Abstract: The laminated core (12) comprises laminations (10), which are arranged one over the other and which are each connected to each other by means of a first connection (9, 15). In addition, at least some of the laminations (10) are connected to each other by means of a second connection (11). By using two connections, the advantages thereof can be bundled, whereby the number and/or size of the connection points can be reduced while the requirement for the laminated core (12) remains the same or very high requirements for the laminated core (12) can be met or even increased. Advantageously, an adhesive is used as one of the connections (11), while the other connection (9, 15) can be a form-fitting connection. The adhesive (11) is applied to the lower side (13) and/or upper side (14) of the laminations (10) before or after the punching of the laminations (10). However, the two connections can also be formed by two adhesive systems. Finally, the connections (9, 10; 11) can also be formed by at least one weld seam and additionally by an adhesive.

Included are: a resin supplying unit (25) which feeds the resin; and a resin injection unit (15) which injects the resin into an axial hole (14) of the laminated core. The resin injection unit (15) has an injection pipe (16) and an elastic ring (19) attached to the injection pipe (16). This elastic ring (19) is made to firmly attach to the inner periphery of the axial hole (14); the resin is supplied from the resin supplying unit (25); and the resin is injected into the gap of the laminated core through the axial hole (14) of the laminated core.

Abstract: A rotor (2) of an electrical machine is arranged on a rotor shaft (3). The rotor shaft (3) is rotatably supported in bearings (4) so that the rotor (2) can be rotated about an axis of rotation (5). A stator (1) of the electrical machine extends over a stator region (6) in an axial direction. In the axial direction, the rotor (2) has a centre region (7a) and outer regions (7b) adjacent to the centre region (7a) on both sides. The centre region (7a) corresponds to the stator region (6) in the axial direction. The rotor (2) bears a number of tangentially magnetised permanent magnets (8), which are tangentially evenly distributed and arranged both in the centre region (7a) and in the outer regions (7b) in the axial direction. Flux-guiding elements (10) are arranged tangentially between the permanent magnets (8), by means of which flux-guiding elements magnetic fields (B) coming from the permanent magnets (8) are directed radially toward the stator (1) and into the centre region (7a) in the axial direction. The flux-guiding elements (10) consist of a plurality of sheets (11) stacked one on the other in the axial direction. The sheets (11) in the outer regions (7b) are smaller than the sheets (11) in the centre region. The sheets (11) arranged in the outer regions (7b) are surrounded radially on the outside by a retaining apparatus (12). By means of form-fitting elements (13 to 16), centrifugal forces acting on the sheets (11) arranged in the centre region (7a) are transmitted into the sheets (11) arranged in the outer regions (7b).
