Abstract: A manufacturing method for permeable bandages and magnetic cores for rotors of electrical machines is proposed. The proposed method relies on winding with insulated metal preferably permeable wire or ribbon with high pretension and maintaining pretension in the wire or ribbon during manufacturing steps. The proposed method could be especially useful for high-speed electrical machines.

Abstract: Winding diagrams, in which there is no intersection of endwindings in space and which are suitable for interchangeable windings of electrical machines, are considered in the proposed invention. Winding diagrams of a three-phase, two-layer concentric winding with a 120° phase zone and a three-phase, three-layer concentric winding with a 180° phase zone are considered. The scheme of a three-phase two-layer concentric winding with 120° phase with a linear distribution of turns in phase coils is offered for improvement of MMF distribution. The scheme of a three-phase, three-layer concentric winding with 180° phase zone with trapezoidal distribution of turns in phase coils is also proposed for improvement of MMF distribution.

Abstract: This invention presents a novel method for designing and manufacturing electrical windings for electrical machines. The presented manufacturing technique gives possibilities for an increased filling factor compared to conventional technique and improved heat transfer through application of thermally conductive compounds. The ready winding represents a solid body and has the strictly determined geometrical form. The slot part of the ready winding represents rods. These rods are the composite material consisting of coils of the insulated copper wire and any compound. The cross section of these rods precisely coincides with the cross section of slots of stator and differs only on the value of the tolerance necessary for assembling. End parts of the ready winding represent rings from a composite material. Visual appearance of a winding reminds the squirrel cage of a rotor of the asynchronous motor. The specified technology provides high precision of manufacturing of a winding.

Abstract: This invention presents a novel method for designing and manufacturing electrical windings for electrical machines. The presented manufacturing technique gives possibilities for an increased filling factor compared to conventional technique and improved heat transfer through application of thermally conductive compounds. Proposed winding schemes avoid intersection between different winding layers in the end-winding region. This helps automating winding production, simplifies insulation between winding layers and, if this is necessary, simplifies insertion of the winding. Both these factors affect the cost and reliability of the winding. This method is applicable for a broad range of electrical machines and allows easy automation of the winding process.
