Dc is an electrical term for direct current. Ac stands for alternating current. As you probably guessed a dc moter uses dc current and an ac moter uses ac current.
P.S. Most home outlets use ac current.
Only Stator winding is similar in both the cases.
ac machines can run only in one direction but dc machines can run in both the directions depending upon the direction of current flow into it. If we change polarity of input supply we can reverse the direction of motion of dc machineCommentThe above answer isn't altogether true, as it's very easy to change the direction of an AC machine. For example, to change the direction of rotation of a three-phase induction motor, the motor controller interchanges two of the three line conductors.The main difference used to be that the speed of DC machines is easier to control, but that is a thing of the past thanks to developments in electronic motor controllers.
AC series motor uses the electric current to run the motor. Whereas DC motor uses the battery power to run it.AnswerAn a.c. series motor is termed a 'universal motor', because it will run on either a.c. or d.c. A.C. series motors are constructed in essentially the same way.
Yes, what matters is that the cable can take the correct voltage, and is thick enough to carry the required current, but ac or dc makes no difference.
dc ammeter has three connecting pins while ac has four

induction motor is AC motor also synchronic motors are AC motors but second one has not slip but first one has slip . shut motor is DC motor
AC stands for alternating current, and DC is direct current. A motor is a device that uses electrical energy to spin. An AC motor uses AC voltage, and a DC motor uses DC voltage. http://ezinearticles.com/?The-Difference-Between-AC-and-DC-Electric-Motors&id=193767
AC power is made by alternating current and DC does not change.
There is no difference between AC AND DC chockes
DC Motor works on DC source and AC motor works on AC source
The main difference is in how the carbon brushes are used. In an AC slip ring motor, the brushes transfer power to the rotor through slip rings, whereas in a DC commutator motor, the brushes switch the current direction on the rotating armature to maintain torque and rotation. Additionally, the design and composition of the brushes may vary to accommodate the specific requirements of each motor type.
The main advantage of ac- it required less maintainance The main disadvantage of ac-it can not be stored the main advantage of dc -it required less amount of conductors to transmit and easily stored The main disadvantage of dc-it is more dangerous than ac at high voltage
The big difference is that the synchronous motor's rotor can have a variable current applied to it through its field slip rings. Both types of motors have their own advantages. With a synchronous motor in the system, the systems power factor can be regulated.

AC motor produce mechanical power and absorbed electric energy the power generator produce electrical power absorbed mechanical power
