A stator for an electric motor, in particular for an external rotor motor, has a basic body () with a laminated stator core and with stator coils arranged on the laminated stator core. Each of the stator coils has a winding wire start and a winding wire end. Each winding wire start is attached to contact pins. The basic body () is extrusion-coated with a sleeve made from plastic, from which contact pins at least partially protrude. In order to reduce the manufacturing costs, a contact holder () encased in the sleeve together with the basic body () is pushed via the free ends of the contact pins onto the basic body (), wherein the contact holder () encases the contact pins with a sealing section () in a gap-free, sealing manner.

Stator for an electric motor

The present invention relates to a fan blade for axial fans with a blade body comprising an inner inlaid part and an outer blade shaped part partially enclosing said inner inlaid part. The outer blade is made of a material of lower rigidity than the inlaid part. The inlaid part is constructed as a substantially flat metal part adapted to the shape of the blade body and in the fan blade base region has an unencapsulated smooth fixing section.
