Abstract
An electric drive motor includes a stator with pole shoes and at least one electrically controllable stator winding. A permanent magnet rotor is rotatably mounted in the field of the stator winding leaving an annular gap. The rotor includes a motor shaft and a laminated core on the shaft. The core includes at least a number of permanent magnets corresponding to the number of poles of the rotor. The magnets in the core are coated with a plastic envelope having at least one side wall covering the core on at least one axial front side. The side wall includes at least one recess freeing areas of the axial front side covered by the side wall, as access openings for boring the core to balance the rotor. A household appliance has the electric drive motor and an injection mold is used for producing the electric drive motor coated with the envelope.
