A method of applying a pre-tensioned, metal containment shroud to a rotor of a permanent magnet machine where pressure is applied to the inside of the shroud to stretch it so that the rotor may be inserted. This pressurization can also be used to size the shroud if the yield strength of the containment shroud is exceeded during the stretching process. The containment cylinder is proportioned such that on the removal of the pressure, the cylinder will have the required tension to clamp the permanent magnets to the rotor.
