Abstract
The invention relates to a spindle driving motor, in particular an external rotor motor, the main components of which are accommodated in the interior of a driving hub (4) or the back iron (5). According to the invention, in order to minimize the number of joints, both ball bearings (11, 12) are arranged directly, yet correctly as far as assembly is concerned, between the fixed shaft (10) and the back iron (5), a collar (15) having a larger diameter serving in particular to this end.
