The Armature Of Dc Generator Is Laminated To

Unlike the stator this part is moveable and rotates in the magnetic field created by the stator.

The armature of dc generator is laminated to.

The armature consists of a shaft upon which a laminated cylinder called amature core is placed. The sum of the eddy currents in the laminated core is smaller than the current in the solid core. The armature of d c. The top image depicts a solid armature while the bottom image shows an armature made of five laminations.

B reduce hysteresis losses. The armature of d c. Reduce the eddy current loss. A 0 005 mm b 0 05 mm c 0 5 m d 5 m ans.

Generator is laminated to a reduce the bulk b provide the bulk c insulate the core d reduce eddy current loss ans d 4. With laminated armature eddy current losses are reduced to very less. The second important component of a dc generator is the rotor or armature core that is consisted of a fan armature commutator and a shaft. Therefore smaller the current hence lesser eddy current loss.

Increase dissipation of heat from the armature surface. Reduce hysterisis loss. The rotating part of the dc machine or a dc generator is called the armature. The armature of d c.

May 27 2017 by admin. Generator is laminated to a reduce copper losses. The resistance of armature winding depends on a length of conductor b cross sectional area of the conductor c number of. The armature of dc machine is made up of laminated sheets to.

Armature of dc generator. Generator is laminated to a reduce the bulk b provide the bulk c insulate the core d reduce eddy current loss. In a dc generator the armature s rotation is the process that generates a voltage in the rotor coils. D all of the above.

The armature core of dc generator is cylindrical in shape and keyed to the rotating shaft. 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. Mcq on dc generator 1. Note thinner the laminations greater is the resistance offered to induced e m f.
