<p>An electric motor has an impregnated stack of stator laminations 3 with contact surfaces 31, 32 at its axial ends, and bearing plates connected to the contact surfaces 31, 32 of the stack of stator laminations 3. In order to achieve a good electrical contact between the stack of stator laminations 3 and the bearing plates and, circumstances permitting, a simultaneously perpendicular and plane parallel positioning of the bearing plates without splinter-producing retreatment of the stack of stator laminations, the contact surfaces (31, 32) are provided with a plurality of depressions impressed into the stack of laminations (3). Depressions in the form of truncated pyramids are preferably impressed by means of a "rough planing process". The invention can be used to particular advantage in small motors with an insulated stack of stator laminations and a single protective conductor connection at the bearing plate. <IMAGE></p> |
