Abstract

876,613. Electric motors. FIRTH CLEVELAND Ltd. July 2, 1957 [July 7, 1956; Dec. 7, 1956], No. 44293/60. Divided out of 876,611. Class 35. [Also in Groups X, XXVI and XXXIII] Fig. 5 shows a motor construction in which two squirrel-cage rotors 55, 56 are provided with a common shaded-pole stator 52 of H shape having a stator winding 52a on the crosslimb 53. The motor shown in Fig. 6 comprises two rotors 66, 67 driving fan impellers 60, 61 and mounted on a shaft 72 journalled in bearings 73 which are mounted in a tube 74 carried by a stator 62. Stator 62 is supported on a pillar 63 and carries laminations 64a, 64b adjacent the rotor laminations 70, 71. A common stator winding 65 is provided. A rubber ball on the end of a steady 75 can rest against some adjacent part to give additional support.
