Can DC motor run on AC?

Yes. A DC series motor is capable of running when supplied with a single phase AC supply. This is because the torque, which varies as the product of the armature and field current, is always positive. Thus, a positive average torque causes the motor to rotate.

Also asked, what would happen if you tried to run a DC motor on AC power?

When A.C. supply is given to a D.C. motor: 1)In case of Series connection of armature winding and field winding , it may run. 2)But, In case of parallel connection , it won't rotate at all and will start humming and will create vibrations, as a torque produced by positive and negative cycle will cancel out each other.

Subsequently, question is, will a DC shunt motor operate on AC supply? The Shunt winding has a large number of turns so that it has appreciable inductance. When A.C is applied to a shunt motor, the large inductive reactance of shunt winding will reduce the field current too much. Consequently, Shunt motor will not usually run on A.C Supply.

Also Know, how universal motor works on both AC and DC?

The universal motor is a type of electric motor that can operate on either AC or DC power and uses an electromagnet as its stator to create its magnetic field. It is a commutated series-wound motor where the stator's field coils are connected in series with the rotor windings through a commutator.

Which is better DC or AC motor?

AC induction motors use a series of coils powered and controlled by AC input voltage. Consequently, AC motors are less efficient than DC motors. In fact, the DC motor is 30% more efficient than AC motors due to the secondary magnetic field being generated from the permanent magnets rather than copper windings.
