Abstract: An arrangement to set up and to ensure an air gap in an electrical machine, like a generator, is provided. The electrical machine includes a stator arrangement and a rotor arrangement. The rotor-arrangement rotates around a longitudinal axis. At least parts of the rotor arrangement interact with parts of the stator arrangement to generate electrical power. An air gap is defined by the distance between the parts of the rotor arrangement and the parts of the stator arrangement. The parts of the stator arrangement are opposite to the parts of the rotor arrangement along a certain length. The cross-section of the air gap changes along the certain length, so that the air gap is not uniform in view to the referred certain length.

Abstract: A deflection resistant wind turbine generator having a stator arranged about an axis and a rotor operably mounted with respect to the stator to generate electricity. The rotor is rotatably communicating with wind turbine blades rotating substantially about the axis and the rotor and the stator are configured to maintain an airgap therebetween. The stator and the rotor have selectively engageable surfaces that maintain a substantially stable airgap and permit rotation of the rotor during engagement. The engageable surfaces engage when the rotor deflects to a predetermined amount of deflection.

Abstract: A machine includes a moving part and a direct drive for moving the moving part. The direct drive includes a stator and an armature unit which interacts with the stator. A coupling device couples the armature unit to the moving part to allow a movement of the moving part in relation to the armature unit. The direct drive further includes a spacer device to maintain a distance between an active region of the stator and an active region of the armature unit, thereby defining the air gap between the stator and the armature unit.

Abstract: A torquer apparatus generally comprises a reaction-gyro sphere consisting of a concentric assembly of a substantially spherical rotor and a substantially spherical stator. This is implemented in the present invention as a rotor with magnetic poles such that, when radially projected on a concentric octahedron, the same symmetrical pattern is obtained on all faces of said octahedron, the polarity of the poles projected on two adjacent faces of said octahedron being opposite and a stator with at least twenty poles magnetized with coils and such that, when radially projected on a concentric icosahedron, the same symmetrical pattern is obtained on all faces of said icosahedron, said stator being-in nominal position-concentric with said rotor. Real-time measurements, or equivalent information, of the position of the rotor with respect to the stator are obtained together with exported torque from the stator, or the orientation of the rotor with respect to the stator. A controller controls the current in the coils of the stator poles based on said measurements, or said equivalent information, such that the rotor is magnetically held in said nominal position, and that the desired torque is exported.

Abstract: A permanent magnet rotating electric machine comprises a stator having stator windings wound round a stator iron core and a permanent magnet rotor having a plurality of inserted permanent magnets in which the polarity is alternately arranged in the peripheral direction in the rotor iron core. The rotor iron core of the permanent magnets is composed of magnetic pole pieces, auxiliary magnetic poles, and a stator yoke, and furthermore has concavities formed on the air gap face of the magnetic pole pieces of the rotor iron core of the permanent magnets, gently tilting from the central part of the magnetic poles to the end thereof. In a permanent magnet rotating electric machine, effects of iron loss are reduced, and an electric car using highly efficient permanent magnet rotating electric machine are realized.
