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.
No. An AC Motor is typically of the induction type. This requires a rotating magnetic field which is characteristic of AC.
DC Motor works on DC source and AC motor works on AC source
that is the point of being universal
It depends on the motor. The fan is driven by an electric motor, and it can use a dc motor (as in a car) or an ac motor (as in a house). They are not interchangeable.
For some equipment it doesn't matter, other types of equipment will be destroyed. For a simple electric heater or an incandescent bulb AC or DC are acceptable, provided the rms voltage of the AC is equal to the DC voltage. If the heater has a time switch, DC is unacceptable. A DC motor may or may not work with AC depending on its type and size. The commutator motor as used in vacuum cleaners is essentially a DC motor, but most types of AC motor are not interchangeable to DC. Electronic circuits usually required a DC supply and if AC is applied many of the components will be destroyed.
motor will not rotate
A dc series motor can work on dc and ac because dc motors are totally reversible.
No it cant
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.
To state it simply, a DC brushless motor is not a DC motor. It is an AC motor with an inverter (or electronic commutator) on the front end to make the AC, so you can use a DC input.
A variable speed module in a motor can work with ac or dc source
DC Motor works on DC source and AC motor works on AC source
it will not work.
that is the point of being universal
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
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.
Ac motor have slip ring, to remove the slip ring,connected to the commutator its a dc motor.
