Chifukwa chiyani ma mota wamba sangagwiritsidwe ntchito ngati ma frequency motere?

Wambagalimoto yamagetsis nthawi zambiri amapangidwira kuti azingogwiritsa ntchito pafupipafupi komanso nthawi zonse, koma amakumana ndi zolepheretsa zikafika pakugwira ntchito mosiyanasiyana. Kulephera kusintha kusintha kwa ma frequency ndi ma voltages ndicho chifukwa chachikulu chomwe sichingagwiritsidwe ntchito moyenera ngatima frequency motor motors.

Imodzi mwazovuta zazikulu ndi ma motors ochiritsira ndi mapangidwe awo, omwe amakonzedwa kuti azigwiritsidwa ntchito pafupipafupi, nthawi zambiri mphamvu yamagetsi ya 50 kapena 60 Hz. Magalimoto osinthika akagwiritsidwa ntchito kuwongolera kuthamanga kwa ma motors awa, zoyambira za injiniyo zimakhala zosagwirizana ndi zomwe zimafunikira pakuthamanga kosinthika. Ma frequency a frequency drive amasintha ma frequency olowera ndi ma voliyumu, zomwe zingayambitse zovuta zamagalimoto ndi ma mota wamba.

Komanso, zotsatira zaVFD injinipa injini zingakhalenso zowononga. Mwachitsanzo, mphamvu yotchinjiriza ya ma windings a mota sangakhale okwanira kuthana ndi ma spikes amagetsi ndi kusiyanasiyana koyambitsidwa ndi VFD. Izi zingapangitse kuti kutchinjiriza kulephereke msanga, zomwe zimapangitsa kukonzanso kokwera mtengo kapena kusinthidwa.

Pa liwiro lotsika, kuziziritsa ndi nkhani ina yofunika kwambiri. Ma motor wamba amadalira mpweya wina wopangidwa ndi mapangidwe awo kuti athetse kutentha. Mukathamanga pa liwiro lotsika, kuzizira kumachepetsedwa, zomwe zimayambitsa kutentha kwambiri komanso kuwonongeka komwe kungatheke. Izi zimakhala zovuta makamaka pamapulogalamu omwe amafunikira kuthamanga pang'onopang'ono kwa nthawi yayitali, chifukwa injiniyo imatha kulephera kusunga kutentha koyenera.

Zolepheretsa kapangidwe kake ka ma mota wamba, kuphatikizidwa ndi zovuta za ma inverters pa kutchinjiriza ndi kuzizira, zimawapangitsa kukhala osayenera kugwiritsa ntchito pafupipafupi. Kuti muzitha kuyendetsa bwino liwiro komanso magwiridwe antchito odalirika, ma mota odzipatulira odzipatulira ndi ofunikira chifukwa adapangidwa kuti akwaniritse zosowa zama frequency osinthika.
