When one power generating system purchased 48 of these large, two-pole motors to drive boiler-feed pumps, it was another case of demonstrated confidence in Elliott motor design and construction. These motors have proven themselves with their ex ceptionally high efficiency and power factor. With their Fabrt-Steel construction, the frame members are joined by the latest welding techniques. This results in high strength and rigidity with light weight. The rigid welded stator frame and bearing bracket construction reduce vibration and noise and maintain uniform air gap. Every motor element reflects this careful engineering and work manship. Get all the facts in Bulletin PB 7000-1*151. Write Elliott.Company, Ridgwoy, Pa.
