Abstract
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.
