Abstract

A motor having a stator and a rotor is provided as a direct drive for a laundry treatment appliance. The stator of the motor is preferably centered by a preferably cylindrical or conical protuberance in a bearing hole in a bearing spider or a rear wall of a tub of the laundry treatment appliance. The stator may have lugs on pole insulation which guide the rotor during installation, so that permanent-magnet poles of the rotor cannot strike soft-magnetic poles of the stator. A method for installation of the motor is also provided.
