Abrégé
A rotor (101) for a permanent magnet machine comprises a shaft portion (102), a core portion (103) surrounding the shaft portion, permanent magnets (104, 105) on an outer surface of the core portion, and pole elements (106) on top of the permanent magnets so that the permanent magnets are between the core portion and the pole elements The rotor comprises tension elements (107) having first edges shape locked to axially directed grooves of the core portion and second edges shape locked to axially directed grooves of the pole elements. Each tension element has tensile stress between its first and second edges, and thus the tension elements pull the pole elements against the permanent magnets. Each tension element can be for example an axially directed I-profile bar, and thus the tension element can be mechanically stronger than a row of bolts having a corresponding room usage in the circumferential direction.

The invention relates to a rotating group of an open circuit variable displacement hydrostatic axial piston unit of the swashplate design. The rotating group has a cylinder block rotatable around a rotating axis and a swashplate tiltable around a swashplate tilt axis. The swashplate tilt axis is perpendicular to the rotating axis. In the cylinder block a plurality of working pistons is arranged reciprocally moveable in cylinder bores oriented basically parallel to the rotating axis. A deflection force of a bias device acting on the swashplate generates a swivel-out moment on the swashplate swiveling the swashplate out of the neutral position. A restoring force created by the reciprocating working pistons on the swashplate generates a swivel-back moment on the swashplate counteracting the swivel-out moment due to an axial offset between the swashplate tilt axis and the rotating axis.
