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 ...

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 ...

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 ...

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, ...

Try this for kicks. The next time you’re surrounded by your gearhead buddies, ask them to explain the difference between horsepower and torque. The participants will immediately divide into “pro ...

There's more to the nuts and bolts fastening the most critical components on your race car than simply getting them "tight enough." Bolts don't work by simply clamping down on something thanks to the ...

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.
