Abstract
864,195. Electric motors. FOSTORIA PRESSED STEEL CORPORATION. Oct. 4, 1958, No. 31742/58. Class 35. [Also in Group XXXIV] An electric motor-driven pump comprises a motor rotor and stator commonly supported by a thin sleeve 30 which extends from a closure plate 16 by which it is supported through the rotor to stator air gap, a pair of spaced bearings 35 supported frictionally within the sleeve and retained in place by an end closure plate 38 and a substantially flat inner plate 40, and a rotor shaft 45 journalled in the bearings and extending through openings in the plates 16, 40 into a pump housing 10. As shown, the sleeve 30, of non-magnetic material such as stainless steel, wholly supports the stator laminations 33 and the rotor bearing rings 35 which latter are preferably of graphite and may have equally spaced openings 36 through which a portion of the pumped fluid flows to act as a lubricant. A motor housing 20 is screwed together with the plate 16 and if for submerged operation a gasket 26 to the pump housing 10 which has fluid inlet and delivery connections 14, 13 and houses the impeller 47. The rotor has short-circuited winding end rings 51 engaging collars 52 e.g. of bronze and pressed on the shaft to act as thrust bearings. The shaft alternatively may be solid. In another embodiment the stator laminations and bearings are secured axially by annular grooves in the sleeve and a snap ring.
