Mu myaka yashize, gupakira ibintu byo mu kirere byakoreshejwe cyane mu nganda zitandukanye, nka elegitoroniki, amavuta yo kwisiga, n'ibiribwa. Nka kimwe mu bintu byingenzi bipfunyika mu kirere, imashini isunika ikirere isaba umuyaga mwinshi wo mu kirere kugira ngo utange umwuka uhoraho kugira ngo ushire umusego. Ni muri urwo rwego, icyuma kitagira amashanyarazi cya DC cyahindutse igisubizo cyiza ku mashini zogosha ikirere, bitewe n’imikorere yacyo yo hejuru no gukoresha ingufu nke.

Brushless DC blower ni ubwoko bwambere bwa blower ikoresha rotor ya magnet ihoraho hamwe nubugenzuzi bwa elegitoronike kugirango bitange umwuka. Ugereranije na moteri gakondo, ifite ibyiza byinshi, nko gukora neza, urusaku ruto, no kuramba. Mubyongeyeho, amashanyarazi ya DC adafite amashanyarazi arashobora kugenzurwa byoroshye na microcontroller, bigatuma ikwiranye nurwego runini rwa porogaramu.

Mu mashini yo guhumeka ikirere, icyuma cya DC kitagira amashanyarazi gifite uruhare runini mugutanga umwuka wizewe kandi uhoraho kugirango uzamure umusego. Nuburyo bukora neza hamwe n urusaku ruke, icyuma cya DC kidafite amashanyarazi gishobora kuzamura umusaruro no kugabanya umwanda w’urusaku aho ukorera. Byongeye kandi, amashanyarazi ya DC adafite amashanyarazi afite ubunini buke nuburemere bworoshye, bigatuma byoroshye gushiraho no kubungabunga.

Mu gusoza, ikoreshwa rya DC zitagira amashanyarazi mu mashini zo mu kirere ni inzira nziza mu nganda zipakira. Nkibice byingenzi bipfunyika mu kirere, imashini zogeza ikirere hamwe na DC zitagira amashanyarazi zirashobora gutanga ibisubizo byujuje ubuziranenge kandi byangiza ibidukikije kubicuruzwa bitandukanye. Hamwe niterambere ryihuse rya tekinoroji ya DC idafite amashanyarazi, twizera ko imashini zogeza ikirere hamwe na DC zitagira amashanyarazi zizamenyekana kandi zizakoreshwa cyane mugihe kizaza.
