A method of securing one or more insulated winding components in the slots of a rotary electrical machine against any displacement during operation in which one or more inserts which have a deformable and heat-hardenable characteristic such as is established by a fibrous material impregnated with a heat-hardenable resin in the B-state, are inserted in the slot in contact with the adjoining side of a winding component. The winding components and non-hardened inserts are then subjected to pressure to effect a deformation matching any tolerance irregularity in the profile of the adjacent surface of the winding component, this step being followed by a gradual heating of the inserts while still under pressure so as to harden the same, and the entrance to the slot is then closed in the usual manner by insertion of a wedge. |
