    摘要: Method and system for determining core losses in a permanent magnet synchronous motor, comprising a measurement of the losses of the motor with the motor not connected to a load, and a deduction of the core losses of the motor from the losses of the motor.
    The motor is placed in an over-fluxing state during the measurement of the losses.

    摘要: A permanent magnet rotor shaft assembly (100) for a high speed electrical machine comprises a permanent magnet cylindrical core (101) having a longitudinal axis, the cylindrical core (101) being axially compressed by first and second end shafts (102A, 102B) and being radially compressed by a sleeve (104) made of a non-magnetic high strength metal. At least one (102A) of the first and second end shafts (102A, 102B) comprises, in its portion facing the cylindrical core (101), a central shoulder head (103A) which cooperates with a mating central recess (106A) made in a central portion of a front face of the cylindrical core (101).
    An easy concentric alignment of the first and second end shafts (102A, 102B) with the permanent magnet cylindrical core (101) is allowed while inserting the sleeve (104) and the stiffness of the assembled set is enhanced.

    摘要: An assembly comprises a rotating shaft (104, 114) supported with respect to a stationary housing (105, 115) by at least one active magnetic bearing presenting a mean radial air gap and at least one auxiliary bearing (118) comprising first and second coaxially arranged annular surfaces (124, 123), one (124) of the first and second coaxially arranged annular surfaces (124, 123) defining a clearance (E2) with one of the stationary housing (105, 115) and the rotating shaft (104, 114), the clearance (E2) being less than the mean radial air gap and the other (123) of the first and second coaxially arranged annular surfaces (124, 123) being integral with the other one of the stationary housing (105, 115) and the rotating shaft (104, 114). The auxiliary bearing (118) comprises a first ball bearing and a second ball bearing having a misalignment with respect to each other in order to increase the starting torque.
