Zusammenfassung:The machine i.e. electric motor (1), has a stator (2), and a rotor (4) rotatably mounted in the stator. Bearing shields (7, 9) are provided with bearings (8, 10) at front ends of the stator. The bearing shields are separated from the stator, where a radial position of the bearing shields is adjusted with respect to the stator. The bearing shields are welded with the stator, and a power electronics (11) is held in the bearing shields. The stator is connected to a stator housing (3), and the bearing shields are connected with the stator housing. An independent claim is also included for a method for manufacturing an electric machine. Eine elektrische Maschine weist einen Stator und einen drehbar gelagerten Rotor auf, wobei zwei Lagerschilde mit jeweils einem Lager an den Stirnseiten des Stators vorgesehen sind, die separat vom Stator ausgebildet sind, und die radiale Position der Lagerschilde in Bezug auf den Stator einstellbar ist.
