  • Get your motor running: Brushed DC motor driver selection

    • 3 Comments
    In my last blog I discussed how to select a stepper motor driver and in today’s post, I want to continue the series by discussing how t o select a brushed DC motor driver. Integrated brushed DC drivers are much simpler than stepper or brushless...
  • Have you considered using back-emf observers for sensorless speed estimation?

    • 1 Comments
    Sensorless control is gaining in popularity for motor drive applications which don’t demand precise control, below 10% rated speed. A fan or pump drives that operate within 20% to 100% speed range are the right candidates for sensorless control...
  • Tips for driving solenoids

    • 0 Comments
    On the surface, you might think driving a solenoid or valve actuator seams quite simple. And to be honest, in most cases it is. It’s not too terribly difficult to turn current on or off. But, what if your application requires very fast turn on ...
