What else can I help you with?
In an electromagnet what are the springy pieces of metal or carbon that make contact with the commutator's contacts?
The springy pieces of metal or carbon that make contact with the commutator's contacts in an electromagnet are known as brushes. Brushes are responsible for delivering electrical current to the commutator, allowing the electromagnet to function as intended.
What is use of commutator?
The commutator is used to convert the AC to DC
What is the use of Commutator?
The commutator is used to convert the AC to DC
What are reasons for arcing at the commutator?
A shorted coil or shorted coils in the rotor will cause arcing at the commutator. It should also be noted that if the brushes are damaged badly enough where they make contact with the commutator, this can cause arcing. Oh, and let's not forget that a stuck brush or brush spring will prevent a brush from making proper contact with the commutator. Arcing can result from that, too.
What are the springy pieces of metal or carbon that make contact with the commutator's contacts?
It's a small block of graphite. The graphite acts as both the electrical contact to the commutator and as a lubricant to reduce drag and wear.
Explain the necessity and principles of commutator in Dc generator?
what is necessity of commutator in DC generator
What are the two reasons for arcing at the commutator?
A shorted coil or shorted coils in the rotor will cause arcing at the commutator. It should also be noted that if the brushes are damaged badly enough where they make contact with the commutator, this can cause arcing. Oh, and let's not forget that a stuck brush or brush spring will prevent a brush from making proper contact with the commutator. Arcing can result from that, too.
Why commutator are not used in ac motors?
Because, the commutator segments are used for converting AC to DC.
What is the definition of commutator?
A commutator is an electrical switch that periodically reverses the current direction in an electric motor or electrical generator. A commutator is a common feature of direct current rotating machines.
How does the commutator reverse the current in a motor?
Commutator is a split ring which reverses the current .when the commutator turns around due to magnetic force and because of it even the current gets reversed
Which type of motor uses a commutator?
Commutator is a device in a motor through which supply is fed.
Is a commutator the rotating element of a motor?
The commutator is part of the armature on a DC motor and this assembly is the rotating element of a motor.
