DOUBLE-LAYER THREE-PHASE STATOR WINDING OF TWO-POLE ELECTRICAL MACHINE |
摘要 |
FIELD: electrical engineering; coil windings for low- and medium-power electrical machines. ^ SUBSTANCE: proposed double-layer three-phase stator coil winding is disposed in three-level slots of two-pole electrical machine, their depth complying with triple height of one of coils placed therein, and in two-level slots whose depth corresponds to double height of one of coils placed in them; number of three-level slots equals that of two-level ones; mentioned slots are alternating so that group of three-level slots equal to number of slots per pole per phase is followed by group of two-level slots equal to number of slots per pole per phase; phase bands of winding formed by some coil sides coincide with those of coils disposed at third (bottom) level of three-level slot groups and at first (top) level of two-level slot groups; other coil sides of all coils characterized by reduced winding pitch are disposed at intermediate (second) layer of three- and two-level slots. Proposed design provides for balancing resistances of all winding phases and makes it possible to avoid lifting of great number of coil sides at a time which is independent of winding pitch reduction and will equal number of slots per pole per phase q. ^ EFFECT: facilitated placement of coil sides in slots. ^ 1 cl |
