    Simplifying gate driver design for brushed DC motors

    Are you looking to drive a simple brushed DC motor? Do you need to use discrete MOSFETs to drive a bunch of current through a giant brushed motor with little time for development? When you grab an off-the-shelf gate driver, you always see a diagram like Figure 1: just choose two resistors and you’re (theoretically) good to go. Figure...

    Motor start-up techniques: Part three

    I have discussed sensorless motor start-up with our InstaSPIN-FOC™ technology in part one of this series, followed by a discussion of how to generate sufficient torque at start up and maximize it while spinning your motor in part 2. In this third and final part of the series, I’ll explain how to address some challenges in applications that...

    Motor drive validation: Keeping our parts in your hands

    Have you ever seen this video with a cat wearing a miniature shark costume and riding a robotic vacuum cleaner? For the cat lovers out there this video is every bit as awesome as it sounds. If you happen to be a dog lover, not to fear! If you check out the related videos sidebar you can see videos of dogs doing the same thing. As a validation engineer...

    Under the hood of a 3-D printer – Part 1

    In a previous post, I introduced a TI Design reference design for a 3-D printer controller board shown in Figure 1 and gave a brief rundown of some of the key TI devices enabling 3-D printers. Today, I’ll provide more background about 3-D printing in general. This might be old hat to those who are well-versed in 3-D printers, but may turn on a...

    How a dual operational amplifier works in motor-drive applications

    This post is co-authored by Andrew Leverette. In my last blog post, I introduced an integrated solution for a high-current amplifier application. I talked about the advantages of TI’s ALM2402 dual-operational amplifier over a discrete solution and how it is useful to save your board space while packing critical features like over current protection...

    Motor start-up techniques: Part two

    In the first part of the series , I explained how to use ForceAngle within InstaSPIN-FOC™ to regulate motor start up. Next, I will address generating enough torque during start-up and how to maintain alignment to maximize torque. Generating enough Torque As the starting load is increased, the torque you can generate will be based on the...

    How to spin your stepper motor more efficiently – Part 2

    In part 1 of this series, I provided a few key ideas: TI hearts stepper motors. Stepper motors can be power-hungry. Back electromotive force (EMF) will indicate the stepper-motor load. You can control the output current based on back EMF. This can help save some power. No talking about current regulation! So now that all of...

    Simple BLDC motor spinning 101: Five key concerns

    The brushless direct current (BLDC) motor is the newest member of the big motor family that people just can’t stop talking about. Unlike a brushed or stepper motor, control techniques for which are very mature and standard, there have been debates on what’s the best approach to control a BLDC motor, as well as how to continue improving these...

    How to spin your stepper motor more efficiently, Part 1

    It’s no secret that we love stepper motors here at TI. We love them so much that we work to come up with integrated circuits (ICs) and development tools that make stepper motors easier and easier to drive. We have small-form-factor BoosterPacks to encourage prototyping; innovative product features like adaptive decay to eliminate motor tuning;...
