Can motor act as generator (OR) vice versa? explain how
does it do please post the answer technically

Answer Posted / moody

of course
for induction motor as example if its mechanical speed
exceeded its synchro speed so the power will be given to

and this region on the T-NS curve is called generating
region
where slip s= ns-n/ns
