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.
The commutator of a universal motor connects each armature coil to?
to a brush
How do you change an ac motor to a DC motor?
Ac motor have slip ring, to remove the slip ring,connected to the commutator its a dc motor.
What does the split ring commutator do in a motor?
It generates a alternating current to keep the motor rotating in the same direction.
The part of the armature that the brushes ride on is called the?
Motor brushes ride one the commutator.
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 is the basic difference between carbon brush of AC slip ring motor and carbon brush of Direct current commutator motor?
The only difference between slip rings and commutator is that commutator can change the frequency where as the slip rings can not do it.
What part of the motor is current supplied to on a ac motor?
commutator, armature
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
What is the basic working principle of fan?
CAPACITOR STRAT AND capacitor run of a induction motor
If a DC electric motor turns backwards is it the wiring to the commutator or the wrong commutator installed?
I had a 28 volt motor armature and field rewired,it now turns the wrong way,the technician says it has the wrong commutator installed,,and cannot find a new one.
What motor does not have a commutator?
AC, its all done with coils- or electromagnets.
What is the purpose of a commutator in a electric motor?
A commutator applies power to the best location on the rotor, and in a generator, picks off power similarly.
Basic principle of electric train?
The basic principle of the electric train is quite simple. An electric motor in the locomotive or above each car is charged with electricity propelling the train forward or backward.
The commutator of a universal motor connects each armature coil to?
to a brush
