Such rotors fall apart if spun much faster than a few million revolutions per minute, limiting the materials that can be studied with such systems. But now, researchers at MIT have developed a method ...

Hunter’s OCL430HD rotor lathe is designed to improve medium- and heavy-duty service by machining the rotor on the vehicle. Hub-mounted service eliminates the need to disassemble the hub to remove the ...

Rotor heads for helicopters are large and awkwardly shaped objects, and machining them from a forging is a challenging operation. When Leonardo Helicopters decided to bring manufacture of rotor heads ...

An ac induction rotor starts as a stack of steel plates stamped with slots. Either molten aluminum is injected into the slots and flowed over the ends, or (in very large motors) bars of aluminum or ...

• Induction motors employing copper rotors can be smaller than equivalent versions with aluminum rotors. • Copper rotors exhibit lower losses than aluminum which lets them run cooler and be more ...

MIT researchers developed a method for making tiny, precise rotors out of pure diamond crystal (far right cylinder), which can spin at far higher frequencies than rotors made from conventional ...
