Chii chinonzi mota?
Michina yemagetsi inoreva mudziyo wemagetsi unoona shanduko yemagetsi kana kutapurirana zvinoenderana nemutemo wemagetsi induction.Iyo mota inomiririrwa netsamba M (yekare standard D) mudunhu, uye basa rayo guru nderekugadzira kutyaira torque.Sesimba remagetsi emidziyo yemagetsi kana michina yakasiyana-siyana, jenareta inomiririrwa netsamba G mudunhu, uye basa rayo guru nderekushandura simba remagetsi kuita magetsi emagetsi.

A, kupatsanurwa kwemota uye kupatsanura
1. Zvinoenderana nerudzi rwemagetsi ekushanda, anogona kukamurwa kuita DC mota uye AC mota.
2. Zvinoenderana nechimiro uye nheyo yekushanda, inogona kukamurwa kuita DC mota, asynchronous mota uye synchronous mota.
3. Zvinoenderana nekutanga uye kumhanya modes, inogona kukamurwa kuita mhando nhatu: capacitor-kutanga single-phase asynchronous mota, capacitor-running single-phase asynchronous mota, capacitor-kutanga single-phase asynchronous mota uye split-phase single- phase asynchronous mota.
4. Zvinoenderana nechinangwa, inogona kukamurwa kuita kutyaira mota uye kutonga mota.
5. Zvinoenderana nechimiro che rotor, inogona kukamurwa kuita squirrel-cage induction mota (yekare chiyero chinonzi squirrel-cage asynchronous mota) uye ronda rotor induction mota (yekare chiyero chinonzi ronda asynchronous mota).
6. Zvinoenderana nekumhanya kwekumhanya, inogona kukamurwa kuita yakakwira-speed mota, yakaderera-speed mota, inogara-speed mota uye variable-speed mota.Low-kumhanya mota dzakakamurwa kuita giya rekudzikisa mota, magetsi ekudzikisa mota, torque mota uye claw-pole synchronous motors.
Chechipiri, chii chinonzi injini?
Motokari imhando yemidziyo inoshandura simba remagetsi kuita mechanical simba.Inoshandisa coil yemagetsi (kureva, stator winding) kugadzira inotenderera magineti uye kuita pa rotor (senge squirrel-cage yakavharwa aluminium furemu) kugadzira magnetoelectric inotenderera torque.Mota dzakakamurwa kuita DC mota uye AC mota zvinoenderana neakasiyana magetsi masosi.Mazhinji emotor ari musimba remagetsi ma AC motors, anogona kunge ari synchronous motors kana asynchronous motors (iyo stator magineti kumhanya kwemota hairambe ichienderana neiyo rotor kutenderera kumhanya).Iyo mota inonyanya kuumbwa ne stator uye rotor, uye kutungamira kweiyo ine simba conductor mundima yemagineti ine hukama negwara reazvino uye magineti induction mutsara (magnetic field direction).Nheyo yekushanda yemota ndeyekuti iyo magineti inoshanda pane yazvino kuita kuti mota itenderere.
Chechitatu, chimiro chekutanga chemotokari
1. Chimiro chetatu-phase asynchronous mota ine stator, rotor uye zvimwe zvinhu.
2. Iyo DC mota inotora octagonal yakazara laminated chimiro uye yakatevedzana excitation winding, iyo inokodzera otomatiki kudzora tekinoroji inoda kumberi uye kumashure kutenderera.Zvinoenderana nezvinodiwa nevashandisi, inogona zvakare kuitwa kuita inoteedzana inotenderera.Motokari dzine hurefu hwepakati hwe100 ~ 280mm hadzina muripo wekupopota, asi mota dzine urefu hwepakati hwe250mm uye 280 mm dzinogona kugadzirwa nemhepo yemuripo zvichienderana nemamiriro ezvinhu uye zvinodiwa, uye mota dzine hurefu hwepakati hwe315 ~ 450 mm dzine mhepo yekuripira.Iwo ekuisa zviyero uye tekinoroji zvinodiwa zvemotor ine kureba kwepakati pe500 ~ 710 mm inosangana neIEC yepasi rose zviyero, uye iyo mechanic dimension kushivirira kwemota inosangana neISO yenyika dzese.
Pane musiyano uripo pakati pemota nemota?
Motokari inosanganisira injini uye jenareta.Iyo floorboard yejenareta uye mota, izvo zviviri zvine pfungwa dzakasiyana.Iyo mota ingori imwe yemamodhi ekushanda kwemota, asi mota inoshanda mumagetsi emagetsi, ndiko kuti, inoshandura simba remagetsi kuita mamwe marudzi esimba;Imwe nzira yekushanda yemota ndiyo jenareta.Panguva ino, inoshanda mumagetsi ekugadzira modhi uye inoshandura mamwe marudzi esimba kuita simba remagetsi.Nekudaro, mamwe mota, senge masynchronous motors, anowanzo shandiswa sejenareta, asi anogona zvakare kushandiswa zvakananga semotor.Asynchronous motors anonyanya kushandiswa kune mota, asi anogona zvakare kushandiswa semajenareta nekuwedzera akareruka peripheral components.
