Uyilo lokunciphisa ingxolo yemoto etshintshileyo, uyilo lokunciphisa ukungcangcazela, uyilo lolawulo lwe-torque ripple, akukho sensor yesikhundla, kunye noyilo lwesicwangciso solawulo ibe ziindawo zophando ze-SRM. Phakathi kwazo, uyilo lwesicwangciso solawulo olusekwe kwithiyori yolawulo lwangoku kukucinezela ingxolo, ukungcangcazela kunye nenkonzo ye-Torque ripple.
1. Ingxolo kunye nokungcangcazela kwe-SRM kucinezela ingxolo kunye nokungcangcazela
Injini yokungafuni ukutshitsha, eyona nto ingundoqo ethintela ukunyuswa kwe-SRM. Ngenxa yolwakhiwo oluphindwe kabini lwe-convex, indlela yokulawula ye-asymmetric half-bridge kunye ne-non-sinusoidal air-gap magnetic field, i-SRM inengxolo yendalo, i-vibration inkulu kunaleyo yee-asynchronous motors kunye ne-magnetic motors ezisisigxina, kwaye apho. Zininzi iinxalenye ze-high-frequency, isandi sibukhali kwaye sigqobhoza, kwaye amandla okungena omelele. Izimvo zophando zokunciphisa ingxolo kunye nokunciphisa ukungcangcazela zahlulwe ngokubanzi ngokweendlela ezininzi:
1) Uhlalutyo lwemodyuli, funda impembelelo yesakhelo, isitator kunye nemilo yerotor, ikhava yokuphela, njl.njl. kwimowudi yoku-odola nganye, hlalutya ubuninzi bendalo phantsi kwemowudi yoku-odola nganye, Phanda ukuba i-electromagnetic excitation frequency ikude kangakanani nobuninzi bendalo. imoto.
I-2) Nciphisa ingxolo kunye nokunyakaza ngokuguqula imilo ye-stator kunye ne-rotor, njengokutshintsha i-ji arc, imilo, ubukhulu bejoka, i-sloting ye-key position, i-oblique groove, i-punching, njl.
3) Zininzi iinoveli zezakhiwo zeemoto ezenziweyo, kodwa zonke zineengxaki. Mhlawumbi ukuvelisa kunzima, ixabiso liphezulu, okanye ilahleko inkulu. Ngaphandle kokukhetha, zonke ziimveliso zelabhoratri kunye nezinto ezizalelwe ithisisi.
2. Ulawulo lwe-torque pulsation ye-motor eguqukayo yokungafuni
ngokusisiseko iqala ngolawulo. Ulwalathiso oluqhelekileyo kukulawula i-torque ngokukhawuleza okanye ukuphucula i-torque ephakathi. Kukho ulawulo oluvaliweyo kunye nolawulo oluvulekileyo. Ulawulo lwe-loop oluvaliweyo lufuna impendulo ye-torque okanye nge-current, Izinto eziguquguqukayo ezifana ne-voltage yokubala i-torque ngokungathanga ngqo, kunye nolawulo oluvulekileyo lwe-loop ngokusisiseko lujongo lwetafile.
3. Uphando malunga nesivamvo sesikhundla semotor eguqukayo yokungafuni
Ulwalathiso olungenayo inzwa yesikhundla ngumvelisi omkhulu wamaphepha. Kwithiyori, kukho iindlela zokutofa kwe-harmonic, iindlela zokuqikelela i-inductance, njl.n Ngoba? Ndicinga ukuba kusengenxa yokungathembeki. Kwizicelo zamashishini, ulwazi lwendawo olungathembekanga lunokubangela iingozi kunye nelahleko, ezingenakunyamezeleka kumashishini kunye nabasebenzisi. Iindlela zangoku ze-SRM ezithembekileyo zokubona indawo ziquka i-low-resolution sensors positions ezimelwe ngokutshintshwa kweefoto zombane kunye nokutshintsha kweHolo, ezihlangabezana neemfuno zokutshintsha kweemoto kwiimeko eziqhelekileyo, kunye ne-high-precision position sensors emelwe yi-encoder photoelectric kunye nezisombululo. Ukuhlangabezana nesidingo solawulo oluchanekileyo.
Oku ngasentla ngowona mxholo uphambili wemoto yokungafuni ukutshintshelwa. Phakathi kwabo, isixazululi sohlobo lokwahlula sikulungele kakhulu ukusetyenziswa kwe-SRM, kunye nobukhulu obuncinci, ukuchaneka okuphezulu kunye nokuguquguquka okuhle kokusingqongileyo. Ndicinga ukuba lukhetho olungenakuthintelwa lwe-servo SRM kwixesha elizayo.
