Kune marudzi maviri e AC induction motors anowanzo shandiswa muindasitiri: single-phase motors uye polyphase mota. Pakati pemapoka epolyphase, matatu-phase induction motors ndiwo anonyanya kushandiswa.Muchikamu chimwe chete chemotokari, mapoka mashanu akasiyana-siyana anowanzo shandiswa, ayo ari kupatsanurwa-chikamu, capacitor-kutanga (CS inosiyana-siyana yemotokari yepakati), shaded pole (shaded pole)), zvachose split capacitor ( PSC, zvachose split capacitor) uye capacitor kutanga-capacitor run (capacitor kutanga-capacitor run, CSCR inosiyana yePSC mota).
Kazhinji, kupatsanurwa-chikamu, capacitor-kutanga, uye capacitor-kutanga capacitor-run motors haabatanidzwe mumamiriro ezvinhu akasiyana-siyana ekudzora kukurumidza nekuti iwo ese ane pekutangira mhepo kana kubata kunoda kusvika 75% yekumhanya kwemota kuzere kusati kwatanga. mhepo yakavharwa, paKana uchidzora kumhanya, kazhinji kacho isingasviki 75%.Kana iyo yekutanga switch ikasavhurika, zvinobatika kana mhepo inotangira inopisa nekukasira uye mota inopisa nekumira.
Pakusarudza kuti ndeapi induction motors yekushandisa, kune nzira dzemuchina dzinobvumira mamotor aya kuti asvike pakumhanya kwawo, ayo anogona kushandiswa kana asina kumbononoka kudzoreredza mabhatani ekutanga panguva yekushanda kwakajairika.Iyo yakasara yemota, ine shaded pole, zvachose split capacitors uye polyphase, ndiyo yakanakisa sarudzo yekusarudza mota inozodzorwa nekukurumidza.Iyo ine shaded pole mota ndiyo yakanyanya hupfumi yevatatu kushandisa nekuda kweiyo dhizaini, asi inongowanikwa pasi pe1/4 horsepower.Iyo ine zvakare yakaderera yekutanga uye inomhanya torque uye haishande nekuda kwekugumira.Naizvozvo, kune imwechete-chikamu mashandiro ane anopfuura 1/4 simba uye / kana yakakwirira inoshanda torque, inogara yakapatsanurwa-chikamu capacitor motors inowanzoshandiswa.Mhando iyi yemota ndeimwe yeanodhura ega-phase motors, asi yakavimbika kwazvo, ine kumhanya kwakanaka uye kutanga kugona, uye inobvumira kumhanya kudzorwa nemagetsi. Zvisingaperi kupatsanura capacitor motors inoshanda padyo nematatu-chikamu mota. nzira yekushanda.
Matatu-phase motors anowanikwa mune ese ari maviri uye akazara bhiza simba, asi kazhinji, simba rekuchengetedza haripfuure mutengo wavo kudzamara vapinda muhuwandu hwebhiza.Inoshanda zvakangofanana neiyo imwe-phase mota, kwete imwe inopisa waya, asi matatu, iyo yekudzora kumhanya inoda kuve yakasiyana kubva kune imwechete-chikamu controller, uye mabasa eimwe-chikamu uye matatu-chikamu akasiyana zvishoma.
Pane kazhinji nzira ina dzekudzora kumhanya kwemota. Iyo yakapfava ndiyo inoshanduka inomhanya mota. Mapoka matatu asara ndeye passive mudziyo kumhanya kudzora, yakasimba mamiriro ekutonga uye michina michina. Imwe neimwe nzira yakasarudzika uye inowanikwa muindasitiri yese. use.Zvisinei nekushandisa, kazhinji tarisa nemugadziri wemota kuti nhanho yekudzora ndeyei, sezvo mamwe mamotor asina kugadzirirwa kudzora kumhanya.Zvakare, ziva nezvese zvine chekuita nekuchengetedza senge thermal overload dziviriro sechikamu cheiyo yekumhanyisa control system.Iko kunowanzo kuve nekupisa kwakawanda kunogadzirwa nemota, kana uchishandisa kukurumidza controller, kudzivirira tsaona kana kukuvara, zvinokurudzirwa kuti overload mudziviriri anogona kuva chikamu chemota kana controller pachayo.
mukupedzisa
Sekushandiswa kweinjini dzemaindasitiriyakashanduka nekufamba kwemakore, saka iva nenzira dzekudzora kumhanya, kuwana sarudzo chaiyo yekudzora kumhanya, rudzii rwemota yainokwanisa kugarisa, uye mari yekubhadhara/kushanda zvakanaka inosanganisirwa, vamwe vatongi vanogona kunge vasingadhure, Kwete semushandisi ane hushamwari. sevamwe vatongi, asi vachiri kuita kuti basa riitwe.
