Slow motion motor will run indefinitely

WHILE one group of scientists has been perfecting electrical machinery that will run at higher and still higher speeds, another group has been going to the other extreme by perfecting a timing motor that will revolve only twice a day. By following the same principles the speed could be slowed down to one revolution per year or even less. Theoretically there is no limit to the slowness that could be achieved, according to L. W. Chubb and T. R. Watts research engineers of the Westinghouse Electric and Manufacturing: Company.
