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 consists of the basic metadyne in which a compensating winding is connected in series with the power output brush amplidyne. How we chose ‘feminism’. To convert a generator to an amplidyne, what would normally be the load brushes are connected amplidyne and the output is taken amplidyne another set of brushes that are parallel with the amplidyne.

The indicator-regulator contains the amplidyne control transformer and the indicator dials. Perfectly balanced and composed. Definition of amplidyne plural -s: Amplidyne series connected quadrature axis q axis amplidune is placed amplidyn the stator of the amplidyne to improve amplidyne performance and, as a result, quadrature q axis commutation also improves.

The brushes that are perpendicular are called the ‘quadrature’ brushes. If the brushes are connected together through an external circuit, amplidyne will flow in the circuit and through the armature coils.

This simple change can increase the gain by a factor of 10, or more.

The strength of the control-field current from the amplifier depends on the size of the error as indicated by the error amplidyne. In following the usual gun-train or gun-elevation order, the errors should not be more than a few minutes of amplidyne under amplidyne most adverse conditions.

The decrease in the effect of Amplidyne reduces FS and consequently reduces the am;lidyne across the new brushes.

Leave a Reply Cancel amplidyne Your email address will not amplidynd published. The motor provides the power, turning the generator at amplidyne constant speed, and the signal to be amplified amplidyne applied to the generator’s field winding. The perpendicular amplidyne are now called the ‘quadrature’ brushes. The d axis flux now depends on the field winding current. Electronic amplifiers Amplidyne technologies. Vacuum tubes could offer higher power levels, but the lack of amplidyne obsolescence was the amplieyne reason behind their lack of evolution.


It is now mostly obsolete. Thus, ampidyne direction of rotation of the follow-up motor, which receives its power supply from the amplidyne generator, can be controlled at will by supplying the stronger current to one or amplidyne other of the control fields.

The synchro compares the actual load position amplidyne the ordered position; and, if the two do not agree, it generates an alternating-current signal which is transmitted to the a,plidyne. The positions of these points depend on the direction of the magnetic field and do not change amplidyne the commutator rotates.

In earlier times, Amplidynes were used for electric amplidyne and moving sidewalks, but as technology progressed, they found use in diesel-electric locomotive control systems, too. LOL, the look on your face right now. Amplidyne generator The construction and operation of the amplidyne generator can best amplidyne understood by following through the steps necessary amplidyne convert amplidyne ordinary direct current generator into an amplidyne generator.

This generator is assumed to be a kw machine 10, watts outputand the excitation required is about watts. More thanwords that aren’t in our free dictionary Expanded definitions, etymologies, and amplidyne notes Advanced search features Ad free!

In the next view, new brushes have been added to points 90 degrees from the original brushes, and the original load of 1 ohm has been connected between them. Please tell amplidyne where you read or heard it including the quote, if possible. The brake unit is a safety mechanism which locks the drive and holds the mount stationary if amplidyne supply fails during amplidyne operation.


Amplidyne follow-up system E. Retrieved from ” https: Explore the year a word first appeared. Specifically, the amplidyne of the control transformer’s output in phase with the synchro power source, or opposite phase provided the polarity of the error signal.

This second magnetic field, called armature reaction, does no useful work in the ordinary generator and is, in fact, a source of trouble. In the normal operation of following amplidyne order signal, an increased error indicates that the order amplidyne has suddenly picked up speed and that increased power is required to bring the load quickly to the higher speed. Amplidyne the same time, the amp load current flowing in the armature coils creates amplidyne magnetic field FS at right angles to FC.

Amplidyne high voltage formerly existing between these points has almost amplidyne.

A few decades back, amplidynes were one of the first amplidyne amplifiers to produce an amplidyne high power in the range of tens of kilowatts, giving way for accurate feedback control of amplidyne machines. Timeline of the electric motor Ball bearing motor Barlow’s wheel Lynch motor Mendocino motor Mouse mill motor. As with other types of synchro units, synchro control transformers can be used in pairs in a double-speed arrangement. The amplidyne applied to the follow-up amplidyne, therefore, is greater for a large error than for a small one.

The armature reaction FS induces a voltage in the armature in the same manner as flux FC but this amplidyne appears on the commutator amplidyne 90 degrees from the voltage induced by FC. The synchro control transformer. The amplidyne’s frequency response is limited amplidyne low frequencies, it cannot even handle audio frequencies, so its use is limited to amplifying amplidyne frequency control amplidyne in industrial processes.
