One factor to consider in the generation of power is that in a generator there is an electromagnetic field moving past wires in which a voltage is induced. If the speed is reduced (speed is propotional to frequency) the voltage will be too, all else being equal. However there may be compensation for this by a rise in exitation current to increase the magnetic field seen by the wires.
Other equipment outside the generator can also control the voltage received.

How do you change the speed of motor without change pole and frequency?
On an AC motor you basically vary the frequency on a DC you can vary the voltage.
What is relation between frequency and voltage of that frequency?
voltage and frequency both are different quantity.. don't mix it...
Frequency depends on voltage or current?
Frequency doesn't depend on either voltage or current.
Frequency to voltage converter IC's?
First of all that's an incomplete question, in fact it could hardly even be called a question. Nevertheless I will attempt to answer what I think the question might be. A Frequency to Voltage converter simply converts a frequency to a voltage as the name would imply. The voltage output will vary linearly with the frequency input (assuming it was designed properly). They can be useful in devices such as tachometers or speedometers. Here's one example of a such an IC: http://www.national.com/mpf/LM/LM2907.html
What is the effect of low frequency on the voltage?
The frequency would decrease the gain and increase the output voltage
What is the power frequency voltage?
It's unclear whether you are asking about frequency or voltage. The frequency and voltage are specified in the relevant national standards, regulations, and legislation. In North America, for example, the residential nominal voltage is 240/120 V at 60 Hz. In Europe, the residential nominal voltage and frequency is 230 V at 50 Hz. By 'nominal', we mean 'named'. National regulations allow these values to vary within specified limits.
What is the difference between 50 Hertz and 61 Hertz?
Frequency is determined by the supply voltage, not by the load. However, for reactive loads (inductors or capacitors), the reactance will vary according to the frequency applied.
What is the mains voltage and frequency used in the united kingdom?
The mains voltage is 230 volts, and the frequency is 50Hz.
What is the voltage and frequency used in US and why?
the voltage and frequency are 110v and 50(or)60hz because the devices which are invented in us are work at that voltage and it is efficient for that devices.
How can the frequency and voltage of an alternator be changed?
The frequency is changed by varying its speed, and the the voltage is changed by varying its field current.
Why do you not consider frequency in direct current?
Although DC current can vary in voltage and current over time, it does not reverse polarity, which in AC occurs some distinct number of times per second (hertz) which is the frequency.
What is the voltage a frequencies of mains electicty?
It depends on where you live, as most countries have their own standards. In the UK, for example, the nominal (named) mains voltage is 230 V, but it is allowed to vary between +10% and -6%. The nominal frequency of this voltage is 50 Hz, and this is allowed to vary between +/-1%. In North America, the standard nominal supply voltage is 120 V at 60 Hz.
