up to what extwnt of voltage the celing fan works?

Answer Posted / manan bhatt

voltage should not be less than rated voltage ever for any
motor.
if for a few time over voltage of 10% tolerance is there it is
okay bcoz motor winding is capable to handle / sustain 155%
overload (or 255% full load) for few seconds

but for a safe operation rated voltage must be given.
