Abstract

<div notation="docdba" type="abstract" xml:lang="en"><p>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).</p></div>
