An electrical rotating machine having a rotor comprising a shaft made from non-magnetic material, a plurality of pole pieces made from magnetic material and surrounding the shaft, with permanent magnets fixed in receivers by wedges cooperating with the pole pieces to block radially outward movement of the magnets.

Electrical machine having a rotor specially adapted to high speeds

An electrical rotating machine in which the laminated magnetic circuit of an external stator includes a stack of yokes each made from a magnetic metal sheet and disposed substantially parallel to a plane perpendicular to the axis and a plurality of teeth disposed inside the yokes, the teeth each being made from a magnetic metal sheet and disposed substantially parallel to a plane perpendicular to the axis, the teeth being stacked and the stacks of teeth delimiting slots, the teeth being bound with the yokes by gluing with resin.

Stator for an electrical rotating machine

The method and device for machining a sheet and controlling the thickness between the opposite faces of said sheet in a press between sheet engaging surfaces, at least one of which is a bearing surface of narrow width extending across the width of the sheet, in which the space between them is controlled to modify the thickness of the sheet in a series of successive steps which include moving the sheet relative to the sheet engaging surfaces, stopping the movement of the sheet and moving the sheet engaging surfaces against the sheet to compress the sheet to a predetermined thickness and controlling the stepped movement of the sheet and the movement of the sheet engaging surfaces in alternate and successive sequences.

Machining of sheet by compression without removal of material

A method and device for machining a sheet contains a jaw equipped with two plates mounted opposite each other in order to delimit a calibration opening between said plates in which it is possible to vary the spacing between plates. A clamp is provided for grasping the sheet, and the clamp is moved in relation to said plates. The movement of the clamp and the relative position of said plates is coordinated, so as to slide the sheet in relation to said plates while the distance between said plates is controlled. The process includes pulling the sheet by one end so as to separate an initial section from the plane containing the calibration opening and thus pass the sheet through the calibration opening while the plates are kept supported against said sheet, so as to vary continuously the thickness of the sheet while the sheet is passed through the calibration opening.
