It's the bit that spins in the middle, turned by the the drive belt.
The rotor contains coils of wire, which are connected via slip rings to the control circuitry.
Dc power applied to the rotor, turns it into an electromagnet. This will then induce an AC current in the stator windings, as the rotor turns within it.
The strength of the 'rotor' electromagnet, can be varied by the control circuitry, to maintain the voltage and control the current demand.
The AC outputs from the stator coils are rectifed (ususally three phase) back into DC, for use in the cars electrical system and battery charging.
What else can I help you with?
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 couple DC motor to alternator?
Shaft(rotor) of DC motor and Alternator(AC Generator) are alligned axially and radially to each other and connected.
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 brushless excitation system?
3 phase synchronous generator or motor require DC current in the rotor. Conventional way of supplying DC requires use of commutators, which requires timely maintenance. To overcome this Brush less Excitation systems is used. Brushless Escitation system consists of one pilot excitor - DC generator with rotating PM as the field and the armature as the stator. The armature of the pilot excitor is connected to the stator of main excitor which is a 3-phase synchronous generator (please do not get confused, this is not our alternator but the exciter for the alternator). The rotor of the main exciter is connected to a diode bridge to get DC. This is connected to the rotor of our alternator.
Why field windings of synchronous alternator are excited by dc?
The 'field'winding is in the rotor which rotates at the synchronous speed generating AC powerat the right frequency in the stator. That requires DC in the rotor. It is convenient because the DC is supplied to the rotor through slip rings, smooth polished rings which allow the carbon brushes to last a long time.
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.
What is the name of the rotating electromagnet in an alternator?
The rotating electromagnet in an alternator is called the rotor.
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.
What is the purpose of an alternator?
The purpose of an Alternator is to periodically recharge the battery while the engine is on.
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 is the purpose of the alternator?
Charge the battery.
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 drive end shield in an alternator?
The drive end shield in an alternator serves as a protective cover for the rotor and other internal components. It supports the bearing that allows the rotor to spin smoothly and maintains alignment within the alternator. Additionally, the drive end shield helps to contain any debris and prevents external contaminants from entering the alternator, ensuring optimal performance and longevity.
