UNIVERSAL COMMUTATORLESS ELECTRICAL MACHINE Russian patent published in 1999 - IPC

FIELD: electrical engineering; DC or ac motors or generators. SUBSTANCE: electrical machine has frame, rotor with magnetic systems, and stator with multiturn running windings; novelty is that there is at least one module whose rotor shaft carries hub with external and internal magnetic systems and its stator with even or odd number of multiturn running windings is placed between magnetic- system poles; control system for running layers of multiturn winding is placed inside stator and electrically coupled with electronic switches; rotor of each module has slots to provide interaction with other modules. EFFECT: improved efficiency, reliability, and safety; simplified design. 5 cl, 14 dwg
