Smaller, streamlined electronics make lubricant-free, low-friction magnetic bearings feasible for more rotating machines. • Magnetic bearings support rotating shafts in five axes without solid or ...

A ROTATING shaft can exhibit torsional vibration when, because the dynamic coefficient of friction is less than the static value, the frictional force at the bearings supporting the shaft decreases as ...

They're lightweight with straightness and lateral stiffness that boost stability at higher speeds. Line shafts, also known jackshafts and torque tubes, span long distances to connect other power ...

Proceedings of the Royal Society of London. Series A, Mathematical and Physical Sciences, Vol. 292, No. 1431 (Jun. 14, 1966), pp. 537-561 (27 pages) The results are given of experimental and ...

Rotary encoders sense changes in the position of a rotating shaft, then generate signals that send speed, direction, and position information to a receiving device such as a counter, drive, or ...

From tiny hysteresis motors that drive electric clocks to huge synchronous motors that develop more than 50,000 hp, the alternating current (AC) motor has become an indispensable part of everyday life ...
