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

For refrigerators the motor current is raised beyond its rating on both conditions when the voltage of the system is more(say 270v) than the rated voltage(220v) as well as when the voltage of system is less(say 160v) than normal voltageof 220v, why explain?
