What is armature current?
Armature current is the current flowing in a motor's armature. The "armature" is another name for the coil (or coils) of wire which are on the motor's "rotor", which is the part that rotates inside its stator. (The "stator" is the fixed, non-rotating part of the motor.)
Would the motor turn if only the armature were excited?
A motor will turn when only the armature is excited, if there is enough residual magnetism in the field.
Why dc series motor cannot be start without any load?
If a DC series motor is started without load, the armature winding (winding that doesn't spin) current will be at a minimum, resulting in the motor going to maximum speed / runaway, which can cause things to fly apart. As Armature current increases, the speed of the motor will decrease. The armature current will be forced to increase / speed of the motor will be forced to decrease as more and more load is applied.
What is a coil of wire in a motor called?
armature
What is electromagnet in an electric motor called?
armature..!
Does a motor spin faster if the armature is winded less?
no. it doesnt...

Can electricity energy turn into another energy?
By using a motor electricity makes a turning armature spin. That is changing electrical energy into kinetic energy
What is armature in DC motor?
The armature has the stationary (not physically moving) magnetic field, which attracts the magnetic field in the rotor. Since DC does not alternate, a split ring is used to alternate the current (and resulting magnetic field), so that the rotor will spin.
What is the electomagnet in a motor called?
Armature

What is the function of armature winding of a motor?
Armature is a rotating part of the machine, the coil which wound in the core of that rotating part.
What part of the motor is current supplied to on a ac motor?
commutator, armature
Correct definition of the term armature?
The rotating coil of a dynamo or electric motor is called armature.
What is armature amps?
Armature amps refer to the current flowing through the armature winding of an electric motor or generator. It is used to power the electromagnetic coils that generate the magnetic field needed for the motor or generator to operate efficiently. Monitoring armature amps is crucial for maintaining the proper functioning and performance of the motor or generator.
In DC motor is the armature plus brushes resistance substantially the same for every rotational position of the armature why?
In a DC motor, the armature resistance and brush contact resistance remain relatively constant across different rotational positions because these components are primarily resistive and do not change with position. The brushes continuously maintain contact with the commutator segments as the armature rotates, ensuring a consistent electrical path. While the inductance and back EMF may vary with position, the resistance itself is a fixed characteristic determined by the materials and design of the armature and brushes. Therefore, the overall resistance remains substantially the same throughout the armature's rotation.
