Abstract

726,102. Reducing noise in electric motors. HOOVER, Ltd. March 17, 1953 [March 19, 1952], No. 7284/53. Class 35. Noise is reduced in an electric motor having an odd number of armature winding slots 8, by the use of shallow unwound slots 19 of substantially the same mouth width situated between them. The slots 19 may be drilled or milled out or filled with lead weights for balancing.
