Abstract

691,620. Cores for dynamo-electric machines. BRITISH THOMSON-HOUSTON CO., Ltd., and RIDDLE, R. G. Oct. 2, 1951 [Nov. 6, 1950], No. 27063/50. Class 35. A shaded-pole 1-phase induction motor has salient poles so shaped at their polar face that a graded air gap is provided. The Figure shows a motor in which the air gap between stator and rotor is minimum at a at the centre of the pole and a maximum at b at the pole tips.
