[RimstarOrg] has brought us an oldie but goodie this week. He’s built a ball bearing motor, a design which has been causing engineers and scientists to squabble for decades. [RimstarOrg] used a ...

Bearing-related problems are among the most common causes of motor failures. Solving those problems will reduce motor failures. Did you know bearing-related problems cause more than half of all motor ...

Inverters used to control a motor’s speed or torque — also known as variable frequency drives (VFDs) or adjustable speed drives — can induce unwanted motor shaft voltages that cause premature motor ...

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 ...

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 ...

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, ...

HYPROSTATIK SCHÖNFELD spindle bearings help grinding machine operators achieve ultra-precise finishes: When grinding, the best surface finishes are achieved if the tips of the abrasive particles ...

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) ...

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 ...
