Can 12 Volt DC Motor Work On 12 Volt AC Supply?

  Yes, you can use a step-down transformer & a bridge rectifier to convert AC into DC and drive your motor

  saurav actually i want to ask is tat.....let us consider a dc motor having 2 terminal A & B . i connect +ve(of dc source ) to A terminal & -ve to B terminal then motor will rotate
  in clockwise & if i interchange polarity then motor will move anticlockwise ........
  now wat if i connect AC souce to a dc motor ....as half cycle ac is +ve & half cycle is -ve ...so will tat motor roatae clockwise for +ve half cycle & then rotate anti-clockwise for -ve half cycle

  i think dc motor wont work on 12v ac
  the dc value of the ac is 0.
  secondly as u said fwd n rev bias... but both the effects nullify each other as it happens very fast...
  but still we check it practically...
  u get a dc motor to clg tomorrow.

  yeah it will give you a good job of fixing over head wire from the transmission lines and stuff like that
  
  never try this out it is potentially lethal in many ways my pal
  
  the motor will only destroy itself and things around it if you try this out

  this is not possible as the number of alternating cycles in the AC main is far too much per second and so there is no chance of it to work

  dc motor never ever works with directly AC values.some conversion circuitry is required to run,that's normal conversion AC to DC, my bro... because DC is consists of "+" and "-"polarities not phase neutral polarities concepts. if you apply the ac supply to DC motor simply winding in side the motor get damages, either in both the situations of AC and DC motor with excitation of opposite field applying respectively directly motors get damages. according the motor nameplate(ratings) we need to apply the supply.
