The Armature Of Dc Generator Is Laminated To

The armature of d c.

The armature of dc generator is laminated to.

Are 270 v and 265 v their bus bar voltage will be. Therefore smaller the current hence lesser eddy current loss. Armature of dc generator. The rotating part of the dc machine or a dc generator is called the armature.

Generator is laminated to a reduce the bulk b provide the bulk c insulate the core d reduce eddy current loss ans d 4. That is why armature of dc machines either motor or generator is laminated. Shunt generators each with armature resistance of 0 02 ohm and field resistance of 50 ohm run in parallel and supply a total current of 1000 amperes to the load circuit. The individual iron pieces that make up the armature are referred to as laminations.

The resistance of armature winding depends on a length of conductor b cross sectional area of the conductor c number of. A 0 005 mm b 0 05 mm c 0 5 m d 5 m ans. 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. This is why armature cores are made up of many thin pieces of iron rather than a large solid piece.

The armature core of dc generator is cylindrical in shape and keyed to the rotating shaft. Note thinner the laminations greater is the resistance offered to induced e m f.
