A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

This unipolar stepper motor driver circuit is used to drive a 12V unipolar stepper motor with a current rating of 1.25A. It uses PCA9537 IC, which is a 10-pin CMOS device that provides 4 bits of ...

Motor drivers and their development tools deliver advanced features to improve performance and reduce design complexity.

Different types of motors need different types of drivers. Requirements for a variety of applications. Selecting the right motor driver is crucial to achieving the required functionality and ...

ST Micro's Markus Ekler explains the technology and derives thermal loss equations that can be used to support design decisions for stepper motor driver circuits. One constant trend in the automotive ...

For the first time since 2010, the Formula 1 drivers' championship comes down to three drivers at the season finale. Here's ...

I have been trying Fritzing, the free schematic capture and pcb layout tool, which also does breadboard layouts too. It is good? The short answer is excellent – particularly as it seems to be the work ...

A teacher I know is stuck, with only npn transistors in the supply cupboard and the need to create a reversible motor drive for an Arduino project. Reversing ‘bridges’ have four switches (relay ...

Father of Lotus, Colin Chapman, said his secret to engineering racing and sports cars was to "add lightness." An intriguing phrase, to say the least. And one that might well have been lost in time by ...
