What is meant by shaft and commutator in the armature?
ShaunMarshgp7659
The armature is the moving part of a motor or generator.
Tthe shaft is the central rod on which the armature rotates.
The commutator is the part that transfers the power too or from the moving windings in the armature to the static part of the motor or generator (either too or from the electricity supply).

The commutator of a universal motor connects each armature coil to?
to a brush
Basic principle of commutator motor meter?
It is based dynamometer principle with ironless motor with a wound armature having a commutator. The two coils are connected in series with supply and armature coil is connected in parallel to it.
The part of the armature that the brushes ride on is called the?
Motor brushes ride one the commutator.
Which one of the following parts of a universal motor does not move a armature b the field coil c the shaft d the commutator?
B. The field coil (source page 36 of study unit 3, Appliance repair)
What does a armature or rotor do?
The Armature(or rotor) is a electromagnet inside a motor and alters the magnetic field inside the motor when it rotates. In DC motors it is connected to a Commutator. In AC induction motors the armature isn't connected to a power source.
What are the parts of simple loop generator?
yoke,magnetic poles,armature,field winding,shaft,armature winding,commutator
What does the brushes and commentator in a D C motor do?
i have never heard of a commentator in a motor, think you may be mistaking that word. inside an electric motor you have a stator and windings, as polarity changes it spins the stator and the brushes transfer the charge to the device being used.. I think they meant commutator. If you break an electric motor down to 2 parts, you have a commutator and an armature. the armature being the shaft that basically floats on bearings, and the commutator being the hull where the stator is. (and there is such thing as a brushless electric motor.) the stator does not spin. that is the term used for the magnets that pull the electric field supplied by the brushes. To make even more simple, imagine a shaft floating on bearings with 2 magnets on it, one positive and one negative ( the armature) and this shaft is inside of a ring of electricity the is flowing in one direction, its going to pull the negative and push the positive (the commutator) and cause the armature to spin.
What is the main part of ac motor?
shaft, windings, ball bearings, armature, stator, commutator, brushes, terminals, case.
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.
Define the brush on a dc motor?
The brush is actually a piece of carbon placed on the rotating commutator of the motor. it will be in pairs. Since the armature shaft rotates but gets the continuity through these brushes.
The commutator of a universal motor connects each armature coil to?
to a brush
What part of the motor is current supplied to on a ac motor?
commutator, armature
Basic principle of commutator motor meter?
It is based dynamometer principle with ironless motor with a wound armature having a commutator. The two coils are connected in series with supply and armature coil is connected in parallel to it.
What part of a DC motor on the armature is responsible for connecting brushes to a coil?
commutator
What part of an electric motor repels the poles of the permanent magnets?
commutator
What does the commutator in an electrical motor do?
If there is a commutator, it means you are dealing with a DC motor.The commutator acts like a switch to supply voltage to a revolving armature from the stationary brush assembly.A commutator has commutator bars, each seperated by mica insulation. Each coil of the rotating armature is connected to two bars that are in directly opposite positions across each diameter of the armature.The total number of commutator bars depends on the design of the windings on the armature: either "lap" or "wave" windings can be used on a DC motor or generator which is provided with a commutator.For more information see the answer to the Related question and also the Related link shown below.
Name two reasons for arcing at the commutator?
1) When the armature is open. 2) When the Field is open. 3) Commutator segments are internally short.
