Two-dimensional electrical machine-generator Invention can be used as electromechanical converter of mechanical energy delivered to one machine input (mechanical) and dc electric energy simultaneously delivered to its other input (electrical) into integrated dc electric energy. In electrical machine containing armature with winding and brush-collector unit of dc machine and rotor with short-circuited winding, over rotor winding of asynchronous motors that are able to rotate around each other, according to this invention a generator winding is additionally laid in armature slots. Output of this winding is connected by means of contact rings and brushes with net of alternating current consumers. |

Controlled two-dimensional electric machine Rotor winding is performed as rotor windings of asynchronous machines with phase rotor in the circuit of which three-phase full-wave regulating thyristor rectifier unit is included. At that, output of this rectifier unit is connected in series with armature circuit using keys of switch unit that is able to perform either serial-additive or serial-subtractive connection with armature circuit depending on sign of armature rotation frequency change direction. |

Electromagnetic clutch comprises housing with coil, friction unit made of a stack of magnetically conducting flat flexible wavy disks having two axially aligned members interconnected through radial cross-pieces. The waves are provided only on the inner ring member of each of the flexible wavy disks. The amplitude of the disk in radial direction is constant throughout the width of the inner ring member. The radii of the waves are determined from the formula R1=(x1/2)2=a1, where x1 is the wavelength over the periphery of the middle diameter of the inner ring member, D1, and a1 is the height of the wave measured from the axial plane of the disk. |
