Sezvo mota yazvino ichiwedzera, torque ichawedzerawo here?

Torque indekisi yakakosha yekuita yezvigadzirwa zvemota, iyo inoratidza zvakananga kugona kwemota kutyaira mutoro. Muzvigadzirwa zvemotokari, iyo yekutanga torque, yakayerwa torque uye yakanyanya torque inoratidza kugona kwemota munzvimbo dzakasiyana. Mhando dzakasiyana-siyana dzinoenderana neKunewo mutsauko mukuru muhukuru hwezvino, uye hukama huri pakati pehukuru hwezvino uye torque hwakasiyanawo pasi pepasi-mutoro uye mutoro wenyika dzemotokari.

Iyo torque inogadzirwa nemota panguva iyo voltage inoiswa kune mota yakamira inonzi kutanga torque.Saizi yekutanga torque yakaenzana nesquare yevoltage, inowedzera nekuwedzera kweiyo rotor kuramba, uye inoenderana nekudonha kwekuita kwemota.Kazhinji, pasi pemamiriro emagetsi akazara, iyo pakarepo yekutanga torque ye AC asynchronous mota inodarika 1.25 nguva yeiyo yakayerwa torque, uye inowirirana ikozvino inonzi kutanga ikozvino, iyo inowanzoita 5 kusvika 7 nguva dzeyakayerwa ikozvino.

Iyo mota iri pasi peiyo yakatemerwa inoshanda mamiriro inoenderana neyakayerwa torque uye yakayerwa ikozvino yemota, ayo ari akakosha paramita pasi peyakajairika kushanda mamiriro emota; apo motokari inoremerwa panguva yekushanda, inosanganisira iyo yakawanda torque yemotokari, iyo inoratidzira kupikisa kwemotokari Kukwanisa kwepamusoro kunopindirana nehukuru huripo pasi pemamiriro ekukwirira kwepamusoro.

Kune iyo mota yapera, hukama pakati peiyo electromagnetic torque yeasynchronous mota uye magineti flux uye rotor ikozvino inoratidzwa muformula (1):

Electromagnetic torque = inogara × magineti flux × inoshanda chikamu chechikamu chimwe nechimwe chazvino che rotor… (1)

Iyo inogona kuoneka kubva formula (1) kuti iyo electromagnetic torque yakanyatso kuenzana nechigadzirwa chemhepo gap flux uye inoshanda chikamu cheiyo rotor ikozvino.Iyo rotor yazvino uye stator yazvino inoteedzera hukama hwakatemerwa kutendeuka kwereshiyo, ndiko kuti, kana iyo magineti isingasviki pakuzara, iyo electromagnetic torque uye yazvino inowirirana. Iyo yakanyanya torque ndiyo yepamusoro kukosha kweiyo mota torque.

Iyo yepamusoro yemagetsi torque ine kukosha kukuru kune mota.Kana iyo mota ichimhanya, kana mutoro wacho ukangoerekana wawedzera kwenguva pfupi uye wodzokera kune wakajairika mutoro, chero bedzi iyo yakazara braking torque isiri yakakura kupfuura yakanyanya electromagnetic torque, mota inogona kuramba ichimhanya yakadzikama; kana zvisina kudaro, mota inomira.Zvinogona kuonekwa kuti iyo yakakura yemagetsi torque yemagetsi, iyo yakasimba yenguva pfupi yekuremedza simba remota, saka kuwandisa kwemota kunoratidzwa nereshiyo yehukuru hwemagetsi torque kune yakayerwa torque.
