Chii chinonzi brushless mota uye chinoshanda sei?

Chii chinonzi brushless mota uye chinoshanda sei?Tichapindura mibvunzo iyi munyaya ino.

Munguva yemazuva ano maturusi emagetsi uye gadget, hazvishamisi kuti brushless motors dziri kuwedzera kuwanda muzvigadzirwa zvatinotenga.Kunyangwe iyo brushless mota yakagadzirwa pakati pezana ramakore rechi 19, yanga isingaite zvekutengesa kusvika 1962.

Brushless mota, nekuda kwekuita kwayo kwepamusoro, kufambisa torque yakatsetseka, kusimba kwepamusoro uye kumhanya kwakanyanya, iri kutsiva mota yekudhirowa zvishoma nezvishoma.Zvikumbiro zvavo, munguva yakapfuura, zvakaganhurirwa zvakanyanya nemitengo yekuwedzera yeakaoma mota controller, ayo anodiwa kuti ashandise mota.

Kushanda kwemukati kwemainjini maviri kwakafanana.Kana coil yemotor ichipihwa simba, inogadzira yechinguvana magineti inodzinga kana kukwezva magineti anogara.

Simba rinobuda rinobva rashandurwa kuita kutenderera kweshaft kuti mota ishande.Sezvo shaft inotenderera, ikozvino inotungamirirwa kune zvakasiyana-siyana, kuitira kuti magnetic field irambe ichikwezva uye inodzingwa, ichibvumira rotor kutenderera nguva dzose.

Iyo brushless mota inoshanda zvakanyanya kupfuura iyo yekudhirowa mota mukuita kushandura simba remagetsi kuita mechanic simba.Ivo vanoshaya commutator, iyo inoderedza kuchengetedza uye kuoma, uye inoderedza kukanganiswa kwemagetsi.

Ivo vanogona kukudziridza yakakwira torque, yakanaka yekumhanyisa mhinduro, uye inogona kudzora nyore chip imwechete (motor control unit).

Ivo zvakare vanoshanda mukati mehupamhi hwekumhanya, vachibvumira yakanaka kufamba kwekutonga uye torque pakuzorora.

Brushless mota uye waya yekudhirowa mota zvakasiyana zvakanyanya muchimiro.

Iyo bhurashi inoshandiswa pane bhurashi mota kuendesa ikozvino kune inotenderera kuburikidza nema commutator contacts.

Nekudaro, iyo brushless mota haidi commutator.Iyo mota yemagineti inochinjirwa neamplifier inokonzereswa neinodzosera mudziyo.Muenzaniso ndeye optical encoder inoyera mafambiro akanaka nekuti iwo haana kutsamira pachikamu chekufamba.

Iwo mahwindi ari pamota yekudhirowa ari pane rotor uye iwo ari pane brushless mota stator.Kudiwa kwebhurashi kunogona kubviswa nekutsvaga coil pane yakamira chikamu che stator kana mota.

Muchidimbu, mutsauko mukuru pakati pebrashi isina mota uye mota yakabhurwa ndeyekuti hapana magineti akagadziriswa uye waya dzinotenderera (brushed), uye mabhurashi emagetsi ane waya akagadziriswa uye anotenderera magineti.Mukana mukuru ndeye brushless mota isina kukweshera, nekudaro kuderedza kupisa uye kuvandudza kushanda kwese.
