An electric machine comprising a stator (), a rotor () radially inward of the stator and comprising a plurality of surface permanent magnets () and a rotor sleeve () surrounding the rotor. The rotor sleeve comprises a plurality of layers of fibre reinforced matrix material (). The rotor sleeve defines a rotor sleeve radius to radial thickness ratio (r:t) between 20 and 40, and the electric machine has a maximum rotor rotational speed greater than 15000 RPM.

Electric machine rotor sleeve

An example stator tube assembly includes a hollow body defining a cavity and having a longitudinal length and a radial thickness. The hollow body is configured to be disposed within a stator housing and to separate the cavity from a stator cavity within the stator housing. The hollow body comprises a first radial thickness along a first portion of its longitudinal length and a second radial thickness along a second portion of its longitudinal length, the second radial thickness being greater than the first radial thickness.
