what is the advantage of DC Motor over AC motor & Where its applicable ?..

Answer / vikas pratap singh

The brushed DC motor generates torque directly from DC power supplied to the motor by using internal commutation, stationary permanent magnets, and rotating electrical magnets. Advantages of a brushed DC motor include low initial cost, high reliability, and simple control of motor speed. Disadvantages are high maintenance and low life-span for high intensity uses. Maintenance involves regularly replacing the brushes and springs which carry the electric current, as well as cleaning or replacing the commutator. These components are necessary for transferring electrical power from outside the motor to the spinning wire windings of the rotor inside the motor.

what is the advantage of DC Motor over AC motor & Where its applicable ?..

Answer / phanendra babu

it is completely depends on the application i.e where we are
using the motor.if we require high starting torque dc series
motor is applicable or we require better speed vs current
chars. dc shunt motor is suitable,like wise depending upon
the application it will change. and the main advantage of dc
motor over ac is speed controlling ig very very easy
compared to ac motors.
