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 ...

Torque is an important factor in much of the equipment on a factory floor. Measuring torque is often something that's misunderstood, which can lead to over- under-designing of measurement systems.

A little while ago I had one of those immensely annoying – and unwinnable – arguments in an online forum with a guy I’d never met. You’d think the touchy topic was the wisdom of wearing a face mask (I ...

Static Torque: This type of torque acts on an object that is not rotating. Static torque is the twisting force that holds the object in position, preventing it from rotating. For example, the force ...

You almost certainly know the horsepower rating or displacement of your boat’s engine. But some marine-engine manufacturers have begun marketing torque over horsepower. In a break from standard ...

Selecting a motor for a specific application can be a challenging task. Many factors must be considered, including the application’s required voltage, maximum current and diameter, speed, efficiency, ...

Everyone loves to get the latest and greatest. It’s human nature and it afflicts gearheads just like everyone else. Yeah, a top-of-the-line LS7, LS3, or even the new-gen LT mill under your hood is ...

Measuring torque, rotational speed, angle of rotation, and the quantities derived from these variables are increasingly critical in the design of new test benches for use in industrial environments.
