[Ukwabelana ngoLwazi] Kutheni le nto iipali zemagnethi zeDC ezisisigxina zisebenzisa imagnethi ezixande?

I-exciter encedisa umazibuthe esisigxina luhlobo olutsha lwe-rotor yangaphandle ye-DC esisigxina ye-magnetic motor. Umsesane wayo wokukrwitsha ojikelezayo uxhonywe ngokuthe ngqo kwi-shaft. Kukho iipali zemagnethi ezingama-20 kwiringi. Ipali nganye inesihlangu sepali esidityanisiweyo. Umzimba wepali wenziwe ngeziqwenga ezintathu ezixande. Yenziwe ngentsimbi yamagnetic kwaye idityaniswe ngokupheleleyo kunye ne "914" glue. Umzimba wepali usongelwe kwaye uqiniswe ngeeribhoni zeglasi ezingenabubanzi ukwenza umkhono okhuselayo. Umzimba ngamnye wepali kunye nesihlangu sepali zenziwe ngamaqhekeza amabini amabalaintsimbi encinci.

Kwimotor yemagnethi esisigxina yeDC, xa ezinye iiparamitha zihlala zingatshintshi, ukuphakama kwemagnethi eshiyekileyo yemagnethi, incinci yangoku, kwaye isantya sisezantsi. Oku kuchanekile. Ukusuka koku, unokuhlalutya ngokwakho ukuba yeyiphi imagnethi yeeprototypes zakho ezimbini ezingcono. Imagnethi eshiyekileyo inkulu.Ngokubhekiselele kumgaqo-siseko, xa ezinye iiparamitha zihlala zingatshintshi, ukuphakama kwemagnethi eshiyekileyo yemagnethi, ubukhulu be-magnetic flux yepole nganye yemoto. Ngokwefomula yesantya semoto ye-DC n=(U-IR)/CeΦ≈U/CeΦ, inokuba kakhulu Kulula ukugqiba ukuba i-Φ enkulu, isantya esisezantsi. Isantya esisezantsi, incinci ilahleko engenamthwalo, kwaye incinci ikhoyo ngoku akukho mthwalo.

I-torque etshixiweyo ye-DC yemagnethi esisigxina yemoto inxulumene nobukhulu bemagnethi kunye namandla omhlaba wemagnethi. Ukuba ubukhulu bunokutshintsha amandla ombane wamagnetic, kuya kufaneleka. Ngexesha lenkqubo yendibano umazibuthe wemagnethi egxininiswe esisigxina, ukuba isetyenziswa ngesandla Ukusebenzisa iglu kumphezulu wemagnethi kwenza kube nzima ukuba umqhubi abambe umazibuthe. Kwangaxeshanye, ngenxa yokungafezeki kobuchwephesha obukhoyo xa ufaka umazibuthe kwi-slot, ukukhuhlana nodonga lwe-slot kuya kwenzeka ngokuqinisekileyo. Ngaphaya koko, Iglu kumphezulu wentsimbi yemagnethi esetyenziswa ngesandla kwaye inendawo encinci yokugquma iglu ayisasazwa ngokulinganayo, okukhokelela ekuncamatheleni okungalunganga, kwaye intsimbi enozibuthe inokuwa ngexesha lokusetyenziswa kamva.
