how we protect the motor & what are the components required
for that ?
Answer Posted / kalolia alap r
depend on the kind of current,i.e both a.c and d.c required
protection.. motor required starters,like basic D.O.L etc.
in small motor we do not required armature resistance but in
large size of motor,we required large armature
resistance..basicaly required component is resistence in
megaohms and some times induction regulator like auto
transformers....
