Both A.C and D.C. motors have similar functions. Both of them work by converting electric energy into mechanical energy. However, A.C. and D.C. motor are powered and controlled differently. A.C. motor is powered by alternating current. The stator in the electric motor has coils that supply alternating current.

The rotor rotates inside the electric motor coil to produce torque by the rotating magnetic field. A.C. motors require any equipment to start. D.C. motor is powered from direct current. Example of a powered source is batteries. The motor is usually externally controlled. The motors are self-starting.

DC and AC motors are somewhat the same in the sense that they both use electrical energy into mechanical energy. The way that they are constructed is both different from each other. They can also be controlled in different ways.

Some people prefer the AC motor because they know that this will have the ability to last longer plus they are also known to be very rugged. There is a big possibility that their life expectancy will be much higher as compared to the DC motors. It will still depend on you which one you think will be the better option based on what you are searching for.
