Ndeipi motokari yekusimudzira, chii chaicho chaicho?

Iyo motokari inoshandiswa isimbi yakagadzirwa nema electromechanical iyo inoshandura kushandiswa kwemagetsi mune imwe discrete mechanical movement. Iyi nzira haisi yakasiyana nedzimwe motori dzemagetsi. Kazhinji, chigadziro chechikamu chino chinosanganisira motokari yemotokari, shaft uye endals. Zvose izvi zvinosanganiswa kuva muhombe huru (zvisingawanzi rectangular) muviri.

Chikamu chekushandiswa

Stepper motokari inogona kushandiswa mune zvakasiyana-siyana zvemabhizimisi. Kazhinji kacho, motokari dzakadaro dzinowanikwa pamichina yekushanda uye magetsi ehofisi, zvakadai semichina yefeksi, printers uye disk drives.

Iye zvino mhando dzinoverengeka dzejini idzi dzinobudiswa, kuitira kuti inoshanda zvakanaka, imwe neimwe inofanira kusarudza purogiramu yake uye mutemo wekutyaira.

Batsirwa

Chokutanga, motokari inopinda inonyanya kuvimbika. Izvi zvinokonzerwa nekuti muzvigadzirwa zvayo hapana mazai e graphite, ayo anowanzoshandiswa mumotokari yemotokari uye ane hupenyu hwehupenyu hupfupi. Kudzora motokari yekusimudza kunogadzirwa nekutakura, saka kuti vangashanda zvakadini, iyo injini ichashanda. Chechipiri, iyi nzira inoratidzwa nekuisa pasina mhinduro. Izvi zvinogadziriswa nekuda kwekutenderera kwechigaro chechikamu pane zvinenge zvichitsvaga. Chechitatu, motokari yekusimudzira imwe yezvigadzirwa zvishoma zvinopa kukurumidza kukurumidza, kumisa uye kuchinja kwehutano hwose. Muchiitiko ichi, motokari inopa nguva yakazara muimira mode. Uyewo iyi motokari inoratidzwa nekudzoka kwakakwana nekuisa. Injini dzemazuva ano dzinoshanda nekururamisa kwemazana mana kubva muzana yehutatu hwemafuro, uye kukanganisa hakugoni kuitika panguva yebasa ravo kubva pane imwe nhanho kusvika kune imwe.

Kukanganisika

Pane zvakawanda zvisingabatsiri kune ichi chigadzirwa, asi zvishoma pane zvinobatsira. Pakati pezvimwe zvipingamupinyi zvikuru, zvinofanira kuonekwa kuti chokwadi kuti aya motokari anozivikanwa nechishamiso che resonance. Vanogonawo kurasikirwa nekutonga kwechigaro nekuda kwekushanda pasina mhinduro. Pamusoro penguva refu, motokari inotsika haisi yakanyatsobudirira, kunyange zvazvo iri muitiro wekushanda haina kusiyana nesimba. Nenzira, kunyange pasina kuve pasi pemutoro, inoramba ichiwana magetsi, uye mune imwechete yakafanana sepamberi paunenge uchishanda. Nemhaka yekuoma kwakaoma dunhu, chigadzirwa ichi chakaoma kugadzirisa pachako.

Ndechipi musiyano pakati pemotokari yekusimudzira uye servomotors?

Usavhiringidza nzira idzi mbiri. Pasinei nokuti zvose zviri zviviri zvakagadzirwa nenzira yakafanana uye inoshandiswa pakushanda, nenzira dzakawanda dzinopesana pakati pavo. Mhedzisiro huru ndeyokuti motokari inofamba inogona kupa 1 rotor revolution mune dzimwe nhanho. Muchiitiko ichi, chigadzirwa ichi chinoratidzirwa nekushanda kwayo uye kushandura kwechinyorwa. Servomotors vane mumagariro avo anonyatsoziva ma sensor anoona kukurumidza uye chinzvimbo chechigadziro chekutonga. Sezvazviri pano apa resolver kana encoder.
