Vashanduri vemafrequency, inozivikanwawo semadhiraivha anochinja-chinja (VFDs), zvinhu zvakakosha mumabasa akasiyana-siyana emaindasitiri nemabhizimisi. Basa rayo guru nderekudzora kumhanya uye torque yemota nekushandura frequency uye voltage inopihwa kumota. Chinyorwa chino chinopa ruzivo rwakadzama rwekuti seima frequency convertersbasa, mashandisirwo azvo, uye mabhenefiti azvinopa.
Nheyo huru yemuchina unoshandura ma frequency ndeyekushandura simba remagetsi risingachinji (AC) kuita simba remagetsi rinoshanduka (variable frequency AC). Nekugadzirisa ma frequency, kumhanya kwemota kunogona kudzorwa nemazvo, izvo zvinovandudza kushanda zvakanaka uye zvinoderedza kushandiswa kwesimba. Kudzora uku kunonyanya kubatsira mumashandisirwo anosanganisira mapombi, mafeni, ma conveyors, nemimwe michina inofambiswa nemota.
Chimwe chezvakanakira zvikuru zvekushandisachinoshandura mafrequencykugona kwayo kutanga nekumisa mota zvinyoro nyoro. Nzira dzekare dzekutangisa zvakananga paindaneti dzinokonzera kukwira kwemagetsi kamwe kamwe kunomanikidza mota nemichina yakabatana.chinoshandura mafrequency, kumhanya kwemota kunowedzera kana kuderera zvishoma nezvishoma, zvichideredza kushushikana kwemuchina uye kuwedzera hupenyu hwemuchina.
Pamusoro pe,ma frequency convertersinobvumira mota kuti dzimhanye nekumhanya kwakakodzera zvichienderana nezvinodiwa nemutoro, zvichikonzera kuchengetedza simba zvakanyanya. Kana mota ichifamba nekumhanya kwakazara nguva dzese, inoshandisa simba risingakoshi, zvichikonzera mabhiri emagetsi akakwira. Nekugadzirisa frequency kuti ienderane nezvinodiwa chaizvo zvekushandisa, ma frequency converters anovimbisa kushandiswa kwesimba nemazvo uye anoderedza mari zvakanyanya.
Pamusoro pekushandisa simba zvakanaka,ma frequency convertersinobvumira kudzora kwakarurama mashandiro emota. Dzinopa mabasa akadai sekudzora torque, kugadzika nguva yekumhanyisa uye kushanda kwe multi-speed. Aya maficha anoita kuti ma frequency converters ave akakodzera maapplication anoda kumhanya kwakasiyana kwemota kana kuti anoda kukurumidza uye kudzikira kwakapfava. Maindasitiri akadai seHVAC, kurapwa kwemvura, kugadziriswa kwechikafu uye kugadzirwa kwemota anobatsirwa zvikuru nekushanda kwakasiyana-siyana kwema drive.
Imwe mukana wevashanduri vema frequency ndiko kugona kuvandudza simba remota. Simba iri rinomiririra kushanda zvakanaka kwesimba remagetsi rinoshandurwa kuita basa rinobatsira. Simba shoma rinogona kukonzera kurasikirwa nesimba zvakanyanya uye rinogona kutokonzera chirango kubva kukambani yemagetsi. Vashanduri vema frequency vanovandudza simba remagetsi nekuwedzera kushanda zvakanaka kwemota uye kuderedza kushandiswa kwesimba remagetsi, zvichizopedzisira zvaderedza mari yemagetsi.
Pamusoro pezvo, ma frequency converters anoderedza ruzha nemazinga ekuzunguzika, zvichibatsira kuti pave nenzvimbo yakanyarara uye yakasununguka yekushanda. Nzira dzechinyakare dzekudzora mota dzinoburitsa ruzha rwakanyanya panguva yekushanda, zvichikonzera kusagadzikana kwevashandi nematambudziko ehutano. Ma frequency converters anogona kudzora kumhanya kwemota zvakanaka, achideredza kusvibiswa kweruzha uye kugadzira nzvimbo yekushanda inonakidza.
Muchidimbu,ma frequency converterszvishandiso zvakakosha munzvimbo dzakasiyana-siyana dzemaindasitiri nedzekutengeserana nekuda kwekugona kwazvo kudzora kumhanya uye torque yemamota emagetsi. Nekuvandudza mashandiro emota, kuderedza kushandiswa kwesimba uye kuwedzera kushanda zvakanaka, ma frequency converters anopa mabhenefiti akawanda anosanganisira kuchengetedza simba, kuvandudzwa kwesimba, kutonga kwakaringana uye nzvimbo yekushanda yakanyarara. Kuisa mari mumhando yepamusoroma frequency converterszvinogona kuvandudza mashandiro emidziyo inofambiswa nemota zvakanyanya uye kubatsira mune ramangwana rinogara kwenguva refu.
