Joalo ka ha bohle re tseba, ho fokotsa lebelo le ho koala ha enjene ho sistimi ea taolo ea maqhubu ho bonoa ka ho fokotsa sekhahla butle. Nakong ea ho fokotseha ha maqhubu, lebelo la synchronous la motor le boetse le fokotseha, empa ka lebaka la inertia ea mochine, lebelo la rotor ea motlakase le lula le sa fetohe. Ha lebelo la synchronous le le ka tlase ho lebelo la rotor, mohato oa hona joale oa rotor o fetoha hoo e ka bang likhato tse 180, 'me motlakase o fetoha ho tloha sebakeng sa motlakase ho ea sebakeng se hlahisang. Bakeng sa ho sireletsa enjene le ho sebelisa motlakase o hlahisoang, hangata re sebelisa li-resippler tsa enjene. Li-resistors tsa ripple li sebelisa li-ripples tse otlolohileng ho thusa ho felloa ke mocheso le ho fokotsa li-parasitic inductance, hape li khetha lelakabe la retardant inorganic coatings ho sireletsa terata e hanyetsanang le botsofali le ho lelefatsa bophelo ba ts'ebeletso.
Ka liftibraking resistors, li-resistors tsa aluminium alloy li hanyetsana le boemo ba leholimo le ho sisinyeha ho feta li-resistant tse nang le masenke, hape li phahametse li-resistors tsa setso tsa porcelain skeleton. Libakeng tse thata tsa taolo ea indasteri, li-resistors tsa alloy aluminium hangata li khethoa. Ho bonolo ho palama ka thata 'me e ka kenngoa le lisinki tsa mocheso. Ho latela maemo, libaka tsa lifti le tsona li ka khetha ho sebelisa lihanyetsi tsa aluminium. Leha ho le joalo, ka kakaretso, lihlahisoa tse ngata tsa lifti li fana ka khetho ho li-resistors tsa alloy aluminium, tse ka etsang hore lifti e sireletsehe ho latela tlhokomelo ea morao-rao le ho ba le bophelo bo bolelele ba tšebeletso.
Tlas'a litlhoko tse fapaneng, lisebelisoa tsa aluminium alloy resistors le ripple resistors li sebelisoa ka lifti. Maemong a mangata, li-resistors tsa braking tsa lifti li hloka ho sebetsa ka mokhoa o tsitsitseng nako e telele. Ka hona, bahlahisi ba bangata ba lifti ba tla khetha li-resistors tsa aluminium alloy e le li-resistors tsa braking bakeng sa lifti, tse ka fokotsang palo ea litokiso, ho netefatsa polokeho ea li-elevator, le ho netefatsa ts'ebetso e ntle ea li-motor.
