Abstract:

A multiple impeller flow inducing device in which driver coils are intermittently energized in timed relation to rotation of the impellers to interact with permanently magnetized portions of the impeller to rotate the same. The impellers can be rotated in opposite directions or in the same direction. A two section impeller construction allows each section to be magnetized in opposite pole orientation and when assembled creating alternate pole orientations of successive portions, arcuate segments forming a shroud or the type of blades can be magnetized to provide the impeller magnetized portions. Stator guide vanes can be interposed between successive impellers.

US Classification:

310178, 310268, 31015637, 31015664

Abstract:

The invention refers to magnetoelectric machines and comprises a rotor made in the form of at least two disks, the magnetized disks have circumferential arrayed like poles and an axially magnetized polygon or cylindrical magnet placed between the disks. The stator comprises a winding selected from the group consisting of a coil winding and a wave winding coils that are distributed over the circumference and are installed predominantly in the space between the rotor poles provides for the possibility of the end face interaction with the rotor poles. Each of at least two disks could be made of a non-ferrous material with embedded magnets, and rotor further comprises ferrous metal plates, each of the plates is attached on an outer surface of each disk and comprises a ferrous metal cylinder for interconnecting a magnetic flux between ferrous metal plates. The rotor could be made as a multi-sectional unit. The disks could be made integral with a magnet in such a manner that they serve as magnet's poles.

US Classification:

310208, 310179, 310254

Abstract:

An electric drive comprising a stator with at least two ring-shaped windings and controllers, and a magnetized rotor with an axis of rotation. Each of said windings comprises at least one coil layer with circumferentially arrayed coils located around said axis, and a layer of electro-insulating material, and each winding is electrically connected to a power source through an individual controller. At least two said windings are electrically connected by their controllers in parallel, with the possibility to function jointly and/or independently. At least two nearest windings are located in such a way that two said coil layers belonging to the different windings are separated by an additional layer of electro-insulating material. The coils of said nearest coil layers of different windings are made the same in transparent view, so that the distances between corresponding parts of said coils of said nearest windings are equal to the thickness of said additional layer of an electro-insulating material. At least two said nearest windings are made as parts of a common multi-layer printed circuit board.

The circuit board on each side comprises one layer of circumferentially arrayed coil windings arranged in pairs, thus each pair made as a spiral that extends from a center of a start coil winding to a center of an end coil winding with the same turn direction of the spiral in relation to each of centers. The layers are the same in transparent view and shifted angularly in such a way thus centers of the start coil windings from one side of the circuit board coincided and electrically connected by via's with centers of the end coil windings on the other side of the circuit board.
