DC Motor Controllers

Despite being one of the oldest electrical motor designs, DC motors are still relevant and regularly used in modern industry. Their controllability is behind their longevity – even the simplest machine can transform a DC current into mechanical rotation.

The continuation of the DC motor has led to the production of DC motor controllers, which are often simple in design but provide excellent performance. If you’re searching for a programmable motor controller for your application or project, you’ll find what you need here at RS.

Read on to find out more about DC motor controllers and their uses.

What are DC motor controllers?

DC motor controllers are devices that can manipulate the position, speed or torque of a DC-powered motor. There are a number of controllers available from brushed and brushless to universal, all of which allow the operator to set the desired motor behavior through their mechanisms.

The torque curve of a DC motor is inversely linear, meaning their torque proportionally decreases as the motor RPMs increase. This makes them easy to control with a programmable motor controller, as lowering their speed will increase their torque, and vice versa.

What are DC motor controllers used for?

Thanks to the functionality of DC motor controllers, they’re ideal for a number of applications. Often seen in solar panels or batteries thanks to their excellent ability to start torque high and drive high inertia loads, their speed is much easier to control when comparing them to AC motors.

If you want to reverse the motion of your application or project, you’ll find DC motors and programmable motor controllers a much better fit. Unlike AC motors, you can start and stop DC motors rapidly and with ease.
