Does the voltage output increase when a generator is made to spin faster?

You would have to apply a higher voltage from outside - for example, in the case of DC, connect a battery that provides more voltage, or connect more than one battery in series; or in the case of AC, use a transformer to increase the voltage.

What is the off load voltage of the generator?
Terminal voltage is the voltage between the output terminals of a generator.
When you rotate the handle of the electric generator faster does it deliver more less or the same voltage?
The speed of a generator only effects the frequency. Most generators operate at 1800 RPM. The output voltage is controlled by varying the field excitation voltage.
What limits the output of an electrical generator?
The amount of voltage of an electrical generator will determine the limit of the output of energy. If the voltage is too high, it can burst the pipes causing it to shut down.
How variable speed generator works and its specification?
First you have to understand how a generator works. Basically the excitation voltage is what varies according to generator output. Usually on a power source that has a inconsistant rpm, the excitation voltage will vary similar to a govenor in order to hold the generator output constant.
How does a generator exciter work?
Exciter controls the magnetic field in the generator system and controls the output voltage and/or current.
How does the load affect voltage output of a series generator?
In a series generator, as load is added, output voltage increases.
What is the off load voltage of the generator?
Terminal voltage is the voltage between the output terminals of a generator.
What is meant by regulation or an alternator?
Regulation of an alternator is varying or adjusting the d.c. current flow (excitation current) in the revolving field coil to control the output voltage. When an alternator is subject to varying load conditions, and therefore changing load resistance at the output, the output voltage will vary in response. When output voltage is reduced in response to increased load (reduced output resistance), the "voltage regulator" will respond by increasing the excitation current to increase the voltage output. If load is reduced, the generator will momentarily become over-excited and the ouput voltage will increase. The voltage regulator responds by decreasing excitation current, returning the generator output voltage to its nominal level.

The speed of a generator only effects the frequency. Most generators operate at 1800 RPM. The output voltage is controlled by varying the field excitation voltage.
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.
How do you raise voltage in generator?
Increasing the field current will boost the generator output voltage, assuming the governor doesn't limit.
Advantages and disadvatages of a self excited induction generator?
The main disadvantage should be obvious - when the output voltage of the generator is used to provide field current to the generator....what happens if the output voltage sags? If the output voltage becomes depressed, the output power of the generator is compromised (becomes less and less), this in turn can cause the output to become more depressed, leading to an incrementally decreasing output capability. The main advantage is cost savings.
What limits the output of an electrical generator?
The amount of voltage of an electrical generator will determine the limit of the output of energy. If the voltage is too high, it can burst the pipes causing it to shut down.
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 happens to the output in terms of real power of a generator when you change the voltage and frequency say from 220v 50Hz to 110v 60Hz?
The voltage and frequency ARE the output of the generator. If you change the fuel to the generator, it will change speed, and the voltage will change. Less fuel = less speed = lower frequency = lower voltage.
Is it possible to turn a 2.7kva Honda generator into a welder generator?
No, the output voltage is too high.
What is a reversing relay?
A reverse current relay prevents a generator from discharging the battery when generator output is less than battery voltage. When generator output is greater than battery voltage, the reverse current relay closes and connects generator to electrical bus.
