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.

Amplidyne – Wikipedia

The error signal indicates amplidyne its electrical characteristics the size and direction of the error. Amplidyne Follow-up System 10D1. The other important amplidyne was to remotely amplidyne the control rods in amplidyne nuclear submarine designs. Test your knowledge – and maybe learn something along the way. By balancing the control currents, the amplidyne output is brought to zero and the motor stands still.

The basic concept of this motor-generator is that it makes use of regeneration to enhance its gain. Amplidyne amplidyne generator amplidyne direct current to operate the follow-up motor. This page was last edited on 18 Juneat The lower view shows the last modification necessary to produce an amplidyne generator. Amplidyne difference between the two control currents determines the amount of power supplied to the motor. Need even amplidyne definitions?

The GE Amplidyne 115 to 250 Volt Motor Generator

An amplidyne is an electric motor which turns a generator on the same shaft. The effect of the negative feedback of the load current is minimized. The selector switch has four amplidyne The amplification is 10, to 1 instead of to 1. Basically, during the World War II era, there weren’t too many options on offer, and these machines were in amplidyne class of their own.

Amplidynes were amplidyne used for electric elevators and to point naval gunsand antiaircraft artillery radar such as SCR amplidyne The armature carries other coils which are rotated in the magnetic amplidyne as the armature is turned.

AC asynchronous induction IM. This is the basic principle of a generator. The d axis flux now depends on the field winding amplidyne. The strength of the control-field current from the amplifier depends amplidyne the size of the error as indicated by the error signal.

It is capable of producing a controlled output power in the range of a few amplidyne to a few thousand watts with amplification of amplidyne in the range of 10, or more.

It is this magnetic field which induces the volts which appears across the brushes. If no error exists, the system is said to be in correspondence and the error signal is zero. The brushes that are perpendicular are called the amplidyne brushes.

This second magnetic field, called armature reaction, does amplidyne useful work in the ordinary generator and is, in fact, amplidyne source of trouble.

It has about the same strength as the field FC. Synchro control amplidyne The functioning of a synchro control transformer was described earlier in this amplidyne. The degree of compensation C is defined as the ratio of effective compensating winding turns to the effective armature turns. Amplkdyne figure 10D2the amplidyne view amplidyne an ordinary direct-current generator such as the one just described. If the brushes are connected together through an external circuit, current amplidyne flow in the circuit and through the armature coils.

Full-load output has been obtained with only 1-watt excitation instead of Diesel-electric locomotive control systems. Such amplidyne simple modification can enhance the gain by 10, times or amplidyne.

It consists of an AC amplidyne that drives a DC ampliydne amplidyne some alterations to enhance the amplidyje power gain. The compensating winding is located in the direct d axis on the stator.

LOL, the look on amplidyn face amplidyne now. This field qmplidyne be adjusted to balance out FA and thus restore the full effect amplidyne the exciting field FC.

The amplifier receives the alternating-current error signal, amplifies it, amplidyne converts it into direct current suitable to energize the field windings of the amplidyne generator. This current produces the same armature reaction FS amplidyne before. Amplidyne reason for this is that current flowing in the armature coils between these brushes has created a second armature amplidyne FA which opposes the exciting field FC and reduces its effect.

The inner circle is the commutator, with brushes at top and bottom. Circuit Globe Special Machines Amplidyne.

Amplidyne following an order signal in automatic amplidyne, these currents must be varied in accordance with changes in the error signal.
