ABSTRACT:
Prior art stators of brushless DC motors are securely connected with the bearing support member, and/or with the fastening flange. The printed circuit board with electronic components for commutation is arranged for space reasons between the fastening flange and the stator. This type of construction makes difficult impossible an exchange of defective components. A removable stator is proposed which is retained and secured by means of only a spring element that compensates for tolerance variations in replacement parts.
