摘要： The invention relates to an electric machine comprising a rotor (10) and a stator (20). The rotor (10) has magnet pockets for receiving permanent magnets (55, 56, 85, 86), and the magnet pockets comprise at least one first pair of magnet pockets (50, 51) and a second pair of magnet pockets (80, 11). The second pair (80, 81) is arranged further inwards than the first pair (50, 51) when viewed in a radial direction with respect to a rotational axis, and the magnet pockets of each pair of magnet pockets (50, 51, 80, 81) are arranged symmetrically to one another with respect to an axis of symmetry (45), wherein the axis of symmetry (45) runs in the radial direction and through the center of the rotor (10). The magnet pockets of each pair of magnet pockets (50, 51, 80, 81) are arranged such that the distance of each magnet pocket to the axis of symmetry (45) increases as the distance to the circumferential edge (110) of the rotor (10) decreases. The magnet pockets of the first pair (50, 51) are arranged at a first mechanical angle to one another, and the magnet pockets of the second pair (80, 81) are arranged at a second mechanical angle to one another. The invention is characterized in that the first angle ranges from ca. 100° to ca. 140°, in particular from ca. 120° to ca. 140°, and the second angle ranges from ca. 65° to ca. 112°, in particular from ca. 88° to ca. 112°.

摘要： The present invention relates to electrical engineering, particularly to synchronous reluctance machines, and can be used in electrical drives for machines and mechanisms, as well as in electrical power generators. The synchronous reluctance machine comprises a stator with a winding arranged within stator slots, and a rotor mounted to provide a gap between the rotor and the stator, the rotor being rotatable with respect to the stator and comprising radially alternating magnetically permeable layers and flux barriers, wherein each barrier comprises at least one peripheral end extending towards the circumferential rotor surface and the angular pitch of the peripheral ends decreases in circumferential direction from the peripheral ends of the outer barriers towards the peripheral ends of the deepest inner barriers among at least three circumferentially sequential peripheral ends, wherein at least two of said ends are inner barrier ends. This results in improved energy characteristics of the reluctance machine, in particular power factor, efficiency and specific power thereof, for the same number of flux barriers. This is further achieved by a synchronous reluctance machine comprising a stator with a winding arranged within stator slots, and a rotor mounted to provide a gap between the rotor and the stator, the rotor being rotatable with respect to the stator and comprising radially alternating magnetically permeable layers and flux barriers, the gap is increased by 15-400% between the surface of the most external magnetically permeable layer and the stator compared to other sections of the gap.

摘要： An electric motor includes a stator having a stator surface and a rotor rotatable relative to the stator. The rotor includes a plurality of poles, each of which is defined by a pair of magnets positioned in a V-shaped arrangement having a vertex positioned radially inward. The magnets present a mechanical pole angle of the corresponding pole. The rotor also includes a rotor surface that is opposite the stator surface. The rotor surface includes a plurality of circumferentially-spaced pole segments, each of which spans a respective mechanical pole angle. The rotor also includes a plurality of longitudinally extending recesses, each of which is positioned between adjacent pole segments.

摘要： A permanent magnet motor is provided that produces variable magnetic flux. The motor may include two different types of permanent magnets with different coercivities. The magnetic state of one of the magnets may be altered during use. In one state, the effective magnetic flux of the motor is greater, and in another state, the effective magnetic flux of the motor is less.

摘要： A consequent-pole-type rotor includes a first rotor core having a first insertion hole, and a second rotor core having a second insertion hole, the second rotor core being stacked on the first rotor core such that the first insertion hole and the second insertion hole together form a space accommodating a permanent magnet. The first insertion hole has an opening at a first circumferential position of the first rotor core, and the second insertion hole is occluded at least at a second circumferential position of the second rotor core. The second circumferential position corresponds to the first circumferential position.

摘要： A stack formed by stacking a plurality of blanked members includes a first blanked member forming an outermost layer of the stack and a second blanked member located adjacent to the first blanked member. A through is hole formed in the first blanked member, and an area of the through hole has a length that is greater than a width. A connecting tab having a chevron shape is formed in the second blanked member so as to be fitted into the through hole of the first blanked member. On opposite sides of the through hole, notches are recessed outward from an inner-wall surface of the through hole in opposing directions that correspond to the width of the area of the through hole.
