Motokarishaft inogadziriswa kuitira kuti irege kutenderera, uye ikozvino inosimbiswa. Panguva ino, ikozvino ndiyo yakakiyiwa rotor ikozvino. General AC mota, kusanganisira frequency modulation motors, haibvumidzwe kumira.Zvinoenderana neiyo yekunze hunhu curve ye AC mota, kana mota ye AC yakavharwa, "kupidigura ikozvino" kunogadzirwa kupisa mota.
Iyo yakavharwa-rotor ikozvino uye yekutanga ikozvino yakaenzana mukukosha, asi nguva yemotokari inotanga ikozvino uye yakavharwa-rotor ikozvino yakasiyana. Iyo yakanyanya kukosha yekutanga ikozvino inooneka mukati me 0.025 mushure mekunge mota yaiswa simba, uye inoora zvakanyanya nekufamba kwenguva. , kukurumidza kuora kwakabatana nenguva inoramba iripo yemotokari; nepo iyo yakakiyiwa-rotor ikozvino yemota isingaori nekufamba kwenguva, asi inoramba iripo.
Kubva pakuongorora mamiriro emota, tinogona kuipatsanura kuita matunhu matatu: kutanga, kuyera kushanda uye kuvhara. Maitiro ekutanga anoreva maitiro ekuchinja rotor kubva kune static kuenda kune yakayerwa yekumhanyisa mamiriro kana mota yapihwa simba.
Nezve motor kutanga ikozvino
Ikozvino yekutanga ndiyo ikozvino inoenderana nekushandurwa kwe rotor kubva kune yakadzikama kuenda kune inomhanya mamiriro panguva iyo mota inopihwa simba pasi pemamiriro eiyo rated voltage. Ndiyo nzira yekushandura mamiriro ekufambisa kwemotokari rotor, kureva, kushandura inertia ye rotor, saka ikozvino inopindirana ichave yakakura.Kana uchitanga zvakananga, kutanga ikozvino kwemota kunowanzo 5 kusvika ku7 nguva yakayerwa ikozvino.Kana iyo yekutanga ikozvino yemota yakakura kwazvo, ichave neyakakura yakashata kukanganisa kumuviri wemota uye gidhi remagetsi. Naizvozvo, kune mahombe uye epakati-saizi mota, yekutanga ikozvino inoganhurwa kusvika kanokwana kaviri iyo yakayerwa ikozvino nenzira yekunyorova kutanga. Iko kuenderera mberi kwekuvandudza kweiyo mota control system uye dzakasiyana nzira dzekutanga dzakadai seyachinja frequency kutanga uye nhanho-pasi kutanga zvakagadzirisa zvirinani dambudziko iri.
About motor stall current
Chaizvoizvo, zvinogona kunzwisiswa kuti iyo yakakiyiwa rotor ikozvino ndiyo yazvino kuyerwa kana rotor ichichengetwa yakamira, uye mota yakakiyiwa rotor inzvimbo iyo mota ichiri kuburitsa torque kana kumhanya kuri zero, iyo inowanzo mechanical kana yekugadzira.
Kana mota yaremerwa, muchina unotyairwa unotadza, kutakura kwakuvadzwa, uye mota ikatadza kutsvaira, mota inogona kusakwanisa kutenderera.Kana iyo mota yakavharwa, simba rayo rakadzika zvakanyanya, uye yakakiyiwa rotor ikozvino yakakura, uye iyo mota inotenderera inogona kupiswa kunze kwenguva yakareba.Nekudaro, kuti uedze mamwe maitiro emota, zvinodikanwa kuita bvunzo pamota, iyo inoitwa mune ese ari maviri emhando bvunzo uye yekuongorora bvunzo yemota.
Iyo yakakiyiwa-rotor bvunzo inonyanya kuyera yakakiyiwa-rotor ikozvino, yakakiyiwa-rotor torque kukosha uye yakakiyiwa-rotor kurasikirwa payakayerwa voltage. Kuburikidza nekuongororwa kweiyo yakavharwa-rotor ikozvino uye matatu-chikamu chiyero, inogona kuratidza stator uye rotor windings yemotokari, pamwe chete ne stator uye rotor. Iko kunzwisisika kweiyo yakagadzirwa magineti wedunhu uye mamwe matambudziko emhando.
Munguva yekuyedzwa kwerudzi rwemota, kune akawanda mavoltage akayerwa neyakavharwa-rotor bvunzo. Kana mota ichiyedzwa pafekitori, poindi yemagetsi inosarudzwa kuyerwa. Kazhinji, magetsi ekuedzwa anosarudzwa zvichienderana nechikamu chimwe chete chechina kusvika pachikamu chimwe chete cheshanu cheyero yakayerwa yemota, sekuti Kana iyo yakatemerwa voltage iri 220V, 60V inosarudzwa zvakafanana seyeyedzo voltage, uye kana yakayerwa voltage iri 380V, 100V inosarudzwa seyeyedzo voltage.
