Here’s a nice little circuit that will drive a motor and allow you to stop its rotation, giving your robot a set of brakes. It’s part of [JM’s] post about the in’s and out’s of building ...

I have a problem. Somehow, I obtained this Watts Up Pro device. Essentially, it calculate the power usage (in Watts) for anything that is plugged into it. Very cool, but someone needs to stop me. I ...

Scientists hoping to design a tiny, spinning motor capable of assisting in brain surgery are cribbing secrets from an unlikely source: Pizza-dough throwers. Scientists hoping to design a tiny, ...

Pizza-Dough Throwers Teach Scientists How to Build a Nanoscale Motor Scientists hoping to design a tiny, spinning motor capable of assisting in brain surgery are cribbing secrets from an unlikely ...

So, what is a "tank turn?" It's when a tracked vehicle, such as a tank, powers its tracks in opposite directions—one set of tracks go forward, the other backward—in order to spin in place. Rivian's ...

Brushless motors have a lot of advantages over traditional brushed motors. However, testing them can be a bit of a pain. Because the resistance of the motor’s coils is usually very low, a standard ...

Ask any system designer to name the top three reasons for specifying a variable-frequency drive (VFD), and you probably won't hear a lot of “maintenance cost reduction” responses in return. Instead, ...

Let us begin this session by revisiting a nostalgic motor control IC—the AN6651—designed for rotating speed control of compact DC motors used in tape recorders, record players, and similar devices.

Scientists at the Korea Institute of Science and Technology (KIST) have developed a new class of lightweight, highly conductive carbon nanotube (CNT) wiring that does away with copper and aluminum ...
