The electric motor is,of course,the very heart of any machine it drives.If the motor does not run, the machine or device will not function. The importance and scope of the electric motor in modern life is attested to by the fact that electric motors,numbering countless millions in total,convert more energy than do all our passenger automobiles.Electric motors are much more efficient in energy conversion than automobiles, but they are such a large factor in the total energy picture that renewed interest is being shown in motor performance.Today's industrial motors have energy conversion efficiency exceeding 95% in larger horsepowers.This efficiency, combined with unsurpassed durability and reliability,will continue to make electric motors the "prime movers"of choice for decades to come.
