why we use dc motor instead of ac motor?

Answer Posted / john davidson

With the advancement of AC drive technology AC motors can
do just about anything a DC motor can do. They can develop
full torque at zero RPM, once the holy grail of DC,have a
wider speed range, and amost zero maintenance requirments.
And to top all that from an intial cost stand point AC
motor/drive combinations are much cheaper. As for
industrail application, in the vast majority AC is the
prefered mehtod.
