A constant air gap between rotor and stator is crucial for the functioning and efficiency of the electric motor. In addition to the coaxiality of the bearing and stator bores, the roundness and cylindrical shape of the bearing seat are decisive for this. In order to meet the high coaxiality demands, it is advantageous to machine the bearing seat in one clamping setup (retraction machining). In the case of tubular or pot-shaped housing, there is at least one bearing point in a separate bearing cover, which is positioned on the electric motor housing via position bores or fitting surfaces.
