Pane musiyano mukuru pakati pemota nemagetsi mota. Nhasi tichatarisa mimwe misiyano pakati pezviviri izvi towedzera kusiyanisa kusiyana pakati pazvo.
Chii chinonzi mota yemagetsi?
Mota yemagetsi mudziyo wemagetsi unoshandura kana kufambisa simba remagetsi zvinoenderana nemirairo yemagetsi induction.
Motokari inomiririrwa nebhii M mudunhu (D mune yekare chiyero) uye basa rayo guru nderekugadzira kutyaira torque sesimba remagetsi emidziyo kana michina yakasiyana, nepo jenareta inomiririrwa netsamba G mudunhu uye basa rayo guru nderekushandura simba remagetsi kuita magetsi emagetsi.
一. Motor division uye classification
1. Maererano nemhando yekushanda kwesimba rekushandisa: inogona kugoverwa kuvaDC motauye AC mota.
2. Maererano nechimiro uye nheyo yekushanda, inogona kugoverwa kuvaDC mota, asynchronous mota uye synchronous mota.
3. Maererano nekutanga uye kumhanya maitiro: capacitor kutanga single-phase asynchronous motor, capacitor inoshandisa single-phase asynchronous motor, capacitor kutanga uye kushanda imwe-phase asynchronous motor uye split-phase single-phase asynchronous motor.
4. Zvinoenderana nechinangwa, mota inogona kukamurwa kuita: mota yekutyaira uye mota yekudzora.
5. Maererano nechimiro che rotor: cage induction motor (yekare chiyero chinonzi squirrel cage induction motor) uye ronda rotor induction motor (yekare inonzi ronda asynchronous motor).
6. Maererano nekukurumidzira kwekushanda, vanogona kugoverwa kuva: ma-motor-speed, akadzika-speed motors, anogara ari-speed motors uye anomhanya-anotungamirirwa. Low-speed motors akakamurwa kuita giya mota, electromagnetic kuderedza mota, torque mota uye claw-pole synchronous motors.
二. Chii chinonzi mota yemagetsi
Mota yemagetsi (Motor) chishandiso chinoshandura simba remagetsi kuita simba remagetsi. Iko kushandiswa kwemakoiri ane simba (anozivikanwawo se stator windings) kugadzira inotenderera yemagineti uye kuita pane rotor (senge squirrel cage yakavharwa aruminiyamu furemu) kugadzira magnetoelectric simba rinotenderera torque. Magetsi mota dzakakamurwa kuitaDC motauye AC motors maererano nemagetsi anoshandiswa. Mazhinji emagetsi emagetsi masisitimu emagetsi ma AC motors, ayo anogona kuenderana kana asynchronous (iyo mota stator magineti kumhanya uye inotenderera inotenderera kumhanya haichengetedze synchronous kumhanya). Motokari yemagetsi inosanganisira kunyanya stator uye rotor. Kutungamira kwekufamba kwewaya ine simba mundima yemagineti kune hukama negwara rezvino uye kutungamira kwemagineti induction mitsara (magnetic field direction). Nheyo yekushanda yemota ndeyekuti iyo magineti inoshanda sesimba pane yazvino, zvichiita kuti mota itenderere.
三、 Iyo yakakosha chimiro chemagetsi mota
1. Chimiro chetatu-phase asynchronous motor inosanganisira stator, rotor uye zvimwe zvinhu.
2. Iyo DC mota ine octagonal, yakazara laminated chimiro neyakatevedzana excitation winding, iyo yakakodzera kune otomatiki kudzora tekinoroji uko kumberi uye kumashure kutenderera kunodiwa. Ivo vanogona zvakare kugadzirwa neakateedzana-inofadza windings zvinoenderana nezvinodiwa nevatengi. Mota dzine hurefu hwepakati hwe100 kusvika 280 mm hadzina muripo wekupoterera, asi mota dzine hurefu hwepakati hwe250 mm uye 280 mm dzinogona kugadzirwa nemhepo yekuripa zvinoenderana nemamiriro ezvinhu uye zvinodiwa, uye mota dzine hurefu hwepakati hwe315 kusvika 450 mm dzine muripo wemhepo. Zviyero uye tekinoroji zvinodiwa zvemotor dzine kureba kwepakati pe500-710mm zvinoenderana neIEC yepasirese mwero, uye iyo mechanic dimensional kushivirira kwemamotor inoenderana neISO yepasi rose zviyero.
Pane musiyano uripo pakati pemota nemagetsi mota?
Magetsi emagetsi anosanganisira ese ari maviri mota uye jenareta. Iri izwi rejenareta uye mota, uye izvo zviviri zvinosiyaniswa nemusiyano. Injini yemagetsi inongova imwe yenzira dzekushanda kwemotokari, asi inoshanda mumagetsi emagetsi, zvinoreva kuti simba remagetsi rinoshandurwa kuva mamwe maitiro emagetsi; imwe nzira yekushanda kwemotokari ijenareta, inoshanda mumagetsi ekugadzirwa kwemagetsi, kushandura mamwe maitiro esimba kuita simba remagetsi. Nekudaro, mamwe mamotor senge masynchronous motors anowanzo shandiswa sejenareta, asi anogona zvakare kushandiswa zvakananga semagetsi emagetsi. Asynchronous motors anowanzo shandiswa semagetsi emagetsi, asi, pamwe nekuwedzera kwezviri nyore peripheral zvikamu, zvinogona zvakare kushandiswa sejenareta.
