What will happen if 230V DC motor connected to 230V AC
Supply?
Answers were Sorted based on User's Feedback
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.

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
Is This Answer Correct ? | 54 Yes | 27 No |
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
Is This Answer Correct ? | 15 Yes | 7 No |
Answer / shrikanth
Motor runs with a speed less than its rated speed, sparking in brshes.
Is This Answer Correct ? | 11 Yes | 4 No |
Answer / pavan
Rotor speed will be decreased.
It produces a less torque.
Losses will be more
Is This Answer Correct ? | 10 Yes | 5 No |
Answer / r.s. kushwah
motor will produce less torque, spark on commutator,
Is This Answer Correct ? | 5 Yes | 1 No |
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

what is the difference between Resistance VS capacitance
i have one source transformer with the capacity of 50KVA, connected with two loads 10kw and second one is 15kw.. how can i calculate first load in KVA and second one in KVA .. because Kva rating, power factor rating of of transformer is different from the load… there must be some way to calculate load KVA rating and power factor….
