High Speed AC Motor
AC motamudziyo unoshandura simba remagetsi rekuchinjanisa ikozvino kuita simba remagetsi.Injini ye AC inonyanya kuve nemagetsi emagetsi emagetsi emagetsi kana kuparadzirwa stator mhepo inoshandiswa kugadzira magineti uye inotenderera armature kana rotor.Iyo mota inogadzirwa nekushandisa chiitiko chekutenderedza coil ine simba mune remagineti nechisimba.Kune mhando mbiri dze AC mota: synchronous AC mota uye induction mota.
Iyo stator mhepo yechitatu-chikamu AC mota ndeye matatu makoiri akapatsanurwa ne120 madhigirii kubva kune mumwe, ayo akabatanidzwa mune matatu kana nyeredzi chimiro.Kana matatu-phase ikozvino yashandiswa, magineti inogadzirwa mune yega coil, uye matatu magineti minda inosanganiswa kuti iwane inotenderera yemagineti.
AC motaine stator uye rotor, uye kune marudzi maviri e AC mota: synchronous AC mota uye induction mota.Marudzi ese ari maviri emotor anogadzira inotenderera magineti nekupfuura AC ikozvino mune stator mhepo, asi iyo rotor mhepo yesynchronous AC mota inowanzoda kupihwa neDC yazvino (excitation yazvino) neiyo exciter, nepo rotor mhepo yeinduction mota isingaite. zvinoda kudyiswa nezvino.
Iyo stator mhepo yechitatu-chikamu AC mota ndeye matatu makoiri akapatsanurwa ne120 madhigirii kubva kune mumwe uye akabatana mune yetatu kana nyeredzi chimiro.Kana iyo yechitatu-chikamu ikozvino inoshandiswa, magnetic field inogadzirwa mune imwe neimwe coil, uye minda mitatu inosanganiswa kuti iwane munda unotenderera.Kana iyo yazvino inopedza kuzunguzika kumwechete kwakazara, iyo inotenderera yemagineti inotenderera chaizvo vhiki imwe, saka, mabhindauko paminiti yeinotenderera magineti N=60f.Iyo equation f ndiyo frequency yemagetsi ekupa.
AC motors inogona kuiswa mumagetsi esynchronous uye asynchronous motors (kana asiri-synchronous motors) zvichienderana nechiyero chekutenderera.Iyo rotor inomhanya yeinjiniya inogara yakangofanana nekumhanya kweiyo inotenderera magineti pasinei nemutoro, saka iyi inomhanya inonzi synchronous speed, uye sezvataurwa pamusoro apa, inotarirwa chete nehuwandu hwemagetsi.Iyo inomhanya yeasynchronous mota haisi nguva dzose, asi zvinoenderana nehukuru hwemutoro uye voltage yemagetsi.Pakati pematatu-chikamu asynchronous motors, pane asiri-rectifier mota uye anogadzirisa mota.Mazhinji easynchronous motors mukuita induction motors isina rectifier (asi inofananidzwa uye inoteedzana matatu-chikamu asynchronous rectifier motors ane zvakanakira zvinogadziriswa kumhanya muhupamhi uye yakakwirira simba chinhu), uye kumhanya kwayo kunogara kuri kushoma pane iyo synchronous kumhanya. .
Main applications
AC motaine hunyanzvi hwekushanda kwepamusoro, uye haina utsi, huruva uye kunhuwa, haina kusvibisa nharaunda, uye ruzha rushoma.Nekuda kweakatevedzana mabhenefiti, inoshandiswa zvakanyanya muzvinhu zvakasiyana senge maindasitiri nekurima kugadzirwa, zvekufambisa, kudzivirira kwenyika, zvekutengesa uye zvemumba, midziyo yemagetsi yekurapa, nezvimwe.
