鐵芯磁通量 的英文怎麼說
中文拼音 [tiěxīncítōngliáng]
鐵芯磁通量
英文
core-flux-
When the secondary circuit is closed, both primary and secondary currents set up a flux in the core.
當次級電路接通時，初級電流和次級電流都在鐵芯內建立了一個磁通量。When the secondary circuit is open, the core flux is produced by the primary current only.
當次級電路開路時，鐵芯磁通量僅僅由初級電流產生。In the actual cases, there are many motors often operate on low load with low power factor and low efficiency, also there are many motors operate on the magnetic flux saturate region with high energy consumption, a large mount of energy used by ac motors is wasted due to all of those factors
在實際運行中，許多電動機經常處在低效率、低功率因數的欠載運行狀態下，還有許多電機則是鐵芯磁通常進入飽和區的高能耗電機，這些因素均可導致大量電能的浪費。Core losses are caused by an alternating magnetic field in the core material, thie losses are a function of the operating frequency and the total magnetic flux swing, the total core losses are made up of three main components, hysteresis eddy current and residuallosses, these losses vary considerably from one magnetic material to a - nother, applications such as higher power and hither frequency switching regulators and rf designs require careful core selection to yield the highestinductor perfor - mance by keeping the core losses to a minimum
鐵損是由於在鐵芯中的變更磁場院所造成，這個損失與操作頻率及總流動的磁通量有關，總鐵損由三個成份組成，磁滯損，過流損及殘留損，這些損失因磁性材料不同而異，在如高功率切換調整器和rf的設計需要小心選擇鐵芯種類以降低鐵損使電感的表現最佳。分享友人
