In a rotor set for an electric motor or generator having a rotor core (4) and at least one insulating end plate (8, 9) comprising an inner region (13) and an edge region (14) equipped with cutouts (15), said insulating end plate being provided for the insulation of a face of the rotor core (4) in the opposite direction of the rotor winding, the insulating end plate (8, 9) according to the invention comprises a recess (16) in the inner region (13) on the side facing away from the rotor core (4), wherein the thickness of the insulating end plate (8, 9) is lower in the region of the recess (16) than the leakage gap stipulated by VDE EN 60335-1:1994 between the rotor core (4) and the rotor winding. The recess (16) can receive a coil head (7) and may counteract any uncontrolled collecting of resin in the contact region between the coil head (6) and the insulating end plate (8, 9). The present invention advantageously enables the more compact design of electrical motors and generators, thus saving material and costs. Furthermore, household appliances having electrical motors of smaller lengths, for example, may be configured in a more compact form, and/or their weight can be reduced. Additionally, quieter and more low-wear motors and generators can be produced by means of the invention. |
