The rotor is a electro magnet with a North and South pole at ether end the ends have fingers that wrap around the centre coil of wire alternating North and South magnetic polarity fields. The more current supplied to the rotor the stronger the magnetic field, the more current produced in the stator and the higher the output amperage supplied to the electrical system

What is rotor in ac alternator?
A Rotor is a mechanism in the alternator that is driven by the pulley belt from the engine.which creates a magnetic field which causes voltage.Answer.The rotor does not 'create' a magnetic field. The emf induced in the stator winding is due to the residual magnetic flux of the rotor which cuts the stator windings as the rotor rotates.
If an alternator is being driven by a gasoline engine how is the speed of the alternator's rotor controlled?
by an amortisseur coil
What does a stator do on motorcycles?
If we are talking about a dynamo or an alternator, a stator has a rotor inside it. When the rotor turns, electricity is generated.
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.
What are the main parts inside the alternator?
*stator *rotor *regulater *rectifier
What are the four main parts of a car's alternator?
The four main parts of a car's alternator are the regulator, rotor, stator, and diode bridge.
What three things are required to produce EMF in an alternator?
armature, stator, rotor
Is there an alternator on a Yamaha Warrior 350?
Not in the same way as there is an external alternator in a car but there is a rotor and a stator inside the engine that serves a similar purpose.
How do you couple DC motor to alternator?
Shaft(rotor) of DC motor and Alternator(AC Generator) are alligned axially and radially to each other and connected.
What is the function of the brush holder in the alternator?
The brush holder in an alternator keeps the brushes held to slip rings with spring pressure (or commutators in generators or some motors) which provide electrical contact to electromagnets in the spinning rotor. By varying the electrical current through the brushes to the rotor magnets, you can adjust the power output of the alternator as needed.
Where does the voltage that is necessary for field excitation on the rotor originates from?
The excitation current is provided by a small self-excited pilot generator, attached to the same shaft as the alternator's rotor.
What is alternator?
It is a device that converts mechanical energy to electrical energy on a car. It works by:the alternator creates an electric field by spinning a magnetic rotor with direct current inside stator windings. an ac voltage is developed and rectified dc. this voltage is compared to the battery voltage and determines the current through the rotor. if the battery voltage is lower than the alternator voltage, more current through the rotor increases the magnetic field and creates a larger alternator voltage. if the battery voltage is higher, less current through the rotor decreases the alternator voltage.
