Answer / rvg

These are the effets produced when a DC motor connected
with AC supply:

1.Rotor speed will be less than the rated speed.
2. Rotor produced less torque and max. will be very less.
3.Core and copper loss will be more.
4.high sparking at brush, there by reduced life.
5.Motor gets heated up easily.

Answer / rajesh tokalapudi

when a dc motor is connected to a ac supply it will run
with reduced efficiency.in case of ac reactance will comes
into picture.so,increased losses due to inductance.and
there is sparking at brushes.motor will run with reduced
speed.

Answer / infodoss

DC series motor can rotate but less speed compare to DC
supply

Answer / anand

actually motor will be damage for giving ac supply...speed
of the motor decreasing, sparking at brushes,then get
heats...in case dc series motor wil run without less
problem ....bcoz series motor os a univresal motor.....

Answer / n nagaraju

HEAT GENERATING IN THE MOTOR THEN MOTOR SHOULD BE DAMAGED

Answer / shrikanth

Motor runs with a speed less than its rated speed, sparking in brshes.

Answer / pavan

Rotor speed will be decreased.
It produces a less torque.
Losses will be more

Answer / r.s. kushwah

motor will produce less torque, spark on commutator,

Answer / ramesh maurya

motorwiil run on reduced speed

Answer / parikh snkp

it will work...coz in the nextcycle both field and armature winding both will be in reversed direction so by this we can get same side rotation ........i mean to say unidirectional rotational
