As already mentioned - and as can be easily guessed - the fundamental difference between a DC electric motor and an AC motor lies in the type of power supply: while AC motors are powered by alternating current, DC motors are powered by direct current which is that supplied, for example, by batteries. A further difference is the speed they are able to reach: while the speed of an AC motor is controlled by varying the current in the motor, that of a DC motor is controlled by varying the frequency, usually by means of a frequency converter. This is the reason why AC motors reach a higher speed than DC electric motors.
Electric DC motors are widely used in the industrial sector because they are precise, easy to install, even in mobile systems, have a high starting torque, and their starting, stopping, acceleration and reversing are carried out quickly.
DC electric motors are therefore particularly suitable for dynamic applications requiring high precision or in terms of speed, as in the case of lifts, or in terms of position, as in the case of machine tools or robots.
