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
What material is used to make a water wheel?
wood
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.
Which type of motor uses a commutator?
Commutator is a device in a motor through which supply is fed.
What material is used to make a mill bed?
Cast iron
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
Why commutator are not used in ac motors?
Because, the commutator segments are used for converting AC to DC.
Why carbon brushes are used in DC machines?
Carbon brushes used in DC machines because carbon is soft material and it does not generate spikes when contact with commutator
How do you make a commutator?
you ask mr ritter
Why brushes are made up of carbon?
carbon is the only material when friction with any material doesn't produce scratches on commutator and avoid to produce spark.
Why carbon brushes are most used in dc?
Carbon is used because it is soft and does not damage the commutator. This means that the brushes must be replaced at intervals, and the powdered carbon scraped out from between the segments of the commutator.
What is velour material?
Velour material is material used to make tracksuits etc.
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.
Is commutator used for both ac to dc and dc to ac conversion?
Yes
In an electromagnet what are the springy pieces of metal or carbon that make contact with the commutator's contacts?
Brushes
What material is used to make a bow for a violin?
The material is Horse Hair :)
