how we can differentiate a motor and a generator just by a
glance?
Answer Posted / iamdon
Not in all cases but we can surely say in some cases.
Generators are always handled by persons having experience
in the field of electrical machines.It is generally
established at dust free places.So it MAY BE SEMI OPENED
like structure.(Remember the generators hired for Indian
marriage ceremony.You can able to see the rotating parts).
Motors are handled by persons from all walks of life and
established without concerning the dust level in the
vicinity. For running a motor,one need not require a
knowledge of electrical machines.Have you ever faced a
situation when motor seller asked you: Do you know about
electrical machines? before selling you a motor.
So motor construction is ALWAYS FULLY CLOSED to ensure
safety and proper protection aganist dust during its rugged
operation.
We can distinguish between motor and generator on the
possibilities of ALWAYS FULLY CLOSED and MAY SEMI CLOSED
appearance respectively provided motor is not opened for
repair purposes and generated is not newely purchased.
