摘要

A rotor (10) has at the centre a core (12) around which are several permanent magnets retained by a fine mesh (16). The magnets are fixed to the face of the core in one cold operation. One device allows the core, magnets and envelope to be correctly aligned. A second device spaces the permanent magnets at regular intervals and holds in place until cold compression is applied. End plates (14) are positioned on the axis until finally the magnets and core assembly is treated with adhesive.
