How the output characteristics of AC and DC generator vary from other?

How the output characteristics of AC and DC generators vary from each other?

AC generators have a varying waveform which is sinusoidal in nature, whereas a DC output is linear.

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.

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.

What is the price of a 2500 rpm generators?

The standard rotation of a generator engine is 1800 revolutions per minute. This standard speed is brought about by the number of poles that the generator portion of a generator has in its stator.

How much power does an electric generator put out, and for how long?

This can vary greatly depending on the generator itself, as they come in quite a range of capacities and sizes. They can output from 2 or 3,000 watts right up to as much as 15,000 or more. They can run for several hours but will need regular oil and fuel maintenance after extended periods.

What Costs do not vary with output?

fixed cost

What is alternator output in amps?

The alternator (or generator) of a vehicle is the unit that converts the mechanical energy from the drive-belt into electricity. Amperage (amps) are the output level of the alternator. Alternator part number, as well as output amps are specific to each vehicle.Another AnswerYour question is a little like asking, "How long is a length of string?"! The rated output current of an alternator depends on its rated output power rating and its rated terminal voltage. The rated output power can vary tremendously, according to the physical size of the machine.

Convert 480 volt 60 hz to 380 volt 50 hz generator for international service?

1) Changing Engine Speed to Vary Output FrequencyPresent-day generators consist of an engine directly connected to an alternator to produce electricity. One of the most common ways of changing the output frequency of a generator is to change the rotation speed of the engine.The two factors are related as per the following formula -Generator Frequency (f) = Number of revolutions per minute of the engine (N) * Number of magnetic poles (P) / 120Conversely, P = 120*f/NAs per the above formulae, a 2-pole generator producing an output frequency of 60 Hz has an engine speed of 3,600 rpm. To change the output frequency to 60 Hz for the same generator configuration, the engine speed needs to be reduced to 3,000 rpm. Similarly, for a 4-pole generator, an engine speed of 1,800 rpm produces output of 60 Hz. Reducing the engine speed to 1,500 rpm yields an output of 50 Hz.In the case of small or residential generators, you can alter the engine rpm settings by making a few changes on the control panel of your unit. Follow the steps given below to alter your generator frequency from 60 Hz to 50 Hz:(a) Run your generator engine and tune the frequency meter on your control panel to read 50 Hz.(b) Check the AC voltmeter or potentiometer as the case may be and read the voltage output of the generator. The output voltage decreases as you reduce the frequency and may be lower than the desired value.(c) Adjust the AC voltmeter or potentiometer on your control panel till you obtain the desired output voltage at 50 Hz.(d) By making similar modifications on the control panel, you can increase the frequency from 50 Hz to 60 Hz.(e) If the control panel does not display the frequency, you will need to first connect a device that will measure the frequency while the generator is in operation and then change the engine rpm.Generator controller units undertake real-time monitoring and control of your unit. Built-in protective functions automatically shut down your generator in the case of excess engine rpm or very low output frequency. For addtional information on the functionality of a generator please read the following article, How Generators Work.

How much would a Yamaha generator cost?

Prices vary for a Yamaha Generator depending on the size of the generator. The more wattage involved, the more you will need to pay. First you need to determine the size of generator you need then contact a local retailer.

Does a signal generator generate sound waves?

A signal generator produces electrical signals that can be converted into sound waves by speakers or other devices. The generated signal can vary in frequency, amplitude, and shape to create different types of sound waves.

What is floating output?

Floating output refers to a type of output that can vary within a range. This output is not fixed and can change based on the input or external conditions. It is commonly used in electronic circuits and systems where the output is not constrained to a specific value.

How much does a used generator cost>?

The prices will vary depending on what size generator you need. If you are looking for one for the whole house, probably starting at 300 or 400 easily.
