Abstract
A stator unit for an electric motor, in particular an external rotor motor, includes a stator with a stator laminate stack and stator windings and a stator bushing and a stator flange which is formed at one end. A housing flange of a housing for accommodating a motor controller or the like is fastened on the stator flange, and with motor connection contacts, which run from the stator through through-openings in the housing flange, and with fastening means, which run through fastening holes in the housing flange and are fastened in the stator. A sealing disk is arranged between the stator and the housing flange. The sealing disk has sealing regions made from elastic plastic, which are arranged and designed in such a way that direct and/or indirect sealing of the through-openings and/or the fastening holes is provided against the ingress of moisture.
