Mai suna da kuma ake da suka shafi na makina na DC?

Me ke da shi ne zaɓuɓɓuka a wata DC?

Bayanin Zaɓuɓɓukan Wata DC

A wata DC, zaɓuɓɓukan suna nufin karamin gaba mai yawa ba suka haɗa da fadada ta hanyar tushen ruwa, wanda ya ƙara tsari.

Zaɓuɓɓukan Copper

Wadannan suka faru a cikin windings saboda resistance, kuma ana ƙirƙira zuwa armature loss, field winding loss, da brush contact resistance loss.

Armature copper loss = Ia2Ra

Idan, Ia shine armature current da Ra shine armature resistance.

Wadannan zaɓuɓɓukan suke zama 30% daga cikin zabubbukan daɗinsa.

Zaɓuɓɓukan Core

Wadannan suke ƙunshi hysteresis loss, saboda haske kan fanin magnetization a cikin armature, da eddy current loss, wanda ya faru saboda emf na inganta a cikin core na iron.

Zaɓuɓɓukan Mechanical

Zaɓuɓɓukan da suka faru saboda mechanical friction na machine suna nufin zaɓuɓɓukan mechanical. Wadannan zaɓuɓɓukan suka faru saboda friction a cikin abubuwan da suke yi lalle a cikin machine kamar bearing, brushes, da kuma windage losses suka faru saboda harshe a cikin coil na machine. Wadannan zaɓuɓɓukan suna zama mafi yawan 15% daga cikin zabubbukan daɗinsa.

Hysteresis Loss a wata DC

Wani ƙarin nau'o'in zaɓuɓɓukan core wanda ya faru saboda haske kan fanin magnetization a cikin core na armature, wanda ya ƙara karamin energy.
