How does ac electric motor convert in to an alternator?
a motor is a generator and a generator is a motor, if you are applying a voltage to turn the rotor its a motor and if you are turning the rotor and taking the voltage off the terminals its a generator or alternator.
How do you step down frequency and voltage from an AC generator?
You step down voltage from an AC generator with a transformer.You step down frequency from an AC generator with a motor/generator set, or with an inverter. This is not a common thing to do.
What is excitation and why is it needed for start up in an AC generator?
An alternator is just another name for a synchronous generator. Excitation is needed to create a magnetic field in the rotor. When to rotor is spun with excitation the magnetic field will cut through the stator field and produce an AC voltage in the stator field. In terms of an alternator with built in rectifier the stators AC voltage in the rectified to DC. The strength of excitation will determine the alternators output voltage. The AVR Automatic Voltage Regulator built into almost every alternator controls field current to maintain a constant output voltage.
Can measure Automatic Voltage Regulator voltage of a generator by dc meter?
No, you cannot accurately measure the output voltage of an Automatic Voltage Regulator (AVR) using a DC meter, as the AVR typically regulates AC voltage for the generator. A DC meter is designed for measuring direct current voltage, while the voltage output from a generator is usually alternating current (AC). To measure the AC voltage effectively, you would need an AC voltmeter or a multimeter set to the AC voltage setting.
What circuitry converts an ac voltage into dc voltage?
either a rectifier or a motor generator

Which statement describes an AC generator?
AC generator is a rotating machine with a rotor and stator winding, driven by another prime mover, which generates alternating current at a specified voltage.

Does a generator produce ac or DC voltage?
NO, generator always generating AC current,when commutator is used,at that time AC is converted in DC.and due to this generator is called dc generator.

Whar are stators and rotors?
It is the active parts of an alternator. The rotor is the inside rotating part that is connected via slip ring to a DC voltage normally supplied by the exciter, that can be a DC generator on the same shaft as the rotor or it can be a diode bridge that is converting AC from the stator to DC and is regulated by the AVR(Automatic Voltage Regulator). The rotor serves is the rotating magnetic field that is induced in the stator where the output AC mains is generated
The amount of voltage output of the AC generator is related to?
field strength
What type of voltage is the output at the bat terminal of the ac generator?
dc
What is needed to generate AC electricity?
An AC generator (Alternator). A rotor is turned into a magnet by what is known as 'excitation' current. The rotor then induces AC current in the stator windings as it is rotated within it. This is AC, due to the fact that the rotor has a north and south pole, which alternately induces current in the stator windings. The exitation current is provided to the rotor via slip rings. Controlling this excitation current will also control the output power by suitable control circuitry. This is the same principle, whether it is a small domestic generator, a power station, a wind turbine, or a car alternator.
Does a ac generator have a brush?
AC generators (alternators) usually have a dc supply to the rotor coils, supplied through slip-rings with carbon brushes. Because the slip-rings can be made very smooth the life of the brushes is greatly extended when compared with brushes on the commutator of a dc motor or an ac commutator motor. Cars generate electrical power with a three-phase AC alternator, connected directly to the battery through rectifier diodes. The alternator voltage is controlled by the voltage regulator, which works by controlling the dc supply to the rotor.
