INDUCTION MOTOR FOR GEARLESS LOW SPEED ELECTRIC DRIVE Russian patent published in 1997 - IPC

Abstract RU 2075814 C1

FIELD: electrical engineering. SUBSTANCE: induction motor stator every phase winding is composed by series-inverted connection of two windings which one is made by coils with radial pitch winding, another part of winding has relative pitch determined as value (1 - 1/k) where k is natural odd number more then 3 which assign motor rotating frequency reduction factor. EFFECT: higher degree of speed reduction factor for electric induction motors of low diameter. 2 dwg
