Motar lantarki ta DC mara gogewa (motar BLDC ko motar BL), wacce aka fi sani da motar lantarki mai canzawa ta lantarki (ECM ko motar EC) ko motar DC mai daidaitawa, injin ne mai daidaitawa wanda ke amfani da wutar lantarki ta kai tsaye (DC). Yana amfani da na'urar sarrafa madauri ta lantarki don canza kwararar DC zuwa ga na'urorin juyawa na mota waɗanda ke samar da filayen maganadisu waɗanda ke juyawa yadda ya kamata a sararin samaniya kuma wanda na'urar juyawa ta maganadisu ta dindindin ke bi. Mai sarrafawa yana daidaita lokaci da girman bugun wutar DC don sarrafa gudu da karfin juyi na motar. Wannan tsarin sarrafawa madadin na'urar sauyawa ta injiniya (goga) ne da ake amfani da su a cikin motocin lantarki da yawa na gargajiya.

Gina tsarin injin da ba shi da gogewa yawanci yana kama da injin maganadisu na dindindin (PMSM), amma kuma yana iya zama injin da ke juyawa da rashin son amsawa, ko injin induction (asynchronous). Hakanan suna iya amfani da maganadisu na neodymium kuma su zama masu wucewa (stator ɗin yana kewaye da rotor), inruners (rotor ɗin yana kewaye da stator), ko axial (rotor da stator ɗin suna da faɗi da layi ɗaya).[1]

Fa'idodin injin mara gogewa fiye da injinan gogewa sune babban rabon ƙarfi-da-nauyi, babban gudu, sarrafa gudu nan take (rpm) da karfin juyi, babban inganci, da ƙarancin kulawa.
