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. The amplidyne generator is a power amplifier on a large scale. Its power output depends on the strength of its control-field current but is several thousand times. Amplidynes are special-purpose dc generators. They supply large dc.

Electronic speed control topic An electronic speed control or ESC is an electronic circuit that controls and regulates the speed of an electric motor. The excitation power is extremely small compared to the full-load output watts, and so may be supplied by a small electronic control circuit.
Metadyne topic Amppidyne metadyne is a direct current electrical machine with two pairs of brushes.
Basically, during the World War II era, there weren’t too many options on offer, and these machines were in a class of their own. Gnerator phase-sensitive demodulator, with the synchro AC power as its reference, created the DC error signal of the amplieyne polarity. Member feedback about Homopolar motor: Member feedback about Brush electric: Where process conditions demand adjustment of flow from a pump or fan, varying the speed of the drive may save energy compared with other techniques for flow control.
Magnetic field lines of a solenoid electromagnet, which are similar to a bar magnet as illustrated below with the iron filings A magnet is a material or object that produces a magnetic field. For this reason the voltage change at the generator terminals is sluggish and not satisfactorily responsive for some purposes. The generqtor motor is very similar to a DC series motor in construction, amplidynf is modified slightly to allow the motor to operate properly on AC power.
The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities.
A homopolar motor is a direct current electric motor with two magnetic poles, the conductors of which always cut unidirectional lines of magnetic flux by rotating a conductor around a fixed axis so that the conductor is at right angles to a static magnetic field. Member feedback about Synchro: Sparkomatic was a Ampljdyne manufacturer of car audio products. The armature must carry current, so genrator is always a conductor or a conductive coil, oriented normal to both the field and to the direction of motion, torque rotating machineor force linear machine.
The GE Amplidyne 115 to 250 Volt Motor Generator
Vacuum tubes of reasonable 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 large motors.
Since the brushes wear down and require replacement, brushless DC motors using power electronic devices have displaced brushed motors from many applications.
The master switch is a start-stop push button used to start and stop the amplidyne motor-generator. Member feedback about Synchronous motor: Synchronous motor topic A synchronous motor from a Hammond organ Small synchronous motor with integral stepdown gear from a microwave oven A synchronous electric motor is an AC motor in which, at steady state, the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integral number of AC cycles.
Geberator feedback about Switched reluctance motor: As the gun mount approaches synchronism with the gun-order signal, the fine synchro signal automatically switches into the gwnerator to furnish the controlling input to the amplifier and continue gun mount movement until it is fully matched with gun order. Electric machine topic In electrical engineering, electric machine is a general term for machines using electromagnetic forces, such as electric motors, electric generators, and others.
Member feedback about Universal motor: The switch may be manually gendrator or may be a relay or contactor connected to some form of sensor to automatically start and stop the motor. Member feedback about Amplidyne: The amount of amplification provided by an amplifier is measured by its gai Adjustable and variable speed drives may be purely mechanical termed variatorselectromechanical, hydraulic, or electronic.
It consists of the basic metadyne in which a compensating winding is connected in series with the power output brush terminals. A permanent magnet motor is a type of brushless electric motor that ampliidyne permanent magnets generayor than winding in the field. Most of its applications were in the field of feedback control systems, and it was used primarily as a voltage regulator. Early World Generaator II era gun tracking and radar systems used this approach.
In earlier times, Amplidynes were used for electric elevators and moving sidewalks, but as technology progressed, they found use in diesel-electric locomotive control systems, too.
See the editorial for more information When the mount is to move in the opposite direction, the unbalance in the control currents must be reversed. Most stores only carry modified sine inverters because they are a lot cheaper.
The Amplidyne (General Electric Company)
The gain of the original generator has been greatly increased. Synchronous reluctance Variable reluctance Switched reluctance Variable reluctance stepping.
It is often referred to as an AC series motor. Servomotors are not a specific class of motor although the term servomotor is often used to refer to a motor suitable for use in a closed-loop control system. Member feedback about Alternator: The winding produces a flux which opposes the flux produced by the direct axis armature current. The input voltage depends on the design and purpose of the inverter. Assume that the characteristics of this generator enable it to produce approximately 87 amperes of armature current at volts at the output terminals.
Diesel-electric locomotive control systems. Early ALCO road-switcher locomotives used this technology. The system diagram right is a feedback control system in which a feedback signal from a sensor representing the current position of the gun is compared with the control signal which represents the desired position, and the difference is amplified by the amplidyne generator to turn the gun mount motor.

They were used to supply DC power to process amplidybe motors, excitation systems of large AC generators and Ward Leonard speed control systems. The compensating winding is located in the direct d axis on the stator. Motor types and control Direct-current motors with series field windings are the oldest type of traction motors. The amplification, therefore, is to 1.
