Ukuguqulwa kwamaxesha kunye nokusebenza kokulawulwa kwesantya semoto ngokuthe ngcembe kube luphawu lwamaxesha. Ukulawulwa kwesantya semoto ehambelanayo kukuguqulwa kwamaza kunye nolawulo lwesantya soomatshini bokulayisha i-torque yesikwere esifana nefeni kunye nempompo eqhutywa kukuguqulwa kwamaza kunye nokulawulwa kwesantya semoto ye-AC kwinkqubo yokuvelisa. Ulawulo lwesantya soguqulo loguqulo lunokufumana eyona siphumo silungileyo senkqubo kunye nogcino lwamandla kunye nesiphumo sokunciphisa ukusetyenziswa.

amandla okugcina amandla

Izixhobo zoomatshini eziqhutywa yi-brushless excitation synchronous motor yemveli, enje ngeefeni, iimpompo, kunye neecompressors, zisebenza phantsi kombane ophindaphindwayo kwaye umbane uphuma rhoqo. Xa inkqubo ilungisa ukuhamba kwayo kunye noxinzelelo, iya kubangela ukuchithwa kwamandla okunzulu. Ngenxa yokuba umthwalo uguquka, izinga lokuhamba lilingana nesantya, kwaye amandla afunekayo alingana ne-cube yesantya. Ngoko ke, ukuba izinga lokuhamba elifunekayo liyi-80% yezinga lokuhamba okulinganiselweyo, kule meko yokwenene, ukusetyenziswa kokulawulwa kwesantya sokuguqulwa kwamaxesha anamhlanje kunokugcina ngaphezu kwe-45% yamandla ombane kunendlela yokulawula yendabuko.

Ulawulo lwenkqubo yokusebenza yokuguqulwa rhoqo

Umsebenzi wokulawula isantya sokuguqulwa kwesantya yinkqubo yokulawula yodwa. Inkqubo yokusebenza yokulawulwa kwesantya sokuguqulwa kwesantya iyafana nesantya sokuguqulwa kwesantya solawulo lwenkqubo yokuqala ethambileyo, kodwa kukho umahluko. I-cranking drive motor iyiqhubela ukujikeleza. Xa isantya sokujikeleza se-synchronous motor sifikelela kwi-1% yesantya esilinganiselweyo, i-synchronous motor iya kuyalela inkqubo yolawulo ngokwenkqubo eyilelweyo emva kokuba ulawulo lokuvuselela luvulwe, kwaye igumbi lolawulo ngokubanzi liya kukhupha “imvume yokutshintsha. ” “, oko kukuthi, vala isiqalisi esithambileyo sokutshintsha kombane ophezulu obonisa ukusebenza kolawulo lwesantya soguqulo. Kwangaxeshanye, ngokomyalelo wesignali, igumbi lolawulo jikelele ngokukhawuleza livala iswitshi ephezulu yevoltage yesekethe yolawulo oluphambili lwenkqubo yolawulo oluthambileyo lwe-synchronous motor frequency conversion speed regulation operation, ukuze i-synchronous motor ibe ngaphakathi. imo yokusebenza yokuqalisa ethambileyo yolawulo lolawulo lwesantya sokuguqulwa kwesantya.

Ngexesha lenkqubo yokulawula isiqalo esithambileyo soguqulo lwamaza kunye nokumodareyitha rhoqo kwi-synchronous motor, i-polarity ye-rotor magnetic pole ye-synchronous motor ihlala ingatshintshi, kwaye ukujikeleza kuyakhawuleziswa kunye nokuphindaphinda kwesantya sokuguqulwa kwesantya, kunye nombane. kwaye i-frequency inyuka ngokuthe ngcembe ukwenza i-synchronous motor ibaleke ngesantya esilinganiselweyo. Ulawulo lwesantya soguqulo rhoqo oluthambileyo lokuqalisa.

Ngexesha lokusebenza kwe-synchronous motor kunye nokulawulwa kwesantya esiguqukayo, ngokotshintsho loqobo lomthwalo, inkqubo yokulawula isantya sokuguqula isantya kunye nenkqubo yolawulo lweshishini elincinci lekhompyuter yombane iqonda ulawulo oluzinzileyo noluchanekileyo lolawulo lokusebenza lwe-vector. .

Ngaphambi kokumiswa kwemoto ehambelanayo kwisantya sokuguqulwa kwesantya sokuguqulwa kwesantya, isixhobo sokusebenza sokuguqula isantya kufuneka sinciphise ngokuzenzekelayo imveliso yangoku ukuya ku-zero, kwaye sithintele zonke ii-trigger zesixhobo sokulawula isantya sokuguqula isantya ngaphambi kokuba sinikeze "imvume yokuyeka" ukubonisa uphawu. Ngokomyalelo wesignali ebonisiweyo, umlawuli oyintloko unqumla ngokukhawuleza ukunikezelwa kwamandla okutshintsha kwe-high-voltage kwisiphaluka esiphambili solawulo lwesixhobo sokulawula isantya sokuguqulwa kwesantya, kwaye iphelisa inkqubo yokulawula isantya sokuguqulwa kwesantya.
