In recent years, increasing rotational speed is required for reducing size and cost of systems applying high-output motors. However, it is difficult for mechanical bearings to suspend a shaft of the high-output motor rotating at high speed due to friction and wear caused by mechanical contact. On the other hand, magnetic bearings (MBs) are useful for shaft suspension of the high-output motor rotating...
Highly pure pig irons were produced from powdered iron ores and carbons in a multimode microwave reactor. Microwaves create two different steps that enhance chemical reactions at the grain boundaries very rapidly to finish the reduction process. The visible light spectroscopic monitored the progress of the reactions. The powders absolve and radiate the continuous spectrum of blackbody emission under...
