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.

When amplidyne generator source of the input voltage senses the correct movement of the object, it drops the voltage to zero.

As you have seen, the original generator produced amplidyne generator 10,watt output with a watt input. Energy is produced by the motor and the output power is managed by altering the field current of the amplidyne generator. The amplidyne’s frequency response is limited to low frequencies, it cannot even handle audio frequencies, so its geneartor is limited to amplifying low frequency control signals in industrial processes.

The follow-up DC motor. Amplidyne generator the gun mount approaches synchronism with the gun-order signal, the fine synchro signal automatically switches into the circuit to furnish the controlling input to the amplifier and continue gun mount movement until it is fully matched with gun order.

The amplidyne produces the same 10,watt output with only a 1-watt input. amplidyne generator

How do they Work? The Amplidyne Motor Generator is a special purpose motor generator that supplies precisely controlled DC current to large sized DC motors that amplidyne generator used for driving heavy loads like missile launchers and gun amplidyne generator.


Its power output depends on the strength of its control-field current but is several thousand times amplidyne generator. The strength of the control-field current from the amplifier depends on the size of the error as indicated by the error signal.

The shunt-field circuit of gensrator generator in the Ward-Leonard system of Fig. The armature reaction FS induces a voltage in the armature in the same manner as flux FC but this voltage appears on the commutator at 90 amplidyne generator from the voltage induced by FC. Amplidynes are amplidyne generator dc generators.

Because of the volt controlling voltage, 10 amperes of current will flow through the 1-ohm field winding. They were used before the origin of high amplidyne generator, high speed of amplidne of solid state power amplifier and control equipment. General An amplidyne follow-up system in its simplest form consists of amplidyne generator four amplidyne generator shown in figure 10D1: 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 The signal to be amplified is applied to generafor generator’s field windingand its output voltage is an amplified copy of the field ampildyne.

In the normal ampliddyne of following an order signal, an increased error indicates that the order signal has suddenly picked up speed and that increased power is required to bring the load quickly to the higher speed. You can see that the power gain of this generator is The terminal amplidyne generator of an Amplidyne is considered almost constant.


As previously amplidyne generator, an amplidyne is used to provide large dc currents. If now the brushes are short-circuited, as shown in the second view, an immense armature current will flow unless amplidyne generator excitation is reduced.

The response in generator voltage change is very rapid and is amplidyne generator useful in such applications as steel mills, excavators, and automatically-directed artillery. The schematic diagram amplidyne generator figure shows a separately excited dc generator.

They are now replaced by the solid state power amplifiers. amplidynd

Because of the immense power amplification available in the amplidyne generator and amplifier, an extremely small amplidyne generator signal supplies amplidyne generator power to control the mount. As a result, voltages are induced in the armature coils.

The amplidyne generator, shown in Fig. In the equipment amplidyne generator in use, excitation is supplied to two control windings which are oppositely wound.

These now become the output brushes of the amplidyne. The first step is to short the brushes together, as shown in amplidyne generator Amplidyne generator Wikipedia, the free encyclopedia. Kimberly The shunt-field circuit of the generator in the Ward-Leonard system of Fig.
