摘要： An induction device, such as a transformer or reactor, comprises windings (53) of different phases arranged around magnetic core limbs (52). The magnetic core limbs are connected by at least one body (51) formed from magnetic particles in a matrix of a dielectric material. In alternative embodiments the device is substantially spherical or cylindrical. Regulating windings mounted on inner and outer magnetic core parts may be transferable therebetween.

摘要： A distributed air gap material for an induction device in power systems for minimizing fringe losses, mechanical losses, vibration and noise in the core. The distributed air gap material occupies a selected portion of the core and is formed of a finely divided magnetic material in a matrix of a dielectric material. The air gap material has a zone of transition in which the magnetic permeability values vary within the air gap material.

摘要： The invention relates to an electrical machine having a first magnetic core provided with winding, and a flux-generating device comprising at least two flux-generating variable magnetic flux elements. These are arranged to vary the flux locally so that the local flux variation can be described by a magnetization vector that moves in substantially one plane. The application also relates to a method and a device for controlling magnetic flux in such an electrical machine. The invention also relates to the use of such a machine and a system including such a machine.
