Answer / thuranga

we can guarantily distinguish between AC and DC motors from
distance....
I don't know why such unique answers are coming..

For AC motors a capacitor will be connected externally and
for a dc motor it will not be connected.

Answer / vishvesh

Guys,
We can just judge the DC and AC Motors by looking on the
surface of the motor body ,if you find any capacitor on or
beside the body, then it is AC motor,if the motor is single
phase,

But, in three phase you can know by checking its three
phase connections at the terminal box there are three or
four wires in AC motor, while DC motor have two wires.

DC MOTOR: The pole shoes are mounted by bolts, the bolts
will be projected in the yoke. In a distance we can easily
identify whether the motor is AC or DC.

AC MOTOR: But in AC Motor we can't see the bolts mounted
in yoke

Answer / r a m e s h

Differentiation between ac & dc motors
1-Ac motor has induction properties but in Dc motor has no.
2-AC motor has starts with a capacitor to leading starting
torque where DC has shunt the field & split ring
3-the outer shape is plane of dc motor or rectangular in shape
where as AC motor has built in split bar cooling.

Answer / p.silamparasan

We can identify the motor its A.C or D.C by their physical
appearance. Basically the A.C motors are shaply in round
because it has only stator winding as 4pole or 6pole. But
the motors are shaply in rectangle because it has poles as
well as interpoles to compensate the flux leakages. So we
can find out a motor it is A.C or D.C by their physical
appearance.
Anybody kindly give me a feedback about my
answere.
