摘要： A sealing arrangement for an electric machine, which is between a first part (104) attached to a rotatable shaft (106) and a second part (102) immobile with respect to a stator of the electric machine (10) comprises a plurality of zig-zag sections (110) of a channel of a labyrinth seal (108) in a radial direction of the electric machine (10). The channel of the labyrinth seal (108) includes a second seal (112) which is fixedly attached to the first part (104) and which has an elastic material part (114), the second seal (112) is pressed in the radial direction against a surface (118) of the second part (102), a normal of which has a component parallel to the radial direction, at rotational speeds a centrifugal force of which to the second seal (112) is weaker than a spring force of the second seal (112), and the second seal (112) opening a gap (120) between the second seal (112) and said surface (118) at rotational speeds the centrifugal force of which to the second seal (112) is greater than the spring force of the second seal (112).

摘要： The invention relates to a rotor for a synchronous reluctance electric machine. It comprises a stack of consecutive magnetically conductive core elements (101-104); each core element (101-104) comprises at least two adjacent sectorial sections (SI-S4') with flux barriers (FB11- FB14, FB21-FB24, FB31-FB34, FB41-FB44) and a central area (CA) surrounding the rotational axis (RA). A binding structure comprises core end plates (PL1, PL2) which form together with interconnection casts (C1-C4) a unitary casted structure. The interconnection casts (C1-C4) are casted into channels (CH1-CH4) extending through the stack and which are located in an area defined by the flux barriers (FB11, FB21) of the adjacent sectorial sections (S1-S2, S2-S3, S3-S4, S4-S1) and the central area (CA) of each core element.
