Kusiguquli sefrikhwensi, i-motor fast braking noma ukuma okunembile, ngokuvamile kusetshenziswa i-power braking kanye ne-regenerative braking. Ngemodi yokubopha amandla, i-torque yokubhuleka edingwa uhlelo ingaphansi kuka-20% we-torque elinganiselwe ye-motor futhi i-braking ayisheshi, asikho isidingo sokumelana ne-braking yangaphandle, futhi kuphela ukulahlekelwa okusebenzayo kwangaphakathi kwe-motor can. yenza umkhawulo kagesi oseceleni kwe-DC ube ngaphansi kwevelu yesenzo sokuvikela i-over-voltage. Ngokuphambene nalokho, kuyadingeka ukukhetha i-resistor ye-braking ukuze uchithe le ngxenye yamandla avuselelwe injini. Ukuze ubone ukubhuleka kukagesi, uhlangothi lwe-DC lwe-inverter kufanele lufakwe isekethe yokuthola i-voltage ukuze kutholwe i-voltage ye-capacitor ukuze kubonakale ukubhuleka kwamandla.Amabhuleki resistorsasetshenziswa kabanzi emikhiqizweni ehlukahlukene ye-elekthronikhi.
Lapho ubhuleka nge-resistor yangaphandle ye-braking, i-resistor yangaphandle kufanele ikwazi ukumunca u-80% wamandla kagesi aguqulwa amandla angaba namandla, okuthi ama-20% awo angadliwa nge-motor ngendlela yokukhipha ukushisa, ngalesi sikhathi inani of the resistor braking iba ezincane, kungakhathaliseki motor ngokuphindaphindiwe decelerated, ukukhethwai-braking resistoramandla alinganisiwe ahlukile. Uma ukwehla okungaphindiwe, isixhasi sokubhuleka sesikhathi esimaphakathi (T-tS) > 600s. Ngokuvamile sebenzisa i-resistor duty resistor, lapho ukubhuleka ngezikhathi ezithile, amandla avumelekile we-resistor azokwandisa ukusetshenziswa kokukhethwa okulungile kwe-braking unit resistor kunganciphisa isikhathi sokumisa samahhala semithwalo ye-inertia enkulu ukuze kuzuzwe ukuma ngokushesha noma ukuma okunembile; kungase futhi kube in the bit amandla imithwalo yehliswa ukuze kuzuzwe operation regenerative.
Amanye amakhasimende 'i-electrolysis workshop multifunctional unit design ayizange icabange ukwengeza i-inverteri-braking resistor, okuholela esikhathini eside sokuma mahhala kanye nebanga elide lokushushuluza imoto enkulu, ekhona ingozi efihliwe yokukhiqiza nokusebenza; Kunzima ukubona ukuma okunembile kwezinqola zamathuluzi nama-aluminium trolleys, okuthinta ukusebenza kahle komsebenzi. Ngemuva kokufakwa kwe-braking resistors, izinkinga ezingenhla ziyaxazululwa. Kodwa-ke, kufanele kuqashelwe ukuthi, ekukhethweni kwe-braking resistor, hhayi kuphela ukucabangela izidingo zokukhethwa komkhiqizi we-inverter braking resistor, kodwa futhi ngokuvumelana nezidingo zokulawula komsebenzisi kanye nokusetshenziswa kwezindawo ezahlukene, kufanele kube ngesivinini. , i-torque nezinye izilinganiso, bese kubala ukukhetha okulungile kwe-resistor yokubhuleka, ukuze kuzuzwe izimfuneko zokulawula zomsebenzisi.
