DC Motors | OMDC

The OMDC Ome Motors series DC motors are DC motors, or power converters that operate in two different modes:
  • Or they convert the absorbed electrical energy into mechanical energy, when they are able to provide sufficient mechanical power to start and then drive a moving load (in which case the DC motor works just like a motor);
  • Or they convert the mechanical energy received into electrical energy when they are subjected to the action of a driving load (in which case the direct current motor works, therefore, like a generator).
The DC motor is still of great importance today, despite its increasingly frequent use and the “rivalry” with AC motors, which – as AC motors – are also among electric motors. In particular, thanks to the possibility of adjusting the speed and torque with precision and extreme variability, the DC electric motor is used in the most diverse industrial applications.

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. DC electric 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.
