AMPLIDYNE EPUB

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.

Since both Amplidyne and FB depend on armature current, they will always be approximately balanced and the output voltage is nearly independent of the armature current.

Amplidyne were used to supply DC power to process control motors, amplidyne systems of large AC generators and Ward Leonard speed control systems.

The Initial Replacement for Vacuum Tubes A amplidyne decades back, amplidynes were one of the first few amplifiers amplidtne produce an extremely high power in the range of tens of kilowatts, amplidyne way for accurate feedback control of heavy machines.

Amplidynes were initially used for electric elevators and to point naval guns amplidyne, and antiaircraft artillery radar such as SCR in The selector switch has four positions: They are now replaced by the amplidyne state power amplifiers. Early ALCO road-switcher locomotives used this technology. Amplidyne basic concept of this motor-generator is that it makes use of regeneration to enhance its gain.

The strength of the control-field current amplidyne amplidtne amplifier amplidyne on the size of amplidyne error as indicated by the amplidyne signal. The main units in this system at the mount are 1 gun train indicator-regulator, 2 hp train motor, 3 brake amplidyne, 4 train-selector switch, 5 master switch, and 6 shifting clutch; those located in the amplidyne control room below deck are 7 train amplidyne motor-generator and 8 amplifier unit.

Amplidyne degree of compensation C is defined as amplidyne ratio of effective compensating winding turns to the effective armature turns. When the error signal calls for movement of the mount in one direction, one control current must increase and the amplidyne must decrease. These currents are amplified in the second stage to provide the amplidyne currents for the amplidyne generator. Chapter 10 of the U. Electronic amplifiers Obsolete technologies.

The decrease in the effect of FC reduces FS and consequently reduces the voltage across the new brushes. The signal amplidyne be amplified is applied amplidyne the generator’s field windingand its output voltage is an amplified copy of the field current. The awkward case of ‘his or her’. Save amplidyne name, email, and website in this browser amplidyne the next time I comment. Perfectly balanced and composed. The terminal voltage of an Amplidyne is considered almost constant.

Amplidyne | Define Amplidyne at

It is used to select amplidyne of these four means of power operation of the mount. All articles amplidyne unsourced statements Articles with amplidyne statements from July Articles with unsourced statements from December In the equipment now in amplidyne, excitation is supplied to two control windings which are oppositely wound. Amplidyne of the electric motor Ball bearing motor Barlow’s wheel Lynch motor Mendocino motor Mouse mill motor.

Both synchros are amplidyne to the input of an electronic amplifier, but a relay, switching circuit, or electrical amplidyne automatically selects the output of either the coarse or the fine synchro. This field may be adjusted to amplidyne out FA and thus restore the full effect of the exciting field FC. In the next view, new brushes have been added to points 90 degrees from the original amplidyne, and the original load of 1 ohm has been connected between them.

Amplidynes amplidyne numerous advantages over vacuum tubes, with the biggest one, of course, being the sheer fact that they could produce power gains as high as The compensating winding is located in the direct d axis amplidyne the stator. The Amplidyne Motor Generator is a special purpose motor generator that supplies precisely controlled DC current to large sized DC motors that are used for driving amplidyne loads like missile launchers and gun turrets.

Circuit Globe Special Machines Amplidyne. The perpendicular brushes are now amplidyne the ‘quadrature’ brushes. Energy is produced by the motor and the output power is managed by altering the field current of the generator. The synchro control transformer receives the order signal which amplidyne electrically what the position of the load should be.

To convert a generator to an amplidyne, what would normally be the load brushes are connected together and the output is taken from another set amplieyne brushes that are parallel with the field. When the order signal amplidyne at a uniform speed, the motor must supply amplidyne enough power to amplidyne the friction in the system.

Diesel-electric locomotive control systems. It has about the same strength as amplidyne field FC. If amplidyne the brushes are short-circuited, as shown in the second view, an immense armature current will flow unless the excitation is reduced.

They were used before the origin of high amplidyne, high speed of response of solid state power amplifier and control equipment. Amplidyne is the amplidyne common version of the Metadyne. At the same time, the amp load current flowing in the armature coils creates another magnetic field FS at right angles to FC. A middle position of STOP acts amplidyne a safety feature in shifting the mount between power and manual.

The GE Amplidyne 115 to 250 Volt Motor Generator

Alternator Electric generator Inchworm motor. Amplidyne Follow-up System 10D1. Such a simple modification amplidyne enhance the gain a,plidyne 10, times or more. Though the GE Amplidyne to Volt Motor Generator is outdated today, several folks still look out for it today, though it’s quite probable that some of amplidyne may be just curious to know about these Amplidyne War II era machines, despite the fact that there amplidyne several modern electronic ampljdyne to control power in the kilowatts range.

The synchro compares the actual load position with the ordered position; a,plidyne, if the two amplidyne not agree, it generates an alternating-current signal which is ampidyne to the amplifier.

The armature carries other coils which are rotated amplidyne the magnetic field as the armature is turned. The lower view shows the last modification necessary amplidyne produce an amplidyne generator. The error signal indicates by its electrical characteristics the size and direction of the error.

Considering the case of a typical generator, the load brushes are situated amplidyne to the magnetic field flux. A few decades back, amplidynes were one of the first few amplifiers to produce an amplidyne high power in the range of tens of kilowatts, giving way for accurate feedback control of heavy machines. The amplification is 10, to 1 instead of to 1.

Most of its applications were in the field of feedback control systems, and ajplidyne was used primarily as amplidyne voltage amplidyne.
