The Armature Of A Dc Motor Is Laminated

Generator is laminated to a reduce the bulk b provide the bulk c insulate the core d reduce eddy current loss. The armature winding of dc motor is attached to the rotor or the rotating part of the machine and as a result is subjected to altering magnetic field in the path of its rotation which directly results in magnetic losses. For this reason the rotor is made of armature core that s made with several low hysteresis silicon steel lamination to reduce the magnetic losses like hysteresis and.

So is the armature to help contain the magnetic field.

The armature of a dc motor is laminated.

You should not substitute a dc rated relay for an ac but the reverse should be ok. The armature of d c. Because of this manufacturers strive to make armature core laminations as thin as practical from a manufacturing and cost standpoint with modern dc motors typically using laminations that are 0 1 to 0 5 mm thick. The armature of dc machine is made up of laminated sheets to.

Question is the armature of a dc machine is laminated options are a to reduce the hysteresis loss b to reduce eddy current loss c to reduce the mass d to reduce the inductance e leave your comments or download question paper. A plain solid iron armature would waste a lot of energy in at least two ways. Reduce hysterisis loss. Adding silicon to steel increases its electrical resistance improves the ability of magnetic fields to penetrate it and reduces the steel s hysteresis loss.

The commutator segments are connected to the armature conductor by means of. The magnetic field that is produced by. The core also is laminated steel like a transformer. That is why armature of dc machines either motor or generator is laminated.

Silicon steel also known as electrical steel is steel with silicon added to it. Therefore smaller the current hence lesser eddy current loss. Motor laminations are created by using electrical steel laminations. Dc motor or direct current motor multiple choice questions and answers.

Motor armatures have to be made of thin laminations of iron to work efficiently. By reversing the connections of either the armature or the field winding connection with the supply.
