What is a controller?

An electronic controller is needed to manipulate position, speed or torque of a brushless DC motor. It can also be used in other DC motor types. The controller is used to switch DC currents to the motor windings, producing magnetic fields that effectively adjust the phase and amplitude of the DC current pulses.

The speed/torque curve associated with a DC motor is inversely linear, which means that the torque decreases proportionally, as the RPM of the motor increases. This means that a DC motor is actually quite easy to control because reducing the speed will increase torque and vice versa.

Choosing a controller

There is a huge choice in DC controllers to suit myriad applications. This can make them tricky to specify but the Parvalux team is always on hand to help you choose the right controller for your project.

If you want to be a little more self-sufficient, we’ve come up with a few questions that might help you identify the controller best suited to your application:

  1. Do you need a dual-motor controller i.e. one controller for two separate motors?
  2. What is the rated voltage range for the motor in use?
  3. How much of the voltage range will be used?
  4. What are you trying to control? Speed, torque, direction or all three?
  5. What type of motor do you want to control?
  6. What is the motor’s continuous current consumption whilst under load? What is the continuous current the controller can supply? Is it sufficient?
  7. Does it have built-in overcurrent/thermal protection?
  8. For microprocessor drives, what control method will be used (PWM, R/C, analog voltage, etc.)? Is control software required?

There are many DC controllers available and our engineers are always happy to discuss your project.
