<p>A rotor assembly (10) comprising a shaft (11) and an impeller (12) and/or a rotor core(13). The shaft (11) is secured within a bore (15, 16) in the impeller (12) and/or rotor core (13) by adhesive (17) such that the tolerance in the concentricity of the shaft (11) is smaller than that of the bore(15, 16). A method of manufacturing the rotor assembly (10) is also described.</p> |
