Electric generator for wind-driven plant Electric generator is proposed for a wind-driven plant, comprising a stator, a rotor with a base and a cover, magnets and a flat coil. The magnets are installed on the cover and the base along a ring with a certain gap, and there is a flat coil installed between the magnets with a minimum gap, which is closed by circular plates at two sides. The flat coil is made of three windings located in radial gaps of a matrix. The matrix consists of an outer and an inner parts. Circular plates and the matrix are made of a dielectric non-magnetic material, and the base with the rotor cover are made of a magnetically conductive material. The magnets on the cover and the base are arranged as alternating with opposite poles, at the same time the magnets installed on the cover and the base opposite to each other also have the opposite poles. |

Torque transmission assembly for superconducting rotating machines Proposed rotor assembly includes superconducting winding assembly located in cryogenic zone of rotor assembly. The above rotor assembly includes torque transmission assembly which according to this invention includes the first and the second pipes which are located with a radial gap outside the assembly of superconducting winding and which pass along longitudinal axis of rotor assembly. Besides, superconducting rotating machine containing such torque transmission assembly is proposed. |

Electric motor with multilayered rhomb-shaped windings Present invention relates to electrical engineering, particularly to electric motors, with windings with an air core, and can be used in rotors of dc motors, as well as in stators of electronic-commuted (EC) motors. The electric motor contains a winding with an air core, made from several separate windings, made from conductors. The separate windings are superimposed on each other and have such a shape that there is shifting in the region of at least two opposite corners. According to the first version of the invention, half the sides of the separate windings is in an inner hollow cylinder, and the other half is in an outer hollow cylinder without overlapping the inner hollow cylinder. According to the second version, half of the sides of separate windings is in a first plane, and the other in a second plane, without overlapping the first plane. The overlapping separate windings together form a flat winding, which comprises a first plane and a second plane. The separate windings are provided with an extra amount of conductor material as allowance in the shifting region, which forms preferably a U-shaped or loop-shaped bulge on the inner contour of the separate windings. |
