摘要： Construction of a permanent magnet rotor assembly having a plurality of magnetic poles and comprising a number of magnetic pole pieces arranged in circular array. Two sets of permanent magnets—one set magnetised in circumferential direction of the rotor and the second set providing flux in axial direction of rotor, generating a magnetic flux focused through the pole piece and interacting with the magnetic flux of the stator. End-plates made of magnetic material are present such there is an axial gap between the them and the array of magnetic pole pieces. Circumferentially magnetised magnets are placed in the circumferential gaps between the pole pieces, whereas the magnets providing flux in axial direction are placed in the gaps between the array of pole pieces and end-plates.

摘要： The current invention relates to a magnetic pole assembly, providing flux to an air gap, comprising one or more magnetic pole pieces and one or more sources of magnetic flux. Said one or more sources of magnetic flux lie adjacent to the axial faces and circumferential faces and one of the radially inner face or radially outer face of each magnetic pole piece. Thereby to allow flux created by said one or more sources of magnetic flux to enter the one or more magnetic pole pieces in order to focus the magnetic flux of said pole piece towards and out of the radial surface not having a source of magnetic flux adjacent thereto. Such an arrangement, increases the flux density in the air gap adjacent to said radial surface not having a source of magnetic flux adjacent thereto.

摘要： The current invention relates to a magnetic pole arrangement comprising a plurality of magnetic pole assembles arranged back-to-back along a longitudinally extending axis of rotation X. Each providing flux to an air gap G. Each magnetic pole assembly comprising one or more magnetic poles pieces and two components of magnetic flux. The first component of magnetic flux provided by a plurality of axially magnetised axially displaced magnets arranged in circumferentially extending arrays. The second component of magnetic flux provided by a plurality of circumferentially magnetised magnets circumferentially spaced around the axis of rotation X.
