What else can I help you with?
In the generation of electricity commutator would be used on an alternating current generator and slip rings would be used on a direct current generator?
No. Just the opposite. An AC alternator uses slip rings, a DC generator uses a commutator. Most modern auto alternators are in fact AC alternators that rectify the AC output to DC using a diode bridge.
How ac works in aeroplanes?
AC power is made by alternators driven off the the aircraft engines CSD . That is a form of transmission that operates alternators, generators and pumps.
What is voltage in rotor of 11 KV AC generator?
Star (or 'wye') connected alternators have a phase voltage of 6.35 kV, and a line voltage of 11 kV. Incidentally, it's 'kV', not 'KV'.
How many belts are used for alternators in AC coaches?
8
What is the difference between alternators and dynamos?
Alternators produce AC, which is rectified by diodes if DC is needed. Dynamos produce DC by using a commutator.
What is induction motor?
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
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.
Can you generate direct current?
Direct current can be generated by a generator. Generators are not as efficient as alternators ( that generated AC power ). Vehicles use direct current but come equipped with alternators. The AC power is rectified ( changed to DC ) for use.
What charges an alternator?
Alternators convert rotating mechanical energy into electrical energy. Alternators produce electrical energy by induction of the coil wires by the spinning electromagnet rotor. The back voltage and eddy currents produce a magnetic field that opposes the rotation of the rotor, conserving total energy.
What kind of rotor is most suitable for turbo alternators which are designed to run at high speed?
Smooth cylindrical type
What are the two different forces acts in opposite direction on the rotor of single phase induction motor?
An induction motor has an AC power source applied to the stator and an AC source applied to the rotor, through slip rings. The rotor spins a sub synchronous speed, which creates the phase shift between rotor AC and stator AC. This phase shift (known as slip) is what creates the torque.
What do you understand about the stator of an AC motor?
AC motor has two main winding components - stator and a rotor. Stator winding is stationary where as rotor winding is on rotating part.
