I-Slewing drives ingasetyenziswa kuso nasiphi na isicelo esifuna ngokupheleleyo-ujikelezo lwesangqa ngelixa ifuna izantya eziguquguqukayo. Zisesona sisombululo sosetyenziso olufuna{2}}ugqithiso lwamandla etorque ephezulu,{3}}ugqithiso lwentshukumo oluchanekileyo, okanye ulwakhiwo oluhlangeneyo, oluhlanganisiweyo.
Usetyenziso oluqhelekileyo luquka{0}}ujikelezo lwesangqa kubunjineli kunye noomatshini bokwakha, kunye nakwiplanti zamandla elanga nawomoya kunye{1}}noomatshini bomkhondo abazenzekelayo ubude bexesha elide. Ngenxa yobume babo obubambeneyo kunye nololiwe omfutshane wokuqhuba, iidrive ezibulalayo zifikelela ngokulula kokuchaneka okuphezulu kwaye ziququzelele ulawulo lwedijithali, zizenze zidume kwiirobhothi zeshishini.
