The shaft on which the rotor is secured is mounted via anti-friction bearings in a sleeve which, in turn, is spaced from the housing by spacer means of low heat conductivity. In addition, at least one heat-conducting means of high heat conductivity connects the sleeve to the housing in heat conductive relation. The heat generated during rotation of the rotor shaft is dissipated through the heat conducting means to allow increased rotational speeds, for example, up to 55,000 rpm. |
