You can change DC to AC with a voltage inverter; sold at radio shack, or other electronic stores. Most dc motors are generally low voltage. The only inverters that I know of change 12 volts dc to 120v ac which is common to run house hold appliances off your car battery. You could then take the 120v ac and plug in a step down transformer to the voltage required by the motor. Hope this helps.
Common DC motors will not work on AC. This is because they contain permanent field magnets and are reversible by reversing the polarity of the applied current. Since AC reverses 60 times per second, the motor will try to follow the reversals, but will end up not turning at all, or perhaps buzzing a little bit. Also, it will overheat quickly in this state. It is easy to change an AC power source to DC by inserting a diode or rectifier in series with the motor and AC source, but the AC voltage must match the DC voltage rating of the motor fairly closely. A transformer may be needed ahead of the rectifier to reduce the voltage if house current is to be used. The diode used must be rated to handle the maximum voltage and peak current expected. (This will depend on the motor load.) Also, the motor brushes may develop high voltage spikes that can damage the rectifier, so it is a good idea to add a capacitor across the motor to absorb these. There is a type of motor called a universal motor or an AC/DC motor that will run on AC or DC (usually the DC voltage required is lower than the AC required). These motors have no permanent magnets, using instead an electromagnetic field coil. The reason these work on AC is because the field coil polarity reverses along with the armature coil when the AC source reverses, keeping the attraction between the two coils in the same direction. Most portable power tools and vacuum cleaners contain these motors, although they aren't intended to ever run on DC. They are popular for tool applications because universal motors also happen to be very powerful for their size and weight. A typical 115 volt universal motor will run just as well on about 30 volts DC.

∙ 10y agoThat depends on the construction of the motor. There are some "DC" motors that are actually AC/DC motors and will work the same on either type of supply, these motors use commutators and have windings on both the rotor and stator excited by the same supply. Other DC motors will not operate at all on AC but will just vibrate uselessly, these motors use permanent magnet stators. Advanced types of DC motors such as the brushless DC motor cannot even be fed AC power as they are actually driven by special control electronic circuits powered by DC and are not connected directly to any supply.

Comment:
Not all common DC motors has permanent field magnets. A series motor can run on either AC or DC. Its rotor and stator must be laminated however to reduce the effects of eddy currents.

Can AC motor work on DC?
use a inverter to change dc to ac or couple it to a ac motor making it a motor generator. Comment: AC motors cannot run on DC since their principle of operation based on induction. There's an exception,however, and thats for Universal Series motor which can run on either AC or DC.
Can compressor run in DC volt?
There are compressors with motors designed to run on DC. A compressor with an AC motor can't.
Why dc series motors cannot be used in home?
DC series motors run on DC power. Homes have AC power, not DC power. You could use DC motors in homes if you have a power supply or use a battery, but it is usually more cost effective to use an AC motor.
What AC motor is used in an escalator?
we can either use dc series motor or induction machine ,but dc supply is not easily available so we use induction motor ,
What is type of DC and ac motors?
DC Motor :- SHUNT MOTOR, Series Motor, Compund Motor, ( mainly used in traction system only. as there performanace is very poor & DC supply is not available easily so there uses is less then AC motors,) AC Motor:- Induction Motor ( Slip ring Type, squrrile cage Induction motor) Syncronous Motor.
What is the advantages of the universal motors?
the universel motor can runs at both ac and dc supply.
When ac motor is connected with DC supply?
Basically AC motors would not work on DC supply but there's however an exception for a Universal motor also known as a series motor. This is the only motor as far as I know that work on both AC and DC.
Can a DC series motor with speed control be connected on AC supply?
A dc series motor with speed control can be connected on ac supply because dc machines are totally reversible.
What is dc motor with synchoronous operation?
A synchronous motor is an ac motor that does not run on dc.
What motor works on both ac and dc supply?
dc series moter
Can you convert a DC motor to run on AC?
The easiest way would be to convert the AC power to DC by using a rectifier diode and a filter capacitor. In that way you can now run your DC motor on DC.
Can motor run on ac or dc?
Motors are available that run on either.
What happens when an ac motor is given dc supply?
it burns thats it
What will happen if you will give ac supply to dc shunt motor?
it will not work.
What happens if a DC motor is connected to an AC supply?
Through loda

How do you differentiat dc motior and ac motor physicaly?
if you power an ac motor with dc or a dc motor with ac you will likely start smelling smoke and the motor will be damaged. If the motor is marked "3-phase", "shaded pole", or "induction" it is an ac motor! BTW, there are ac/dc motors that will run on both, they are wound very much like dc motors but a bit differently.
