Ac relay and DC relay?
what is the meaning of ac relay and dc relay EDIT: a DC relay is simply a coil and core that pulls on an armature. An AC relay usually needs a shaded-pole core (couple of copper loops) to prevent the armature from vibrating at 60 cycles or so. The core, also, is laminated steel like a transformer; so is the armature to help contain the magnetic field. You should not substitute a DC rated relay for an AC , but the reverse should be ok, if voltage and current ratings are the same.
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 is the function of armature core in dc generator?
this is wer the armature conductors ar being mounted,therefor it helps the flexibility of armature conductors.
Another name for a laminated iron core inductor?
choke
What is the reason for using laminated core?
Insulation of laminated core is required to reduce the circulating current points due to touching the two plates. This results in more iron loss and heat produced
What is the main material in a motor armature?
Instead of a single piece of metal, the armature is made up of laminated thin metal plates. The thickness of the laminations is determined by the supply frequency. They are approximately 0.5mm thick. For the armature core, silicon steel laminates are used to reduce eddy currents and hysteresis losses.
Why armature core is laminated in dc machine?
to reduce the eddy current loss in the machine
The movement of which subatomic particle causes an electric motor to run?
Eectrons moving in the wire that is why it is called electricity. Electrons moving in a circle around the iron core called the armature produces a magnetic field. This produces a north and south pole. The poles of the armature are attracted to the opposite poles of the magnets, causing the armature to spin.

Why do you get a typical sound when the transformer is put into operation?
vibration of the transformer's laminated core in response to the AC magnetic field.
Why is the core laminated?
The iron core of Transformers is laminated to reduce eddy currents, which cause a loss of energy.
Why the core is laminated in TF?

What is armature core?
g55
How Core losses can be reduced?
by using the laminated core
Does the moon have a magnetic pole?
The Moon has a solid core, and therefore has no magnetic field or poles.

this is wer the armature conductors ar being mounted,therefor it helps the flexibility of armature conductors.
