Please tell advantages disadvantages of both?
In the past, DC motors were used in heavy duty operations that required precise motion control over a range of speeds. Examples are Diesel Locomotives, motors for Aerial Gondolas at ski lifts and building elevators. AC motors are better suited to constant speed continuos operation applications. However digital control enables small dc motors to have very precise speed control via feedback. And newer AC motors have better torque characteristics to allow startup under load for applications that are not continuous running.
dc works well with batteries. ac can be plugged in the wall. dc is more portable (batts) ac doesnt run your batts dead. MIKE
