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 gun tracking and radar systems that were used during World War II made use of this approach, and geenrator GE Amplidyne motor generator was one such machine. amplidyne generator
The Amplidyne (General Electric Company)
The amplifier receives amplidynne alternating-current error signal, amplifies it, and converts it into direct current suitable to energize the field windings of the amplidyne generator. Later on, they were applicable for controlling processes in steelworks.
It is meant to strengthen the idea that with the amplidyne generator, something large and heavy can be controlled very precisely by something very small, almost insignificant.
They are now replaced by the solid state power amplifiers. Because of the amplidyne’s ability to amplify, its output can be used to drive a powerful motor, which turns the heavy object antenna. The effect of the negative feedback of the load current is minimized. AC motor DC motor.
It has about the same strength as the field FC. The excitation current produces a magnetic field whose direction is indicated by the arrow FC. If you want to convert a generator to an amplidyne, you will have to connect what seems to be the load brushes jointly and get the output from another set of ampludyne brushes amplidyne generator to the field. The amplidyne generator of the original generator has been greatly increased.
Amplidyne generator The construction and operation of the amplidyne amplidyne generator can best be understood by following through the steps necessary to convert an ordinary direct current generator into an amplidyne generator.
Other refinements amplidyne generator necessary to produce the fast, stable amplidyne generator necessary in a follow-up system, but the machine shown in the lower view of figure 10D2 is the basic form of all amplidyne generators.
Its power output depends on the strength of its control-field current but is several thousand times greater. Unlike an ordinary motor-generatorthe amplidyne generator of an amplidyne is not to generate amplidyne generator steady voltage but to generate a voltage proportional to an input current, to amplify the input. As a result, the motor moves the load in the proper direction to reduce the error. The armature carries other coils which amplidyne generator rotated in the magnetic field as the armature is turned.
Vacuum tubes of amplidyne generator size were unable to deliver enough power to control large motors, but vacuum tube circuits driving the input of an amplidyne could be used to boost small signals up to the power needed to drive amplidyne generator motors. It is now mostly obsolete.
The motor provides the power, turning the generator at a constant speed, and the signal to be amplified is applied to the generator’s field winding.
This generator is assumed to be amplidyne generator kw machine 10, watts outputand the excitation required is about watts. Doubly-fed Linear Servomotor Stepper Traction.
The amplification is 10, to amplidyne generator instead of to 1. Early World War II era gun tracking and radar systems used this approach. Assume that the characteristics of this generator enable it to produce approximately 87 amperes of armature current at volts at amplidyne generator output terminals. For instance, in a normal dc generator, a small dc voltage applied to the field windings is able to control the output of the generator.
A middle position of STOP acts as a safety feature in shifting the amplidyne generator between power and manual. The indicator-regulator contains the synchro control transformer and the indicator dials.

These currents are amplified in the second stage to provide the control-field currents for the amplidyne generator. The following changes, for explanation purposes, will convert the typical dc generator above into an amplidyne generator. The amplifier has amplidyne generator stages. This simple change can increase the gain by a factor of 10, or geneator.
Amplidyne is the most common amplidyne generator genertor the Metadyne. If the 3 volts applied to the field winding is considered an input, and the volts taken from the brushes is an output, there is a gain of Because of the very amplidyne generator resistance in the armature circuit, a much lower control-field flux produces full-load armature current full-load current in the armature is still about 87 amperes.
