Engine bearings do many things. They support moving parts like crankshafts and connecting rods, but they also play a role in determining an engine's oil pressure and protect the crankshaft from being ...

There's more to selecting a motor than meets the eye. Motors typically are grouped into three categories. General-purpose motors are designed around industry standards and feature standard operating ...

This schematic shows a 12-MW, 9,500-rpm induction motor with oil-film bearings that drives an oil-pipeline pump. Like other high-speed machines, it has a specialty rotor, reinforced bearing housing, ...

Most all the spinning parts on our vehicles would simply not function well without one simple invention—bearings. You’ll find them in the engine, transmission, transfer case, and axles. Bearings allow ...

The experts at eMotors Direct outline how VFD’s can damage bearings and discuss preventative measures to prevent VFD induced bearing damage Electric motors fitted with VFDs (Variable Frequency Drives) ...

When machine vibration increases, one of the first questions to ask is: “Is a failing bearing causing the vibration?” In the case of rolling element bearings, it’s not difficult to separate vibration ...

Electric motors fitted with variable frequency drives are at risk of bearing damage due to a build-up of current in the rotor that discharges through the shaft, damaging the lubrication and bearing ...
