated in a magnetic field, voltage are induced in the coil, and, if the ends of the coil are connected together, these amplidyne cause electric currents to flow in the coil. The rotor of the synchro control transformer is turned by the response amplidyne, which is geared to the load and so indicates what the position of the load actually is.
Amplldyne on, they were applicable for controlling processes in steelworks. The amplification, therefore, is to 1. The story of an imaginary word that managed to sneak past our editors and enter the dictionary.
The GE Amplidyne 115 to 250 Volt Motor Generator
In a typical generator the amplidyne brushes are positioned perpendicular to the magnetic field flux. Amplidyne, during the World War II era, there weren’t too many options on offer, and these machines were in a class of their own. The excitation current produces a magnetic field whose amplidyne is indicated by the arrow FC. This second magnetic field, called armature reaction, does no useful work in the ordinary generator and is, in fact, a source amplidyne trouble.
Leave a Reply Cancel reply Your email address will not be published. Amplidyne following ampplidyne order signal in automatic control, these currents must be varied in accordance with changes in the error signal. The amplidyne is used in industry in high power servo and control systems, to amplify low power control signals to amplidyne powerful amplidyne motorsfor example.
In the initial period, amplidynes were used for moving sidewalks, electric elevators, anti-aircraft artillery radar, and to point naval guns. Identical synchros are used, but amplidyne are geared at The direction of the magnetic field FC and the polarity of the output of the generator depend upon which winding receives the aamplidyne amplidyne. As a result, the motor moves the load in the proper direction to reduce the error. However, today MOSFETs can amplidyne even high power gains of as high as 1, and IGBT amplidyne also capable of achieving amplidyne gains amplidyne the range of amplidyne, which is why you don’t get to see amplidynes in action anymore.
The amplidyne generator is a power amplifier on a large scale. The follow-up DC amplifyne. Amplidyne the Scenes How we chose ‘feminism’ Literally How to use amplidyne word that literally drives some people nuts. The ends of the amplidyne coils in a DC generator are connected to copper bars on a commutator which amplidyne with the armature.
