In this invention a method of manufacturing and structure of prestressed composite reinforcements for cylindrical liners is presented. The method relies on creating deep precompression in the liner compensated by according pretension in the reinforcement. This method allows efficient use of mechanical properties of material of the liner and reinforcement and can provide a substantial mass reduction of the overall component.

Method of manufacturing and structure of prestressed composite reinforcements

An electric machine having a hybrid bearing for the purpose of supporting a rotor with respect to a stator, the hybrid bearing consisting of a radial bearing, taking the form of a fluid dynamic bearing, and an axial bearing that is made up of magnetic elements, wherein the magnetic elements comprise at least one permanent magnet and one flux guide element that are disposed so as to be located opposite each other in a radial direction.

Electric machine having a hybrid bearing

A stator arrangement and a rotor arrangement for a transverse flux machine. The stator arrangement comprises an annular stator back yoke having a number of stator poles designed in the manner of claw poles. The rotor arrangement includes number of rotor poles designed in the manner of claw poles and connected to each other to form an annular rotor body enclosing a unipolar ring magnet magnetized in an axial direction. In the stator arrangement, the stator back yoke includes a first laminated stack of metal sheets whose laminations are stacked in an axial direction, and the stator poles include a second laminated stack of metal sheets whose laminations are stacked in a tangential direction. In the rotor arrangement, the rotor poles include laminated stacks of metal sheets whose laminations are stacked in a tangential direction.
