Kodi mota ndi chiyani?
Makina amagetsi amatanthauza chipangizo chamagetsi chomwe chimazindikira kutembenuka kwamagetsi kapena kufalitsa molingana ndi lamulo la electromagnetic induction.Galimotoyo imayimiridwa ndi chilembo M (kale D) muderali, ndipo ntchito yake yayikulu ndikupanga torque yoyendetsa.Monga gwero la mphamvu zamagetsi zamagetsi kapena makina osiyanasiyana, jenereta imayimiridwa ndi chilembo G mu dera, ndipo ntchito yake yaikulu ndikutembenuza mphamvu yamagetsi kukhala mphamvu yamakina.

A, kugawanika kwa magalimoto ndi magulu
1. Malingana ndi mtundu wa magetsi ogwira ntchito, amatha kugawidwa mu DC motor ndi AC motor.
2. Malinga ndi kapangidwe kake ndi mfundo yogwirira ntchito, imatha kugawidwa kukhala mota ya DC, mota ya asynchronous ndi motor synchronous.
3. Malinga ndi njira zoyambira ndi zoyambira, zitha kugawidwa m'mitundu itatu: mota ya capacitor-yoyambira imodzi-gawo asynchronous motor, capacitor-yoyendetsa imodzi-gawo asynchronous motor, capacitor-starting single-phase asynchronous motor and split-phase single- gawo asynchronous motor.
4. Malinga ndi cholinga, itha kugawidwa kukhala galimoto yoyendetsa ndi kuyendetsa galimoto.
5. Malinga ndi kapangidwe ka rotor, imatha kugawidwa kukhala gologolo-khola induction motor (muyezo wakale wotchedwa gologolo-cage asynchronous motor) ndi bala rotor induction motor (muyezo wakale wotchedwa bala asynchronous motor).
6. Malinga ndi liwiro lothamanga, imatha kugawidwa m'magalimoto othamanga kwambiri, othamanga kwambiri, othamanga kwambiri komanso othamanga.Ma motors othamanga kwambiri amagawidwa kukhala ma mota ochepetsa magiya, ma electromagnetic reduction motors, torque motors ndi claw-pole synchronous motors.
Chachiwiri, injini ndi chiyani?
Motor ndi mtundu wa zida zomwe zimatembenuza mphamvu yamagetsi kukhala mphamvu yamakina.Amagwiritsa ntchito koyilo yamagetsi (ndiko kuti, mafunde a stator) kuti apange mphamvu ya maginito yozungulira ndikuchitapo kanthu (monga squirrel-cage shut aluminium frame) kuti apange torque yozungulira ya magnetoelectric.Ma motors amagawidwa kukhala ma motors a DC ndi ma AC motors kutengera magwero amagetsi osiyanasiyana.Ma motors ambiri mumagetsi amagetsi ndi ma AC motors, omwe amatha kukhala ma motors ofananira kapena ma asynchronous motors (kuthamanga kwa maginito kwa stator sikumayenderana ndi liwiro lozungulira).Galimotoyo imapangidwa makamaka ndi stator ndi rotor, ndipo mayendedwe a kondakitala wopatsa mphamvu mu gawo la maginito amagwirizana ndi momwe mzere wamakono ndi maginito olowera (magnetic field direction).Mfundo yogwirira ntchito ya injini ndikuti mphamvu ya maginito imagwira ntchito pakalipano kuti injiniyo izungulire.
Chachitatu, kapangidwe kake ka injini
1. Kapangidwe ka atatu-gawo asynchronous motor imakhala ndi stator, rotor ndi zina zowonjezera.
2. The DC galimoto utenga octagonal mokwanira laminated kapangidwe ndi mndandanda kukomerera mapiringidzo, amene ali oyenera kulamulira luso luso kuti amafunikira kutsogolo ndi m'mbuyo kasinthasintha.Malinga ndi zosowa za ogwiritsa ntchito, imathanso kupangidwa kukhala mafunde angapo.Ma motors okhala ndi kutalika kwapakati kwa 100 ~ 280mm alibe mapindikidwe olipira, koma ma mota omwe ali ndi kutalika kwapakati kwa 250mm ndi 280 mm amatha kupangidwa ndi chipukuta misozi molingana ndi mikhalidwe ndi zosowa, ndipo ma mota okhala pakati pa 315 ~ 450 mm amakhala ndi chipukuta misozi.Miyeso yoyika ndi zofunikira zaukadaulo zamagalimoto okhala ndi kutalika kwa 500 ~ 710 mm zimakumana ndi miyezo yapadziko lonse lapansi ya IEC, ndipo kulolerana kwamakina agalimoto kumakwaniritsa miyezo yapadziko lonse ya ISO.
Kodi pali kusiyana kotani pakati pa injini ndi mota?
Galimoto imaphatikizapo injini ndi jenereta.Ndi floorboard ya jenereta ndi mota, ziwirizo ndizosiyana.Galimoto ndi imodzi mwa njira zoyendetsera galimoto, koma galimotoyo imagwira ntchito mumagetsi, ndiko kuti, imasintha mphamvu yamagetsi kukhala mphamvu zina;Njira ina yogwiritsira ntchito injini ndi jenereta.Panthawiyi, imagwira ntchito yopangira mphamvu ndikusintha mitundu ina ya mphamvu kukhala mphamvu yamagetsi.Komabe, ma motors ena, monga ma synchronous motors, amagwiritsidwa ntchito ngati ma jenereta, koma amathanso kugwiritsidwa ntchito ngati ma motors.Ma Asynchronous motors amagwiritsidwa ntchito kwambiri pama motors, koma amathanso kugwiritsidwa ntchito ngati ma jenereta powonjezera zida zosavuta zotumphukira.
