Answer Posted / prabhu
dc machines is not prefer to use at place where flamming
gases are coming out because it requires brushes and
commutator arrangements. it causes sparking during the
operations.
so we can go for Induction motors,preferable squrrle cage
induction motor are used. there are two types of IM.there
are i]slip ring IM ii]squrrle cage IM.
in the first one slip ring IM, it also not preferable
beacuse of slip ring arrangements. it also cause sparking.
second one squrrle cage is completely safe there is no
slipring arrangements.
