Ahhh!!! That stepper driver’s high pitch squealing is driving me nuts! Well, it has to drive you somehow as after all it is a “driver”, right? Well, nuts should not be it. It should drive your stepper motor and be done…
My Chip Is Running Hot! Am I Doing Something Wrong?
OK, you are not doing anything wrong. Maybe you did something wrong a few years ago when you decided to be born in this universe as the laws of physics are pretty much defining that your chip will run hot.…
How to Select the R and C at the RCx Pins on the DRV8811 Bipolar Stepper Driver
The DRV8811 is clearly a bipolar stepper driver that makes our lives considerably easier. It is just so simple to drive a stepper with this powerful device, as well as similar internal indexer microstepping engines, who takes care of all the nuances…
Tackling the Brushless DC Motor Experience
I have been called the stepper expert at work. Although I have been developing stepper hardware and software for the last 10 years, I am hardly an expert at all. But when compared against Brushless DC Motors, or BLDC, then…
How to Get the 2.5A Out of your DRV8811 Bipolar Stepper Motor Driver
When I designed the AE-MDL-STPR1 I was naive enough to think that a two layer copper and 2″ by 2″ board should be a good platform to run the DRV8811 bipolar stepper motor driver at whatever current I could…
Taking Advantage of the DRV8811 Microstepping Driver
Driving a stepper motor has its advantages and its disadvantages. For example, there is no better way to control rotation speed and position than with a stepper. Sure, you may argue that Brushed and Brushless motors on servo systems are…
