New Gearmotor Sizing Guide from Bison Gear and Engineering Corp.
Selecting the proper gearmotor is a matter of matching output speed and torque to an application's needs. RPM is determined by the driven machine's requirements and should be known. That leaves torque to be determined. For machines where the load is primarily friction, running torque and starting...

Proximity Sensors
to detect, the upper switching range of these devices is about 50 Hz. Primary applications are in bulk-handling machines, level detectors, and package detection. One advantage of capacitive sensors is that they are unaffected by dust or opaque containers, allowing them to replace optical devices. A typical...

Cool Coatings Let Engines Run Hotter
environments include serpentine interior-cooling passageways and surface-film cooling schemes. However, many hot-section components now perform in environments where operating temperatures exceed the theoretical melting point of the component material, typically a superalloy. Here there's a critical...
