SLOTLESS CYLINDRICAL STATOR OF ELECTRICAL MACHINE Russian patent published in 2003 - IPC

FIELD: electrical and electromechanical engineering; induction motors. SUBSTANCE: stator has laminated frame yoke 1 and distributed layer 2 formed by winding stack modules in the form of interleaving longitudinal electric-steel laminations 10 and winding conductors disposed at lower and upper spatial levels; frame yoke 1 is assembled of ring-shaped steel laminations 4 with supporting bosses 5 inwardly oriented to gap and interconnected electric steel strip monolithic rings 6 wound on edge and provided with slits 7 filled with ferromagnetic adhesive compound. Reinforced ferromagnetic adhesive compound interlayer is fitted between frame yoke 1 and active distributed layer 2 and the latter is assembled of different winding modules some of them having more densely compacted conductors at upper level of this layer 2 due to use of intermodule space. EFFECT: enhanced performance characteristics at reduced overall dimensions. 1 cl, 2 dwg
