Kodi pali kusiyana pakati pa mota ndi mota yamagetsi?

Pali kusiyana kwakukulu pakati pa mota ndi mota yamagetsi. Lero tiwona kusiyana pakati pa ziwirizi ndikusiyanitsa kusiyana pakati pa izo.

 

Kodi mota yamagetsi ndi chiyani?

Mota yamagetsi ndi chipangizo chamagetsi chomwe chimasintha kapena kutumiza mphamvu zamagetsi motsatira malamulo a kulowetsa mphamvu zamagetsi.

Mota imayimiridwa ndi chilembo M mu dera (D mu muyezo wakale) ndipo ntchito yake yayikulu ndikupanga mphamvu yoyendetsera ngati gwero lamagetsi la zida zamagetsi kapena makina osiyanasiyana, pomwe jenereta imayimiridwa ndi chilembo G mu dera ndipo ntchito yake yayikulu ndikusintha mphamvu zamagetsi kukhala mphamvu yamakina.

一Kugawa magalimoto ndi magulu

1. Malinga ndi mtundu wa magetsi ogwirira ntchito: akhoza kugawidwa m'magulu awiri:Mota ya DCndi mota ya AC.

 

2. Malinga ndi kapangidwe ndi mfundo yogwirira ntchito, ikhoza kugawidwa m'maguluMota ya DC, mota yopanda ulusi ndi mota yogwirizana.

 

3. Malinga ndi momwe zimakhalira poyambira ndi poyambira: mota yoyambira ya gawo limodzi yopanda unyolo, mota yoyendetsa ya gawo limodzi yopanda unyolo, mota yoyambira ya gawo limodzi yopanda unyolo ndi mota yogawanitsa ya gawo limodzi yopanda unyolo.

 

4. Malinga ndi cholinga chake, mota ikhoza kugawidwa m'magulu awiri: mota yoyendetsera ndi mota yowongolera.

 

5. Malinga ndi kapangidwe ka rotor: mota yolowetsamo chidebe (yodziwika bwino yotchedwa squirrel cage induction motor) ndi mota yolowetsamo chidebe (yodziwika bwino yotchedwa wound asynchronous motor).

 
6. Malinga ndi liwiro la ntchito, zitha kugawidwa m'magulu awa: ma mota othamanga kwambiri, ma mota othamanga pang'ono, ma mota othamanga nthawi zonse ndi ma mota olamulidwa ndi liwiro. Ma mota othamanga pang'ono amagawidwa m'ma mota a giya, ma mota ochepetsa ma electromagnetic, ma mota a torque ndi ma mota ogwirizana ndi claw-pole.
 

二Kodi mota yamagetsi ndi chiyani?

 

Mota yamagetsi (Mota) ndi chipangizo chomwe chimasintha mphamvu zamagetsi kukhala mphamvu yamakina. Ndi kugwiritsa ntchito ma coil opatsidwa mphamvu (omwe amadziwikanso kuti stator windings) kuti apange mphamvu yamagetsi yozungulira ndikugwira ntchito pa rotor (monga chimango chotsekedwa cha aluminiyamu) kuti apange torque yozungulira yamagetsi yamagetsi. Ma mota amagetsi amagawidwa m'magulu awiri:Ma mota a DCndi ma mota a AC malinga ndi gwero lamagetsi lomwe limagwiritsidwa ntchito. Ma mota ambiri amagetsi m'makina amagetsi ndi ma mota a AC, omwe amatha kukhala ogwirizana kapena osagwirizana (liwiro la mphamvu ya maginito ya stator ya mota ndi liwiro lozungulira la rotor sizimasunga liwiro logwirizana). Mota yamagetsi imakhala ndi stator ndi rotor. Njira yoyendetsera waya wopatsidwa mphamvu mu mphamvu ya maginito imakhudzana ndi njira ya mphamvu yamagetsi ndi njira ya mizere yolowera yamagetsi (njira ya mphamvu yamagetsi). Mfundo yogwirira ntchito ya mota ndi yakuti mphamvu yamagetsi imagwira ntchito ngati mphamvu pa mphamvu yamagetsi, zomwe zimapangitsa kuti mota izungulire.

 

三、Kapangidwe koyambira ka mota yamagetsi

 

1. Kapangidwe ka mota ya magawo atatu yopanda mphamvu imakhala ndi stator, rotor ndi zina zowonjezera.

 

2. Mota ya DC ili ndi kapangidwe ka octagonal, kokhala ndi laminated mokwanira ndi series excitation winding, komwe ndikoyenera kugwiritsa ntchito ukadaulo wowongolera wokha pomwe kufunikira kutembenuka kutsogolo ndi kumbuyo. Zitha kupangidwanso ndi series-excited windings malinga ndi zosowa za makasitomala. Ma mota okhala ndi kutalika kwapakati kwa 100 mpaka 280 mm alibe compensation winding, koma ma mota okhala ndi kutalika kwapakati kwa 250 mm ndi 280 mm amatha kupangidwa ndi compensation winding malinga ndi zikhalidwe ndi zosowa zinazake, ndipo ma mota okhala ndi kutalika kwapakati kwa 315 mpaka 450 mm ali ndi compensation winding. Miyeso ndi zofunikira zaukadaulo za ma mota okhala ndi pakati kwa 500-710mm zikugwirizana ndi miyezo yapadziko lonse ya IEC, ndipo ma mechanical dimensional tolerances a ma mota akugwirizana ndi miyezo yapadziko lonse ya ISO.

 

 

Kodi pali kusiyana kulikonse pakati pa mota ndi mota yamagetsi?

 

Ma mota amagetsi amaphatikizapo ma mota ndi ma jenereta. Ndi mawu wamba a ma jenereta ndi ma mota, ndipo awiriwa amasiyanitsidwa ndi kusiyana kwake. Mota yamagetsi ndi imodzi mwa njira zogwirira ntchito za mota, koma imagwira ntchito mumagetsi, zomwe zikutanthauza kuti mphamvu zamagetsi zimasinthidwa kukhala mitundu ina ya mphamvu; njira ina yogwirira ntchito ya mota ndi jenereta, yomwe imagwira ntchito munjira yopanga mphamvu, kusintha mitundu ina ya mphamvu kukhala mphamvu zamagetsi. Komabe, ma mota ena monga ma mota ogwirizana nthawi zambiri amagwiritsidwa ntchito ngati ma jenereta, komanso angagwiritsidwe ntchito mwachindunji ngati ma mota amagetsi. Ma mota osagwirizana nthawi zambiri amagwiritsidwa ntchito ngati ma mota amagetsi, koma, powonjezera zigawo zosavuta zamkati, angagwiritsidwenso ntchito ngati ma jenereta.
