Can a DC motor run on AC?
Some types can. A low-power dc motor that does not use a permanent magnet can run at reduced rating on 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.
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. 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.

the quick answer is you cant. squirrel cage induction motors need AC power to generate the magnetic field in the rotor...if however you have a motor that has brushes in it (drills, mixers,etc) then this motor can be run off ac or dc..the commutator brushes do the work of moving the current to the proper coils at the proper time.

Some AC motors are designed to start running as soon as electricity is provided. Other AC motors are designed for a specific purpose and do not start on AC current. They will RUN on AC, but require a DC current to start. Here's where the capacitor comes in. It stores DC power that, when released, starts the motor turning. At this point, AC current will nicely run the motor.
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…
