MULTIPHASE CROSS-FLUX ELECTRICAL MACHINE Russian patent published in 2002 - IPC

FIELD: electrical engineering. SUBSTANCE: multiphase electrical machine with single-ended stator and rotor has mainly U-shaped yokes corresponding to winding phases and primarily I- shaped yokes all disposed in stator carrying annular windings and alternately placed in tandem in one respective plane; its rotor mounts flat permanent magnets on its surface adjacent to yokes and ensures ring-type closure of magnetic flux; permanent magnets are arranged in rows mechanically displaced relative to each other and annular windings carry accordingly shifted currents; U-shaped yoke bars of each phase of winding are bent in opposition to elbow shape in each plane and adjacent phase bars of winding disposed in same plane are interconnected. EFFECT: reduced flux leakage path; reduced size of machine. 8 cl, 2 dwg _
