Abstract

In order to achieve a high level of coaxiality between the rotor and the stator bore the two hood-shaped housing parts (171, 172) of the housing (17) encompassing the stator laminated core (10) with the stator winding are centred directly in a radial manner, for which purpose the one housing part (171) supports on its end facing the other housing part (172) a coaxial centring connection piece (22) with an outer circumferential, turn-finished locating surface (23) and on the other housing part (172) structural elements (24) are arranged in rotational angular spaced disposition with respect to each other, which structural elements engage with an inner curved portion (241) over the locating surface (23). The stator laminated core (10) is fixed by way of a plurality of middle laminae (14) of the stator laminated core (10), which laminae protrude with projections (16) radially beyond the periphery of the stator laminated core and are received in a substantially form-locking manner between mutually opposite cheeks of the structural elements (24) (Fig. 1).
