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 ...

[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 ...

When it comes to assuring that a motor provides consistent service for the longest time possible, it’s important to pay attention to the bearing system. Bearing system failures are one of the most ...

Electric motors fail more often than they should. Sometimes, it is not the motor’s fault. The real issue lies deep within—where current leaks through the bearings. That is where insulated bearings ...

All major manufacturers of three-phase ac induction motors offer inverter-duty models with insulation sufficient to protect the windings, but the bearings are often left vulnerable to damage — ...

We see our share of pitches for perpetual motion machines in the Hackaday tips line, and we generally ignore them and move along. And while this magnetic levitation motor does not break the laws of ...

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 ...

Did you know that Tesla relies on SKF ceramic bearings for the Model S motor? Should you care? Well, in this video both SKF and Tesla discuss the importance of something so seemingly minor as motor ...

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 ...
