Sei kushanda zvakanaka kwemamota emagineti anogara aripo kwakakwira?

Mota yemagetsi inogara kwenguva refu ine magineti akafanana inonyanya kugadzirwa ne stator, rotor uye housing components. Kufanana nemota dzeAC dzakajairika, stator core yakagadzirwa ne laminated structure kuderedza kurasikirwa kwesimbi kunokonzerwa ne eddy current uye hysteresis effect panguva yekushanda kwemota; ma windings anowanzo kuve e three-phase symmetrical structure, asi sarudzo yema parameter yakasiyana zvikuru. Chikamu che rotor chine chimiro chakasiyana, kusanganisira permanent magnet rotor ine starter squirrel-cage, pamwe ne embedded kana surface-mounted pure permanent magnet rotor. Rotor core inogona kugadzirwa ne solid structure kana laminated structure. Rotor ine magineti anogara kwenguva refu, ayo anowanzonzi magnetic steel.

Mukushanda kwakajairika kwemota yemagineti inogara kwenguva refu, minda yemagineti yerotor neye stator iri muchimiro che synchronous. Hapana induced current muchikamu cherotor, uye nekudaro hapana rotor copper loss kana hysteresis uye eddy current loss. Hapana chikonzero chekufunga nezvedambudziko rekupisa rinokonzerwa nekurasikirwa kwerotor. Kazhinji, magineti anogara kwenguva refu anofambiswa nema frequency converters akatsaurirwa, ayo ane mabasa ekutanga zvinyoro. Pamusoro pezvo, magineti anogara kwenguva refu imota dzinoenderana uye dzine hunhu hwemagineti anogara kwenguva refu zvekuti power factor inogona kugadziriswa kune kukosha kwakatsanangurwa kuburikidza nesimba re excitation. Nokudaro, power factor inogona kugadzirwa kune kukosha kunodiwa.
Kubva pamaonero ekutanga, nekuda kwemamiriro chaiwo apo mota dzemagineti dzinogara kwenguva refu dzinotanga nemagetsi ekushandura mafrequency kana ma frequency converters anoenderana, maitiro ekutanga emota dzemagineti dzinogara kwenguva refu ari nyore kwazvo kuita; zvakafanana nekutanga kwemota dzekushandura mafrequency, zvinodzivirira zvikanganiso zvekutanga zvemota dzemagineti dzakajairwa dzesquirrel-cage asynchronous.

Mukupedzisa, kushanda nesimba kwemota dzemagineti dzinogara kwenguva refu kunogona kusvika padanho repamusoro. Maumbirwo adzo ari nyore uye dzave dzakakurumbira mumusika mumakore gumi apfuura. Zvisinei, demagnetization fault idambudziko risingadzivisike kune magineti dzinogara kwenguva refu. Kana magetsi akawandisa kana tembiricha yakakwira zvakanyanya, tembiricha yekumonera kwemota inokwira zvakanyanya nekukasira, magetsi anokwira zvakanyanya, uye magineti anogara kwenguva refu anobvisa magineti nekukurumidza. Mukudzora magineti emagetsi anogara kwenguva refu, mudziyo wekudzivirira magetsi akawandisa unogadzirwa kudzivirira dambudziko rekumonera kwemota kutsva. Zvisinei, izvi zvinotungamira mukumonera kwemagetsi nekudzimwa kwemidziyo.
