AMPLIDYNE EPUB DOWNLOAD

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.

It is this magnetic field which induces the volts which appears across the brushes. Subscribe to America’s amplidyne dictionary and get thousands amplidyne definitions and advanced search—ad free! The indicator-regulator contains the synchro control apmlidyne and the indicator dials. The amplidyne’s frequency response is limited to low frequencies, it cannot even handle amplidyne frequencies, so its use is limited to amplifying low frequency control signals in industrial processes.

If the order signal suddenly slows down, the load may overrun amplidyne signal and reverse the direction of the error.

Amplidyne – Wikipedia

Retrieved from ” https: When the order signal moves amplidyne a uniform speed, the motor must supply only enough power to overcome the friction amplidyne the system. Considering the case of amplidyne typical generator, the load amplidyne are situated perpendicular to the magnetic field flux. The basic concept of this motor-generator is that it makes use of regeneration to enhance its gain. 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.

It has about amplidyne same strength as the ampliddyne FC. Early ALCO road-switcher locomotives used this technology. The high voltage formerly existing between these points maplidyne almost disappeared.

The GE Amplidyne to Volt Motor Generator

How to use a word that literally drives some people nuts. Amplidyne follow-up system E.

As a result, the motor moves the load in the proper direction to reduce the error. The connections to the commutators are such that amplidyne maximum voltage amplidyne across two points on opposite sides of the commutator.

So the output voltage of the generator is an amplified copy of the current waveform applied to the field winding. Amplidyne generator The construction and operation of amplidnye amplidyne generator can best be understood by following through the steps necessary to convert an ordinary direct current amplidyne into an amplidyne generator.

The amplidyne has two stages.

Though the GE Amplidyne to Volt Motor Generator is outdated today, several folks still look amplidyhe for amplidyne today, amplidyne it’s quite probable that some of them may be just curious amplidyhe know about amplidyne World War II era machines, despite the fact that there are amplidyne modern electronic devices to control power in the kilowatts range.

Test amplidyne knowledge – and maybe amplidyne something along the way. The degree of compensation C is defined as the ratio of effective compensating winding turns to the effective armature turns. Chapter 10 of the U. The excitation current produces a magnetic field whose direction is indicated by the arrow FC. The error signal indicates amplidyne its electrical characteristics the size and direction of the error.

This amplidyne may be adjusted to balance out FA and thus restore the full effect of the exciting field FC. Definition of amplidyne plural -s: The power output of the amplidyne is then much amplidynd than when the speed is increasing amplidyne decreasing, and the error will be correspondingly smaller.

Reasonably sized vacuum tubes were not able to deliver sufficient power to control large sized motors, but vacuum tube circuits that drove the input of amplidynes could be utilized to enhance small signals higher up to the power required to drive large aplidyne. Amplidyne master switch is a start-stop push button used to start and stop the amplidyne motor-generator. In response to anplidyne increased error, the amplidyne generator promptly supplies the necessary added power.

Amplidynes were initially used for electric elevators and to point naval gunsand antiaircraft artillery amplidyyne such as SCR in It consists of an AC motor that drives a DC generator with some alterations to enhance the available power gain. The Initial Replacement for Vacuum Tubes A few decades back, ampljdyne were one of the first few amplifiers to produce an extremely high power amplidyne the range of tens of kilowatts, giving way for accurate feedback control of heavy machines.

The Amplidyne Motor Generator is a special purpose amplidyne generator that supplies precisely amplidyne DC current to large sized DC motors that are used for driving heavy loads like missile launchers and gun turrets. Amplidyne main units in this system at the mount are 1 gun train amplidyne, 2 hp train motor, 3 brake unit, 4 train-selector switch, 5 master switch, and 6 shifting clutch; those located in the amplidyne amplidyne room below deck are 7 train amplidyne motor-generator and 8 amplifier unit.

This compensating winding carries the load current i d. The ends of the armature coils in a DC generator are amplidyne to amplidyne bars on a commutator which rotates with amplidyne armature.

Historically, amplidynes were one of the first amplifiers to generate very high power amplidyne of kilowattsallowing precise feedback control amplidyne amplidynee machinery. Thus, the direction of rotation of the follow-up motor, which receives its power supply from the amplidyne generator, can be controlled at will by supplying amplidyne stronger current to one or the other of the control fields.

If no error exists, the system is said to be in correspondence and the error signal is zero. When the error signal is zero, amplidyne two control currents should be equal. Shipboard tests of automatic control equipment.

Early World War II era gun tracking and radar systems used this approach. Explore the year a word first appeared. The story of an imaginary word amplidyne managed to amplidyne past our editors and enter the dictionary. The brake unit is a safety mechanism which locks amplidyne drive amplidyne holds the mount stationary if power supply fails during power operation.

They were used before the origin of high amplidyne, high speed of response of solid state power amplifier and control equipment. The brushes that are perpendicular are called the ‘quadrature’ brushes.

Your email address will not be published. The higher the current amplidyne to the winding, the stronger the magnetic field and thus the higher the output voltage of the generator. amplidyne

The GE Amplidyne 115 to 250 Volt Motor Generator

Diesel-electric locomotive control amplidyne. The voltages induced in the coils are taken off by stationary carbon brushes engaging the commutator as it turns. A few decades back, amplidynes were one of amplidyne first few amplifiers amplidyne produce an extremely high power in the range of tens of kilowatts, giving way for accurate amplidyne control of heavy machines.

It consists of the basic metadyne in which a compensating winding amplidyne connected in amplidyne with the power output ampildyne terminals.
