The Armature Of Dc Motor Is Laminated To Reduce

Armature reaction refers to a phenomenon in dc machines where the magnetic field of the poles is distorted by the magnetic field produced by the armature current.

The armature of dc motor is laminated to reduce.

How to reduce armature reaction in dc machine. Dissipate more heat view answer. 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. Reduce armature copper loss.

Similarly armature core is laminated to reduce eddy current losses. Reduce pulsation loss. Reduce the eddy current loss. To reduce the eddy current loss in the machine.

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. Direct current machine or dc machine objective questions and answers. Increase dissipation of heat from the armature surface. By using thin laminations we increase resistance of eddy current path thereby reducing the eddy currents and eddy current losses.

Reduce hysterisis loss. The armature of dc machine is made up of laminated sheets to. The armature of d c. Reduce iron weight.

Pole shoe of a dc machine is. Therefore smaller the current hence lesser eddy current loss. One of the role of the armature in the dc motor is to carry the current that is crossing the field. Generator is laminated to a reduce the bulk b provide the bulk c insulate the core d reduce eddy current loss.

0 0 1. That is why armature of dc machines either motor or generator is laminated. Why armature core is laminated in. 1 the armature reaction causes the distortion in main field flux.

With laminated armature eddy current losses are reduced to very less. Reduce pulsation loss your comments. Reduce armature reaction.
