FIELD: electricity. ^ SUBSTANCE: reactive switched electrical machine with rotation symmetry consists of stator 1 with even number of poles Zs and coils 2 located on them with polyphase winding and even number of phases, windingless rotor 3 with odd number of poles Zr. According to invention number of stator poles is calculated as per the formula: Zs = 6n where n=1, 2, 3Ç, number of rotor poles Zr is calculated as per the formula Zr = Zs 3. At that adjoining phase windings of stator have alternate polarity; all phase coils within limits of one phase are connected in opposition, magnetic field of active phase is closed through other phases and it allows development of polyphase electrical machine with even number of phases which magnetic structure has rotation symmetry with angle of rotation equal to 120. ^ EFFECT: reduction of converter costs. |
