    Is your IGBT gate-driver power supply optimized? – Part 1

    Many of us are familiar with low-power DC motors because we see them everywhere in our daily lives. What we may not see are all the larger AC industrial motors working behind the scenes to automate the assembly of our automobiles or to lift the elevators we ride every day. These high-power motors are driven by electronics with very different requirements and with much higher current. In part 1 of this blog, we will discuss...

    How to quickly tune your stepper motor

    In our fast-paced world, there are many times we are tasked with having to make something work but don’t have time to learn the theory behind it. It’s important that it works but not as important why. This allows us to move on to the next task. In modern stepper motor drivers, tuning the motor for optimal current regulation can be one of those situations. Recently, I’ve been asked why a stepper motor...

    Get Your Motor Running: Intelligent Over-voltage Protection

    In the world of motors, drive stage damage due to over-voltage is an all too common event. Although not the only cause of over-voltage failures, supply pumping is by far the most prevalent. Supply pumping occurs when energy from the motor is returned to the supply, causing the supply voltage to temporarily increase. If the voltage increase is significant, over-voltage stressing of the drive stage occurs, either destroying...

    Start your brushless DC journey with motor startup (Part I)

    Sensor-less BLDC motors are becoming more popular. But quick, reliable start up is a challenge as many system designers have already discovered. The most difficult design challenge is the startup from zero speed since almost every sensor-less solution relies on back electromotive force (BEMF) detection to achieve the position estimation. BEMF is proportional to motor speed, which is zero before startup. As a result, you...

    The “spin” on motors in the “smart factory”

    By Karl-Heinz Steinmetz I recently discussed my belief that the world is in the fourth industrial revolution, due to the rise of “smart” factories in a blog and white paper . You might wonder as factories become smarter using sensing, haptics and the Internet of Things (IoT) how it affects motors in factories. In just a few years, intelligent sensors, motors, robots and other equipment will transform...

    What’s all the noise about sensorless BLDC motor drivers?

    Creating a drive system for three-phase brushless DC (BLDC) motors has always been a task of balancing a handful of system requirements. Care-abouts such as efficiency, reliability, development time, protection, acoustic noise and cost have always been and are key driving factors for decisions on part selection. A sensorless, BLDC motor controller could help put your worries at ease. In a previous post, Milan Rajne...

    How to easily design sinusoidal, sensorless control for 3-phase BLDC motors

    Have you ever imagined that three-phase BLDC motor control solution development could be as easy as building an application circuit using analog ICs, adding a few discrete passive components and the task is done? Is there a solution that removes the burden of complicated motor control software development? In order to answer these questions, let’s first take a deep dive and virtually build a system block diagram...

    The Empires Strike Back (part 2)

    With more and more MCU suppliers pouring onto the battlefield, the entrenched players found themselves under siege. Would MCUs be forced to surrender to the same fate that DRAMs did years earlier in the commodity wars? With so much at stake, MCU suppliers were determined to not let this happen to them, and to not take this onslaught lying down. After all, they still represented the dreadnoughts of the industry with big...
