1. Mhando dzenjanji dzemagetsi ekufambisa ngoro mota
Rail magetsi ekufambisa ngoro imhando yemidziyo inoshandiswa pakubata zvinhu uye kutakura. Mhando dzemota dzadzo dzakakamurwa kuita zvikamu zviviri: DC mota uye AC mota. DC mota dziri nyore uye dziri nyore kudzora uye dzinoshandiswa zvakanyanya munjanji magetsi ekufambisa ngoro; AC mota dzine zvakanakira mukushandiswa kwesimba uye kurodha huwandu, uye dzave dzichiwedzera kushandiswa zvakanyanya mumakore achangopfuura.
2. Kushanda nheyo yeDC motors
DC yemagetsi mota mota imhando yemidziyo inoshandura simba remagetsi kuita magetsi emagetsi. Kana yakananga ikozvino ichipfuura nepamhepo inomonereka, iyo armature mhepo inotenderera pasi pechiito chesimba remagineti, uye waya dziri mumhepo inotenderedza inokonzeresa mukana weiyo magineti, izvo zvinoita kuti kutungamira kweiyo armature mhepo inotenderera ikozvino ichinje. zvichikonzera kutenderera kwemagineti mune armature. Kune rimwe divi, iyo inotenderera yemagineti inotyaira iyo armature kutenderera, uye kune rimwe divi, inopindirana nekusingaperi magineti kuita kuti mota ishande zvakajairika.
Pane nzira mbiri dzekudzora dzeDC mota: yakananga voltage control uye PWM control. Direct voltage control haina kukwana uye inokodzera mamiriro apo kumhanya hakuchinji zvakanyanya; PWM kutonga inogona kuwana chiyero pakati pekushanda kwepamusoro uye hukuru hwekutakura. Naizvozvo, njanji yemagetsi ekufambisa ngoro mota dzinowanzo fambiswa nePWM kutonga kuti ive nechokwadi chekuenzanisa pakati pekuita nekuita.
3. Kushanda Nheyo ye AC Motor
AC mota mudziyo unofambiswa nealternating current. Zvinoenderana nehunhu hwematatu-phase alternating ikozvino, iyo yepakati inotenderera chikamu (kureva, rotor) ye AC mota ichatenderedzwa nemagetsi akazvimirira masimba. Kana simba rekubuda rikaedza kudhonza rotor, rinogadzira rotor ikozvino mumhepo inotenderera, iyo inoita kuti chikamu chemota chibudise imwe mutsauko wechikamu, nekudaro ichigadzira torque yakakura uye kutyaira njanji yemagetsi yekufambisa ngoro kuti imhanye.
AC mota dzinogona kudzorwa nevector control uye induction control. Vector control inogona kuwana akawanda anoburitsa torques uye kuvandudza kukwidziridza uye mutoro wemota; induction control yakakodzera kune yakaderera-kumhanya mamiriro, asi zvakare ine hunhu hweruzha rwakaderera. Mune njanji yemagetsi ekufambisa ngoro, nekuda kwekudiwa kwemutoro wakakwira, simba rakawanda, ruzha rwakaderera uye humwe hunhu, kutonga kwevector kunowanzoshandiswa kuwana kushanda kwakanaka uye kwakavimbika.
