Description
を制御するために界磁電流を生成する。システム100は更に、図2に関して更に記載するように制御システム全体200の一部(例えばコンピュータ)であって良いヒューマンマシンインターフェース125を含む。例示的実施形態では、図2に関して更に記載するように、より大きなネットワークの一部であって良いイーサネット(商標)130を介して制御システム200をシステム100に作動的に連結する。
ω=2Π*N/60、及び
機械的動力P(ワット)=T(N−m)*(2Π*N)/60 、
ただしP(HP)=P(ワット)/745.7である。従って、
P(HP)*745.7=2Π*N*T(N−m)/60 (1)
=1.732*ボルト*アンペア*力率(等価電力)
上記の方程式(1)を解く際に、必要な電流設定値が導出される。同様に、以下のようにLbf−ft単位の必要トルクも得ることができる。
T(lbf−ft)=P(HP)*745.7*60/(N*2Π*1.356)
T((lbf−ft)=P(HP)*5251/N(rpm)
技術的効果には起動プロファイルの短縮を達成し、且つ起動中の高温ガス通路へのタービン部品への露出を減少した起動トルクの生成が含まれる。
