[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 ...

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 — ...

Universal bearing supports have precision mounting surfaces predrilled for foot mounting. Flange bearing supports have a compact envelope with a precision pilot diameter and flange face for accurate ...

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 ...

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 ...

For some time now, researchers have been managing to craft ever-smaller devices, though they’re approaching the problem from two directions. Some researchers are etching small features into chips to ...

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 ...

Efficient dc motors come in 50/65-mm size The RE 50 and RE 65 industrial type brushed dc motors output 200 and 250 W and have commutation side protection with a sealed aluminum housing. Cable outputs ...

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 ...
