Mune zvemazuva ano maindasitiri ekushandisa,motakumhanya kudzora kwakakosha, kunyanya kumidziyo kana masisitimu emidziyo inofambiswa nemamotor akawanda. Chimwe chezvishandiso zvinonyanya kushanda zvekuwana chaiyo mota control is frequency converter. Midziyo iyi inoita basa rakakosha mukuwedzera kushanda kwemota uye hupenyu hurefu, kunyanya mumashandisirwo anosanganisira mafeni nemapombi emvura.
Frequency converters, inozivikanwawo sesiyana frequency drives(VFD), gadzirisa kumhanya kwemota nekuchinja frequency uye voltage inopihwa kumota. Ichi chimiro chakakosha pakugadzirisa kuita uye kushandiswa kwesimba. Simba rekuchengetedza simba rekushandura frequency rinonyanya kuoneka mukushanda kwemafeni nemapombi emvura, izvo zvinogona kuderedza kushandiswa kwesimba kusvika ku40%. Nekuenzanisa kumhanya kwemota kune izvo chaizvo zvinodikanwa zvesisitimu, ma frequency converter anoderedza zvisina basa simba rekushandisa.
Imwe mukana wakakosha we frequency converters kugona kupfava-kutanga mota. Nzira dzechinyakare dzekutanga mota dzinogona kukonzera yakakwira inrush currents, iyo inogona kusimbisa mota uye zvinosanganisirwa zvikamu. Mukupesana, ma frequency converters anogona kuwedzera kukurumidza zvishoma nezvishoma, izvo zvisingangodzikisi kupfeka pamabhandi ekutyaira uye mabhengi, asi zvakare inowedzera hupenyu hwese hwesevhisi yemidziyo.
Uye zvakare, iyo frequency converter inogona nyore kutanga feni pane yakaderera frequency uye nekumhanya, iyo inonyanya kubatsira kune maapplication anoda kunyatso kudzora kuyerera kwemhepo kana kufamba kwemvura. Ichi chimiro hachingonatsiridza kushanda zvakanaka chete asiwo chinobatsira kuderedza kushandiswa kwesimba zvakanyanya.
Frequency converters chikamu chakakosha chemota yemagetsikutonga uye kuve nezvakanakira zvakakosha maererano nekuchengetedza simba, hupenyu hwemidziyo uye kushanda zvakanaka. Basa ravo mune zvemazuva ano maindasitiri masisitimu haagone kurerutswa uye iwo chinhu chakakosha mukutsvaga kufambisa uye kushanda kwakanaka kwemota.
