<p>The stator comprises a coil flux guide (1) in some grooves of which are arranged coil groups (2, 3, 4; 2?1, 31, 41¿) of two three-phase windings connected in delta and star configuration. The magnetic induction vectors (B¿UlV1?, BV1W1, BW1U1; B1U1; B1V1, B1W1) of each of the coil groups (2, 3, 4; 2?1, 31, 41¿) intersect the axis (5) of the coil flux guide (1). The coil groups (2-2?1; 3-31; 4-41¿) of like phase in the transverse section of the stator overlap and are offset by 30 electrical degrees, while the three-phase windings are of comparable power. The combination of features ensures chronological and geometrical orthogonality of pairs of magnetic induction vectors (B¿U1V1?-B1W1; BW1U1-B1V1; BV1W1-B1U1) of the coil groups (2, 3, 4) in one phase of one three-phase winding and of the coil groups (3?1, 41, 21¿) in the next phase of the other three-phase winding.</p> |
