DC drives are used for the precise control of the speed and torque of DC motors. Their application is broad throughout industry, although they are gradually being replaced by solutions based on AC motors or servo motors. The latest generation of drives combine classic thyristor control of the rectified voltage – which determines the motor’s rotational speed – with modern communication networks and a computer interface.

What should you look out for when choosing a DC drive?
Selecting the right DC drive is crucial for its subsequent correct operation. Therefore, the purchasing decision requires not only analyses of technical parameters such as armature voltage and current or motor excitation, and the overload capacity required for operation, but also verification of other control elements and the drive’s internal features, which may affect the safety of the installation and personnel. Here are a few of them:
- features – one must consider how the motor is to be controlled, which control functions the drive itself is to perform directly, whether it is useful to employ an internal PLC controller, and what type of speed feedback the motor has;
- Compatibility with communication networks – check whether the drive can be connected to the communication network in use.
