1. UmGaqo oPhambili wokuSebenza weTekhnoloji yokuQhuba iFrequency eguquguqukayo

IEguquguqukayo Frequency Electric Motorisebenza kumgaqo wokuhlengahlengisa i-frequency kunye ne-voltage enikezelwa kwi-stator windings. Ngokuguqula igalelo le-AC frequency nge-drive ezinikeleyo (i-VFD), isantya esihambelanayo sokutshintsha kombane ojikelezayo, ukuguqula ngokuthe ngqo isantya se-rotor ngaphandle kweegiya zoomatshini. Lo mmiselo we-elektroniki uchanekileyo ususa i-valve yokuchitha amandla okanye i-dampers, ngakumbi kwimithwalo ye-centrifugal efana neefeni kunye neepompo. Xa idityaniswe ne-Variable Frequency Electric Motor, abaguquli banamhlanje basebenzisa itekhnoloji ye-PWM esekwe kwi-IGBT ukwenza iifomati zamaza ezikufutshane ne-sinusoidal, ukunciphisa ukuphazamiseka kwe-harmonic kunye nokuphucula umgca we-torque ngesantya esiphantsi.

Ngokungafaniyo neenjini zemveli zokungenisa ezisebenza ngesantya esisisigxina kufutshane nezantya zomgca (50/60 Hz), ukusebenza okuguquguqukayo okuguquguqukayo kuvumela ukuqala okuthambileyo, ukunciphisa i-inrush yangoku ukuya kuthi ga kwi-70% kunye nokwandisa ubomi boomatshini. Ulawulo oluphezulu lwealgorithms — V/f, ulawulo lwevekhtha, okanye ulawulo lwetorque ngokuthe ngqo — qinisekisa ukuba iVariable Frequency Electric Motor igcina itorque ezinzileyo naphantsi komthwalo ohlukeneyo ngesiquphe. Oku kubaluleke kakhulu kwizixhobo zokuphakamisa kunye nee-rolling Mills apho imithwalo yokothuka iyenzeka rhoqo.
