摘要： A permanent magnet rotor shaft assembly for a high speed electrical machine provides a permanent magnet cylindrical core having a longitudinal axis, the cylindrical core being axially compressed by first and second end shafts and being radially compressed by a sleeve made of a non-magnetic high strength metal. At least one of the first and second end shafts includes, facing the cylindrical core, a central shoulder head that cooperates with a mating central recess made in a central portion of a front face of the cylindrical core. An easy concentric alignment of the first and second end shafts with the permanent magnet cylindrical core is allowed while inserting the sleeve and the stiffness of the assembled set is enhanced.

摘要： The invention concerns an electrical installation providing an apparatus, a three-phase inverter and a control device, the inverter being adapted for generating a three-phase current presenting a first frequency for operating the apparatus and an undesired frequency component presenting a second frequency. The control device is adapted for measuring a parameter of each phase of the current, the measured parameters forming a measurement vector, and for calculating a Clarke transform, providing a first vector represented in a first basis of a two-dimensional vector space, of the measurement vector. The control device is adapted for generating a representation of the first vector in a second basis of the vector space, the second basis rotating at the second frequency with respect to the first basis.

摘要： This radial position sensor measures the radial position of a rotor within a stator. The sensor provides measuring means for measuring the position of the rotor along a first axis radial to a rotation axis of the rotor and along a second axis perpendicular to the first axis. The measuring means includes four magnetic poles, among which two poles are diametrically opposed along the first axis and two other poles are diametrically opposed along the second axis, the magnetic poles distributed, on the inner surface of the stator, with alternating magnetic polarities around the circumference of the stator. Alternatively, the measuring means includes eight magnetic poles distributed, on the inner surface of the stator, with alternating magnetic polarities around the circumference of the stator and are arranged so that each pole deviates by an angle of approximately 30° from the nearest axis among the first axis and the second axis.
