A generator's frequency is dictated by the power system frequency, and the number of poles in the generator. For 60 Hz power and a generator designed with two poles, the generator must turn at 3600RMPs (60 Hz * 60 seconds / minute).
The magnetic flux is what induces the current in on the output winding.
Spinning a synchronous generator faster or slower is not done to control the magnetic flux. The field winding voltage is varied to control this, and in turn control the output of the generator.

What is a exciter generator?
its creates the magnetic field trough the electricity,which we called exciter for it.we send some electric shocks to the field coils,then it will magnetized the stater of the generator. When Diesel or petrol engine rotates the rotter of the generator, EXCITED stater act as a magnet. Depend on alternator`s design,rotter or stater one always EXITED to be a magnet. When engine turns the Alternator against the magnetic field,electricity is produced.
What is difference between frequency and slip frequency?
Both 3-phase induction motors and single-phase induction motors have rotating magnetic fields assuming that the single-phase motor has one of the usual starting mechanisms built-in. The synchronous speed is given by RPM = 120 X f / p where f is the frequency and p is the number of poles. The conductors in the rotor pass through the magnetic field of the stator at the slip speed. As a result an alternating current is generated in the rotor. The frequency of that current is the rotor frequency or slip frequency given by slip frequency = slip speed X p / 120. At full load, the slip speed of a standard, 3-phase motor is about 1% to 2.5% of synchronous speed. A motor with 6% slip would be classified as a high-slip motor. The slip of a standard single-phase motor could be 6%.
A generator 1mw rated means what does it produce 1mw per hour or day or what?
A Generator 1MW means, this is the capacity of that generator, It can deliver max of 1MW at any given time. Nothing concern with 1Hr or 1 Day.
What happens if an ac supply is given to dc generator?

Generator excitation voltage?
the voltage which is given for creating magnetic field in a generator is known as excitation voltage.
What is the cyclotron frequency formula used to calculate the frequency of a charged particle moving in a magnetic field?
The cyclotron frequency formula is given by f qB / (2m), where f is the frequency, q is the charge of the particle, B is the magnetic field strength, and m is the mass of the particle.

What is the password for the Imvu credit generator?
The password for the IMVU credit generator is given once the generator is successfully downloaded.
Does an electric generator motion produces magnetism or power or electricity?
An electric generator produces electrical energy. It converts mechanical energy to electrical energy by interacting with a magnetic field. The amount of electrical energy converted to useful work in a given time interval is the power output. If the generator is not connected to any load, then no work is done and there is no power.
What does Incoming and running generators are in same phase while paralleling two generators mean?
When two generators are to be run in parallel, one generator is first started and some load is given. Then second generator is brought in parallel with the running generator (subject few conditions, like voltage, frequency, phase angle). First generator which is running is known as running generator, the second generator which gets connected is known as incoming generator

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.
