How field current change in 'V and inverted v curves ' of synchronous motor?
In v curves armature current decreases in under excitation and increase in overexcitation as fielcurrent increases and armature current is maximum at unity power factor.The power is maximum when load angle is equal to impedance angle.A linear motor is a essentially a multi phase
What are internal combustion power plant?
The power plant includes an internal combustion engine and a direct current electric motor generator.
What motors is used in railway engines for traction?
dc series motor :A series-wound DC motor has a low resistance field and armature circuit. Because of this, when voltage is applied to it, the current is high. (Ohms Law: current = voltage/resistance). The advantage of high current is that the magnetic fields inside the motor are strong, producing high torque (turning force), so it is ideal for starting a train. The disadvantage is that the current flowing into the motor has to be limited, otherwise the supply could be overloaded and/or the motor and its cabling could be damaged.
What is difference between line current and phase current?
A phase current is the current passing through a phase, whereas a line current is the current flowing through a line.In the case of a balanced delta-connected load, IL = 1.732 IP. In the case of a balanced star-connected load, IL = IP.For unbalanced loads, these relationships don't hold true, and must be individually calculated.
What is a syncronous condenser?
A synchronous condenser is physically an electric generator/motor without a mechanical power source. Electrically a synchronous condenser changes the timing between rise and fall of current compared to voltage (phase angle). They also use stored energy to smooth small power fluctuations.

What kind of current flows in the armature conductor of a dc generator?
pogi current flow in the armature conductor
Armature reaction in a DC generator?
ARMATURE REACTION in DC MachineAll current-carrying conductors produce magnetic fields. The magnetic field produced by current in the armature of a dc generator affects the flux pattern and distorts the main field. This distortion causes a shift in the neutral plane, which affects commutation. This change in the neutral plane and the reaction of the magnetic field is called armature reaction.
What is a shunt generator?
A shunt generator is a method of generating electricity in which field winding and armature winding are connected in parallel, and in which the armature supplies both the load current and the field current.A direct current (DC) generator, not using a permanent magnet, requires a DC field current. The field may be separately excited by a source of DC, or may be connected to the armature of the generator so that the generator also provides the energy required for the field current.
What is the excitation system in a generator used for?
The excitation system is used to control the excitation of the rotating field in the armature. By increasing the armature current, it in turn increases the magnetic flux in the armature coil. This has the effect of increasing the voltage output of the generator. By lowering the armature current this in turn lowers the generator output voltage. The generator's voltage regulator automatically adjusts the output voltage continuously as the applied load on the generator changes.
What are the effect of armature reaction in DC machine and how the armature reaction is minimise?
Armature reaction is the interaction between the magnetic flux produced by armature current and that of the main magnetic field in an electric motor or generator.
What will happen to the generator voltage when the load fluctuates in distribution board?
The generator's voltage regulator will sense the fluctuation. If the voltage goes low more current will be applied to the armature to compensate. If the voltage goes high less current will be applied to the armature to compensate.
What are the parts of a direct current generator?
there are many parts of a dc generator armature, field coil, yoke, body, rotor and commutator.
How is alternating current produced in a generator?
In an AC generator an armature is rotated in a magnetic field. This induces an electric current in the armature. if you want more look on the bottom. As the crank turns the armature rotates in the magnetic field. One side of the armature moves up, and the other side moves down. The up and down motion induces a current in the wire. The current is in opposite directions on two sides of the armature. After the armature turns halfway, each side of it reverses direction in the magnetic field. The side that moved up moves down, vice versa. The current is induced. As the Armature turns, slip rings turn with it. They are attached to the ends of the armature. As they turn, they make contact with the brushes. The brushes can be connected to the rest of the circuit. In this way, a generator becomes energy source.
What is a Generator consisting of a coil that rotates between the electromagnet causing a current to flow in the armature?
dynamo
What is an armature made of?
The armature is the part of an electric generator or motor that contains the main current-carrying winding. It usually consists of a coil of copper wire that is wound around an iron or steel core. The coil and core are placed in a magnetic field, which is produced by one or more permanent magnets or electromagnets.
How does a voltage regulator regulate the voltage output of an ac generator?
Generator output is controlled by voltage feedback to the voltage regulator which senses voltage drop or rise and regulates the current being sent to the armature. This rise and fall of the armature current governs the generators output voltage.
