Igwe eletriki igwe eletrik nke DC nwere ogologo akụkọ ihe mere eme, ihe karịrị 100 afọ.

Igwe ọkụ eletrik DC na-enweghị brush nwere naanị akụkọ ihe mere eme afọ 40.

moto DC a na-akpụ akpụ: moto DC brushed bụ moto na-agbagharị agbagharị na ngwaọrụ ahịhịa nke na-agbanwe ike eletrik ka ọ bụrụ ike eletriki (motor) ma ọ bụ ike eletrik n'ime ike eletrik (generator) .N'adịghị ka moto na-enweghị brushes, a na-eji ngwaọrụ brush na-ewebata ma ọ bụ na-emepụta voltaji na mmiri ọkụ. bụ ihe ndabere nke niile Motors, o nwere àgwà nke ngwa ngwa mmalite, oge braking, ezigbo ọsọ ụkpụrụ na a nnukwu nso, akara sekit dịtụ mfe na na.

moto DC na-enweghị brush: brushless DC moto bụ a ahụkarị mechatronics ngwaahịa, nke na-emi esịnede nke moto ahu na driver.Since na brushless dc moto na-arụ ọrụ na akpaka akara mode, ọ gaghị tinye ọzọ malite windings na rotor dị ka synchronous moto malitere site arọ ibu ibu. n'okpuru agbanwe ugboro ọsọ iwu, na ọ gaghị emepụta oscillation na nke nzọụkwụ mgbe ibu mgbanwe mberede.Medium na obere ikike brushless dc moto na-adịgide adịgide magnet, ugbu a na-emekarị na-eji elu magnetik ike obere ụwa ndfeb (nd-fe-b) ihe.
