What Are DC Drives?

DC drives are motor speed control devices that provide variable speed control and energy savings for DC motors. They accomplish this by supplying a specific amount of voltage to the motor, directing it to run at the desired speed. The motor then draws an electrical current from the drive based on the motor shaft’s load demand. DC drives are ideal for applications that require low speed control, power and torque.

DC drives come with their own specialized functions and benefits. They have a wide speed range, high starting torque and reliable speed regulation features, as well as a compact, lightweight design. These low-cost solutions are easy to install and control and have fast start, stop, reverse and acceleration features.

DC Drive Applications

Generally, any machine with a DC motor can be accompanied by a DC drive. Because so many appliances and devices use these motors, DC drives excel in applications across many diverse industries, including:

  • – Metalworking.
  • – Plastic.
  • – Rubber.
  • – Chemical.
  • – Material handling.
  • – Lift, crane and hoist.
  • – Manufacturing.
  • – Textiles.
  • – Printing.
  • – Packaging.
  • – Entertainment.
  • – Food processing.


What’s the Difference Between Drives and Motors?

DC drives and motors are two vital parts of the same system. While they go hand-in-hand, they are not synonymous. Motors are mechanical or electrical appliances that power machines by delivering the necessary amount of linear or rotational force.

On the other hand, drives are strictly electronic devices that regulate and control all energy that reaches the machine’s motor. These drives carry the energy to the motor in frequencies proportional to the load demand, indirectly adjusting the motor’s speed and torque.

In short, motors generate power while drives regulate and control it.

How Do DC and AC Drives Differ?

DC and AC drives have the same general purpose and functions, but they have varying strengths and are ideal for different applications. DC drives have high start-up torque and simple circuits but tend to experience more mechanical and stability problems from natural wear and tear. They are typically used in applications that require constant speed.

AC drives have running induction motors that specialize in managing rapid changes in speed. These devices are more energy-efficient than DC drives but are generally more complicated in terms of programming and installation — though recent advancements have made them simpler to use. AC drives are easy to monitor and encounter fewer mechanical issues and maintenance requirements than DC drives.
