Umehluko omkhulu phakathi kwama-motor synchronous akhiqizwa yi I-LT SIMO Motorfuthi ezejwayelekileama-asynchronous motors TDMK Motorekusebenzeni ukuthi lapho i-synchronous motor isebenza, i-engeli phakathi kwe-armature voltage vector kanye nendawo ye-rotor pole kufanele ibe phakathi kwebanga elithile, ngaphandle kwalokho uhlelo luzolahlekelwa isinyathelo. Ngakho-ke, uma i-synchronous motor iguqulwa imvamisa futhi ilawulwa isivinini, le engeli kufanele ihlale ilawulwa ukuze ishintshe phakathi kwebanga elivumelekile. Lona umehluko omkhulu phakathi kokuguqulwa kwefrikhwensi ye-synchronous motor kanye nokuguqulwa kwe-asynchronous motor frequency. Okulandelayo kuzokwethula kafushane ubunzima okuhlangatshezwene nabo kumotor synchronous fukulawulwa kwesivinini sokuguqulwa kwe-requencyinqubo kanye nezixazululo ezihambisanayo zedivayisi yokuguqula imvamisa ye-maxf:
I-synchronous motor yokuqala nenqubo yokuvusa amadlingozi
Ngokuvamile kunezindlela ezimbili zokuqala i-asynchronous motor: eyodwa iwukujabulisa kuqala futhi uqale ngokuvumelanisa; enye iwukuqala ngokulinganayo bese ijabulisa nge-polarity efanayo. Ukuze kuqalwe ukuguqulwa kwefrikhwensi ye-synchronous motor, i-excitation iqala ukusetshenziswa bese kwamukelwa ukuqala okuhambisanayo, kodwa ukwahlulela okungalungile kwendawo yerotha kuvame ukuholela ekuhlulekeni kokuqala kwemoto. Ngokulawulwa kwesivinini sokuguqulwa kwefrikhwensi ye-synchronous motor, kulula ukwamukela ukuqala kwe-asynchronous kanye nokuya phambili kwe-polarity excitation. Ngakho-ke, idivayisi yokuguqula imvamisa ye-maxf yenza ukuthamba kwe-asynchronous iqala ku-synchronous motor ukuze kuzuzwe i-torque elinganiselwe yokuqala, futhi iqala injini yokuvumelanisa iye cishe ku-8hz ukuze kuthuthukiswe i-polarity eya phambili. Usayizi othize wenjabulo kanye nemvamisa yenjabulo ingalungiswa futhi inqunywe ngokuya ngezikhathi zohlelo lokusebenza ezihlukene. Kuleli qophelo, ngemva kokuba i-engeli phakathi kwe-motor rotor magnetic field kanye ne-stator magnetic field inenani elincane le-oscillation emanzi, isigxobo se-motor rotor magnetic sikhangwa ngokuthembekile yi-stator magnetic pole, kanye ne-synchronous motor ingena esimweni sokusebenza esivumelanayo. I-inverter kancane kancane isheshisa imvamisa enikeziwe ngokuya ngokusheshisa okusethiwe. Ngalesi sikhathi, i-engeli phakathi kwe-synchronous motor armature voltage vector kanye ne-rotor magnetic pole isikhundla kancane kancane ikhula ibe yinani elithile elingaguquki, futhi isigxobo se-motor rotor magnetic kancane kancane siphuthunyiswa ngesivinini esifiselekayo ngaphansi kokukhangwa kwe-stator magnetic field, futhi inqubo yokuqalisa i-motor synchronous iyaqedwa.
