Answer / suresh

motor has a stator and rotor.
if the rotor speed is above the synchronous speed it act as
a generator

Answer / dilip

if it is induction motor, then its rotor speed should be
greater that the RMF's Speed=Ns.
it should be noted that it will draw reactive component of
power for exciting it self.

Answer / vijayakrishna

motor has a stator and rotor.
if the rotor speed is above the synchronous speed it act as
a generator
if it is dc moor, then if you change the supply then it act
as generator

Answer / khushalchand

Only a Double excited Electrical machine can act as a
Generator. Please note eg. you cannot generate power from a
squirel cage induction motor as it does not have a dual
power source, it can only operate as a motor as the rotor
is short ckted. In all other cases where the stator
(winding) and rotors(armature) are powered seperately, only
then energy can be converted from mechanical to electrical
(generator) or electrical to mechanical (Motor)

Answer / taufic

If we are using DC motor. We can DC motor act as Dg set
with combine primemover.

Answer / p.senthil kumar

motor acts like generator for a short period of time when
it was stopped by removing input supply;this is called
regeneration. This regeneration EMF can be used for motor
braking systems in industries.

Answer / manimaran

yes. it will act on generator.
