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： The invention relates to electrical engineering and electric machines with stator-mounted magnets, and can be used in electric drives for machines and mechanisms as well as in electric power generators. A brushless machine contains a rotor comprising a shaft and at least one toothed fragment thereon, said toothed fragment having teeth positioned along the boundary of a gap. A stator comprises a toothed magnetic core and a winding, the coils of which are placed in the slots of the magnetic core of the stator. A multipolar magnetic system is made of a hard magnetic material, positioned between the rotor and the magnetic core of the stator, affixed to the stator and magnetized in such a way that an equal number of alternating opposite poles are arranged on the surfaces of the stator teeth, which teeth face the gap along the direction of rotation of the rotor. The stator is in the form of a solid of revolution with a plurality of teeth positioned along the axis of rotation of the rotor. Each coil of the winding is placed in one stator slot. Only the teeth of one toothed fragment of the rotor are positioned over each stator tooth. The number of teeth on each of the toothed fragment equals half of the number of poles found on a single stator tooth. The essence of the invention consists in increasing the power density of an electric machine and decreasing the mass of active materials.

摘要： A variable reluctance resolver is provided with an output winding having a reduced effect from externally introduced leakage magnetic flux. A variable reluctance resolver is provided with a resolver excitation winding and a resolver output winding wrapped around multiple stator magnetic poles (610 through 629) which respectively output rotary angle X and Y components as a rotor turns. Windings are wound such that the polarities of output voltages on output windings wound around a row of three or more stator magnetic poles will be the same; all of the output windings are divided into an even number, two or greater, of groups (G1,G2,G3,G4) and output windings are serially connected in such a way that adjacent group output voltage polarities mutually differ. Also, the number of turns inside the aforementioned groups is wound so that the number of turns of output windings positioned on each of the adjacent group sides is smaller than the number of turns of the output windings positioned on the inside of the aforementioned output windings in the relevant group.

摘要： Disclosed is an electromagnetic circuit wherein coils are wound in a forward(clockwise) direction and in a reverse (counterclockwise) direction and semiconductor switches are mounted in front of the respective coils so that a non-induction line becomes a polarity-converting point of an alternating magnetic flux by controlling currents. Accordingly, a mechanical dynamic power of a high torque can be obtained by electrical energy.
