Kuzicelo zezimboni zanamuhla,imotoukulawula isivinini kubalulekile, ikakhulukazi ezintweni zokusebenza noma izinhlelo zemishini eshayelwa amamotho amaningi. Elinye lamathuluzi asebenza kahle kakhulu ekufinyeleleni ukulawulwa kwezimoto okunembayo isiguquli semvamisa. Lawa madivaysi adlala indima ebalulekile ekwandiseni ukusebenza kahle kwezimoto nokuphila isikhathi eside, ikakhulukazi ezinhlelweni ezibandakanya abalandeli namaphampu amanzi.
Iziguquli zemvamisa, ezaziwa nangokuthiama-drive frequency drives(VFD), lungisa isivinini semoto ngokushintsha imvamisa namandla kagesi anikezwe injini. Lesi sici sibalulekile ekuthuthukiseni ukusebenza nokusetshenziswa kwamandla. Umphumela wokonga amandla we-frequency converter ubonakala ikakhulukazi ekusebenzeni kwamafeni namaphampu amanzi, okunganciphisa ukusetshenziswa kwamandla kuze kufike ku-40%. Ngokuqhathanisa isivinini semoto nezidingo zangempela zohlelo, iziguquli zemvamisa zinciphisa ukusetshenziswa kwamandla okungadingekile.
Enye inzuzo ebalulekile ye-frequency converters yikhono lokuthambisa injini. Izindlela zendabuko zokuqala zezimoto zingaholela ekungeneni okuphezulu kwemisinga, okungagcizelela injini kanye nezingxenye ezihambisanayo. Ngokuphambene, abaguquli bemvamisa bangakwazi ukwandisa kancane kancane isivinini, okungagcini nje ukunciphisa ukugqokwa kwamabhande okushayela nama-bearings, kodwa futhi kwandise impilo yonke yesevisi yemishini.
Ngaphezu kwalokho, isiguquli sefrikhwensi singakwazi ukuqala kalula ifeni ngamafrikhwensi aphansi nangesivinini, okuzuzisa kakhulu izinhlelo zokusebenza ezidinga ukulawulwa okunembile kokugeleza komoya noma ukunyakaza koketshezi. Lesi sici asigcini nje ngokuthuthukisa ukusebenza kahle kodwa futhi sisiza ukwehlisa ukusetshenziswa kwamandla ngokuqhubekayo.
Iziguquli zefrikhwensi ziyingxenye ebalulekilemotor kagesilawula futhi ube nezinzuzo ezibalulekile ngokonga amandla, impilo yezisetshenziswa nokusebenza kahle. Iqhaza labo ezinhlelweni zezimboni zesimanje azinakubukelwa phansi futhi bayingxenye ebalulekile ekuphishekeleni ukusebenza kwezimoto okusimeme nokusebenza kahle.
