In a speed controller, the motor’s speed (or velocity) is being controlled. There is an element that detects speed, whether it be a tachometer or some sort of encoder. This monitoring element provides ...

Electric clutches may not be always the engineer’s first choice when looking at torque-control solutions. Electric motor drive systems, pneumatic clutches, or even friction spring types are thought of ...

I do a lot of new car testing at the racetrack, and the more at-the-limit testing I do, the more I’ve come to realize that “Off” rarely means 100 percent off when it comes to electronic stability ...

Motors account for at least half of the energy consumed in the U.S. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall ...

A brushless-DC motor is common in ceiling fan and pan-tilt-zoom (PTZ) camera designs. But you can’t use the same brushless-DC motor solution for both of these end products. A ceiling fan driver ...
