Ọ bụrụ ee, biko lelee ozi dị n'okpuru.
N'ime usoro ịnya ụgbọ ala na-agbanwe agbanwe, a na-ebelata moto ahụ wee kwụsị site na iji nwayọọ nwayọọ belata ugboro. N'oge mbelata ugboro ugboro, ọsọ mmekọrịta nke moto na-ebelata, mana n'ihi inertia igwe, ọsọ rotor moto na-agbanwe agbanwe. Ebe ọ bụ na ike nke sekit DC enweghị ike inyeghachi azụ azụ na grid site na akwa rectifier, ọ nwere ike ịdabere naanị na ntụgharị ugboro ugboro (ihe ntụgharị ugboro na-etinye akụkụ nke ike ahụ site na capacitor nke ya). Ọ bụ ezie na ihe ndị ọzọ na-eri ike, capacitor ka na-enweta mkpokọta ụgwọ obere oge, na-ekepụta "voltaji na-ebuli elu" nke na-abawanye voltaji DC. Oke ọkụ DC nwere ike imebi akụkụ dị iche iche.
Ya mere, mgbe ibu dị na steeti braking generator, a ga-emerịrị ihe ndị dị mkpa iji jikwaa ume ọhụrụ a. The crane resistor na sekit na-emekarị na-arụ ọrụ nke voltaji nkesa na ugbu shunt. Maka akara, ma AC na DC mgbama nwere ike ịgafe na resistors.
Enwere ụzọ abụọ ị ga-esi na-emeso ume ọhụrụ:
1.Energy oriri breeki ọrụ ike oriri breeki bụ ịgbakwunye ihapu resistors akụrụngwa n'akụkụ DC nke agbanwe ugboro mbanye na-ekposa ọkụ eletrik emegharịrị n'ime ike resistor maka braking. Nke a bụ usoro a na-emeso ike na-emegharị ahụ ozugbo, ebe ọ na-eri ike na-emegharị ahụ ma na-atụgharị ya na ike ọkụ site na sekit braking raara onwe ya nye. Ya mere, a na-akpọkwa ya "braking na-eguzogide", nke nwere ihe mgbochi na aresistor breeki.Braking unit Ọrụ nke braking unit bụ ịgbanwuo ike oriri circuit mgbe DC circuit voltaji Ud gafere kpọmkwem ókè, nke mere na DC circuit na-ahapụ ike n'ụdị okpomọkụ site braking resistor. A na-akpọ onye na-eguzogide ihe na-eguzogide mgbe niile, a na-akpọkwa resistor nke nwere nguzogide mgbanwe a na-akpọ potentiometer ma ọ bụ variable resistor ma ọ bụ Rheostat.
2.Braking nkeji nwere ike kewaa n'ime na-arụ ọrụ na n'èzí ụdị. Nke mbụ dabara adaba maka draịva ọhaneze na-agbanwe agbanwe na-adị ala, nke ikpeazụ dabara adaba maka draịva na-agbanwe ike dị elu ma ọ bụ chọrọ braking pụrụ iche. Na ụkpụrụ, ọ dịghị ihe dị iche n'etiti abụọ. A na-eji ha abụọ dị ka "mgbanwe" iji jikọọ resistors braking, ma mejupụtara transistor ọkụ, nlele voltaji na sekit ntụnyere na sekit mbanye.

Ụdị ndị a na-ejikarị eme ihe na injinịa gụnyere ripple resistors na aluminum (Al) alloy resistors.
