[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 ...

All major manufacturers of three-phase ac induction motors offer “inverter-duty” or “inverter-ready” models, but while these motors have inverter-rated insulation to protect the windings, the bearings ...

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 ...

Protection against bearing lubrication breakdown due to electrical discharge machining and contamination Static shut-off design to increase reliability by preventing O-ring binding while providing the ...

Doing the right amount of repair in response to a motor failure is a balancing act between speed and thoroughness. May 5, 2014 Doing the right amount of repair in response to a motor failure is a ...
